1 Ball Bearing, 7 Pieces, 2 Billion Varieties

At first glance, the design of a ball bearing is clear: an inner ring is mounted with an outer ring, the appropriate balls and retainer. Then, the ball bearing is combined with the lubricant adapted to the requirements of use and, if necessary, a shield to protect against contamination.

Due to the numerous rules and recommendations for installation in the bearing area, the external dimensions of the different ball bearing manufacturers differ only in nuances. The large differences are evident in the internal values ​​of the ball bearing, the materials used for the rings and seals, the number of balls and their diameter, the surface structure and the precision of the profile, as well as the lubricant used.

350,000 RPM separable ball bearing GRW has, as required, three different materials to choose from for ball bearing rings. You can choose between 100Cr6, X65Cr13 (SS) or X35CrMoN15-1 (SV30).

Regardless of whether the customer's focus is on hardness, operating temperature or corrosion resistance, in the hardening process developed by GRW, the desired properties can be specifically invoked and implemented in the internal hardening workshop. In order to obtain additional functional properties of the bearing ring, coatings can also be provided.

For a long time, GRW has invested significant development effort in the coating of ball bearings. The objective of this development is, among other things, to improve tribological behavior or increase corrosion resistance. Whether as a dry lubricant to increase dry running properties or for high vacuum use, GRW offers the best solution for every requirement, with now more than 90 different coating varieties. The most recent development in this area is a hybrid band of metal and plastic (patent: EP000001832765B1). In this way, a metal band is coated with a thin and solid PTFE sheet and then formed into a steel tape retainer. Due to the low coefficients of PTFE friction, ball bearings with the lowest friction moments and excellent dry running life can be achieved with this retention liner.

In addition, the most recent procedures are used through PVD (physical vapor deposition) or CVD (chemical vapor deposition) and meet the highest standards of coating quality. An unwanted dissolution of the coating will result in a serious early bearing failure. Therefore, all coating varieties are subject to strict GRW standards and quality tests.

Torlon Snap Retainer The retainer must hold the balls at the same distance from each other and avoid touching each other. In addition, the retainer must have an appropriate design with defined material strengths and balanced elasticity, to withstand the ball bearing load as well as possible.

In addition to the strict tolerance specifications for GRW ball bearing rings with respect to surface finish, shape accuracy and steel purity, the same requirements apply to the design and production of the retainer. There are 3 basic variants for retainers: inner ring, outer ring or ball-controlled retainer. 

These basic types can be combined with 21 different materials. The material selection covers the entire range, from metal tapes for steel tape retainers to special aviation and spaceflight materials, to chemically coupled “PAI - PTFE-cg” plastic for heavy applications for applications with the most high standards of wear behavior, temperature resistance and sterilization capacity.

Lubricants serve to reduce friction and wear, as well as cooling, shock absorption, sealing effect and corrosion protection. Lubrication can be carried out using greases or oils and / or in special cases solid lubricants. All 3 types are recovered in GRW products. The installation situation of the ball bearing is crucial for the selection of a suitable lubricant. Grease lubrication is recommended for general use at low to medium speeds and, therefore, is the most commonly used type of lubrication. The main part of the lubricating grease consists of base oil and the smallest part consists of the appropriate thickener. The lubrication of the bearings is mainly done with base oil, which releases the thickener in small amounts over time. GRW uses lime soaps, natron soaps, lithium soaps and complex soapy fats.

Oil lubrication is used if grease lubrication cannot be used for technical or economic reasons. This may be the case with high operating temperatures, caused by ambient temperature or frictional heat in the ball bearing. The oils are divided into mineral and synthetic oils. Animal or vegetable oils are not suitable or only suitable to some extent for use in ball bearings. In total, more than 400 lubricants are used in GRW and, therefore, cover a large area of ​​use, from the food industry to aviation and spaceflight.

Various types of shileds in ball bearings Finally, the shield is mounted on the ball bearing as the last component. This should keep the impurities away from the high precision functional surfaces of the bearing and, therefore, produce as little friction as possible. On the other hand, this should keep the lubricant in the bearing. Impurities that get between the ball and the raceway will tip over and damage the processed tracks. To avoid this, contactless protectors and contact protectors are offered, with various sealing qualities.
carbon steel balls, chrome steel balls, stainless steel media, stainless media, zirconium beads

With contactless protectors there is no increase in torque, since the protector creates a separation ring. It does not produce friction and, therefore, can be used even at the highest speeds.

With the contact protector, the so-called ball bearing seal touches the shoulder of the inner ring with a defined contact pressure and, therefore, causes a greater moment of friction. Compared to contactless protectors, all contact protectors will wear out over time. Dust protectors are mainly produced from stainless steel or Perbunan rubber reinforced with steelsheets. The established seals are made of a fiberglass reinforced Teflon disc or a synthetic fluorine rubber reinforced with steel sheets. In total there are 63 shield variants to choose from.

At GRW, individual products are made of these components for the customer's special requirements. Due to a sensible combination strategy of standard and special components, GRW can satisfy the most diverse market requirements and guarantee our customers a competitive advantage.

The extensive and competent advice and design of a ball bearing are the prerequisites for the highest compliance with the established requirements. Even in the development phase of new applications, GRW engineers can provide valuable technical information and, for the most part, also cost savings.

Producing Ceramic Grinding Media through Drip Casting

Ceramic Grinding Media

A new method has been developed to synthesize ceramic microspheres as grinding media by dripping ceramic grout.

The need for minerals with a fine size (nanometers) has increased in recent years. With the resulting increase in ultrafine grinding, the science of comminution has achieved a range of micrometer sizes. For severe milling, high quality grinding media is needed, and several cutting-edge production technologies have been developed.

The dripping of metal oxides is derived from the process of storing nuclear fuel cells. Recently, this technique has been applied in the ceramic and pharmaceutical industries. One of the most important applications, the milling equipment, has experienced improvements in many of its mechanical properties. In fact, the most important quality of grinding media is wear resistance.

Due to their better resistance to fading compared to dyes, water-based pigmented inks are gaining interest in recent developments in inkjet technology. The size and shape of these particles, together with the degree of dispersion and the tendency to agglomerate, are important parameters for the manufacture of ink that can be met by using an appropriate grindingmedium.

Synthesizing Grinding Media

A recent study investigated a training method that uses sol-gel technology to synthesize ceramic microspheres as grinding media by dripping ceramic grout. A recently developed suspension process was used for actinide oxides and metal oxides (for example, Al2O3, TiO2, SiO2, ZrO2, HfO2, CeO2). The sphericity and smoothness of the surface of the particles produced by these processes are crucial, since these properties are traditionally desirable.\

Drip molding is a process that produces alumina pearls from an alumina sun by dripping a ceramic suspension through a nozzle plate to form drops and then harden the drops in a saline solution. This can be achieved by solidifying the ceramic suspension in situ by polymerizing sodium alginate monomers. Sodium alginate is the sodium salt of alginic acid, a polysaccharide composed of mannuronic and guluronic acids (acids are produced naturally by brown algae). The ceramic particles are maintained in a three-dimensional network. The mechanism of crosslinking in alginate gels can be considered in terms of an "egg box" model that involves the cooperative union of divalent metal ions between aligned polyguluronate tapes (Braccini I., 1999).

Gravitational force induces a ceramic suspension to drip into a saline solution (see Figure 1). At this point, the gelation polymer in the suspension becomes spheres, in which the sodium cation is replaced by a divalent cation and immediate and irreversible gelation occurs.

With this method of formation, it is possible to produce a variety of ceramic microspheres, such as grinding media and catalytic supports. By sintering the molten particles by dripping, it is possible to achieve good mechanical strength in the ceramic beads. To produce ceramic particles with maximum strength, the particles must contain a minimum porosity and the pores must be kept as small as possible. The particles must be spherical, with a smooth surface and a single mode size.

Drip Casting Versatility

The good results of the wear test and the crush test confirm the hypothesis that the achievement of dripping is a good method of synthesis. More developments are being made in the field of drip. Due to ceramic synthesis technology, finer particle sizes can be produced, in submicron order (for example, 0.01-0.10 µm).

In addition, the drip casting technique can be applied to many different substances, offering a new manufacturing technique for many applications. The simplicity of this technology allows an efficient manufacturing process and offers the possibility of modifying the initial configuration of a project to adapt to specific purposes. The knowledge behind the physics of gout formation helps lab technicians anticipate the shape and path of gout. Finally, drip molding gives technicians the opportunity to be creative and create as many different types of spheres as possible.

The versatility of this technology has allowed the study of many different products, each with the idea that there is no type of "universal" grinding medium. Each formulation has its own properties and method of application.

Identification of an ideal grinding medium

The ideal medium for ultra-fine grinding has several reproducible characteristics1:

• Chemical composition
• Hardness (related to chemical composition and grain size)
• high sphericity
• high roundness
• Competition (mechanical integrity)

Specific gravity, as designed for machine operation / mineral breakage requirements

Bulk density, hardness and fracture resistance are the key physical properties of a ceramic bead. The bulk density has a significant influence on the energy absorption of the mill. The wear resistance, hardness and fracture resistance of ceramic media also influence the mill parameters, such as energy efficiency, internal wear and operating costs. The advantages of the property, the reasonable cost and a low degradation of the mineral surface are the objectives of a good ultra-fine grinding process.

Analyzing Drip Casting Effectiveness

The objective of analyzing dripped alumina spheres is to demonstrate the effectiveness of drip casting when ceramic grinding media are produced. By modifying the characteristics of the microstructure, raw materials and ceramic production processes directly affect all ceramic properties, including mechanical properties such as compressive strength, fracture toughness, hardness and abrasion resistance 92% samples of alumina produced by drip casting were analyzed by measuring specific gravity and sphericity; Additional analyzes included a wear test, a scanning electron microscope (SEM) image, X-ray diffraction (XRD) and mechanical properties with a crush test.

The XRD analysis shows the composition of the drip spheres and it is possible to observe the absence of other chemical elements. In fact, although drip molding used an excess of sodium (derived from alginate) and calcium (derived from a saline solution), the diffractometer analysis lacks any trace of such elements.

The specific gravity of the drip alumina spheres increases to a value of 3.70 g / cc. This increase in bulk density could mean that the drip casting technique increases the density during sintering. High density is a desirable property in ceramic grinding media; In wear tests, spheres with a high density show more resistance than those with a low density. Another confirmation of this hypothesis has been obtained with the internal observation of sphere samples. Ceramic spheres seem full and densely packed. Despite a small closed porosity, the accounts do not exhibit macroscopic defects.

The internal aspect is easy to see after cutting the spheres. The dripped spheres seem to exhibit a good density, and the roundness of the media is regular, with a high degree of sphericity (close to the value of the unit). The average of the measurements of the entire perimeter is representative of the roundness of the surface of the pearls, which has been measured with an optical profilometer; therefore, the sphericity (or appearance) near one has been evaluated for all dripping pearls. Table 1 shows the geometric parameters of the spheres formed by drip casting.

The resistance of a ceramic sphere can be determined from the crush resistance test of the proppant described in ISO 13503-2: Measurement of the properties of the proppants used in the operations of hydraulic fracturing and gravel packing. In this test, a proppant sample is first screened to remove fines (granules or smaller fragments that may be present), then placed in a crushing cell where a piston is used to apply a confined closure effort of a certain magnitude (Newton) above The point of failure of some fraction of the proppant granules. The sample is screened again, and the weight percentage of the fines generated as a result of the pellet failure is reported as crushing percentage. A comparison of the crushing percentage of two samples of equal size is a method of measuring relative strength.

7 TIPS FOR CHOOSING ABRASIVE BLASTING MEDIA

Abrasive blasting, which is the process of using specialized machinery to project or "shoot" media at high speed through a hard surface, can be ideal for removing old finishes. You can also remove rust or prepare the surface to paint.

Here are 7 tips that can help you choose the best abrasive media for your specific shot blasting applications.

How to choose abrasive abrasive media

Better "soft" than sorry

Steel Tumbling Media, catalyst balls, forged steel grinding balls, forged steel balls, ceramic grinding media suppliers, Steel Tumbling Media, zirconium silicate beads, catalyst bed support balls, grinding balls, milling media, shot peening media, grinding media, stainless steel tumbling media

If you are not sure if the surface you are cleaning can handle a more abrasive material, it is probably best to start with a softer medium. Nutshells or corncobs can be an excellent choice for softer surfaces such as wood, as they do not cause engraving. They also provide the additional benefit of being biodegradable, which makes them one of the most ecological blasting means.

Make it shine with glass beads

If you are looking for a smooth and shiny finish, glass beads may be your best option. Glass beads are generally made of thin glass of soda lime that exerts minimal stress on the surface material. Glass beads are also recyclable and can be used up to 100 times before replacement, which makes them an extremely cost effective option.

Remove paint with aluminum oxide

Aluminum oxide is harder and sharper than glass beads. It is ideal for use in paint removal and general cleaning applications. It is also frequently used for glass engraving.

Choose plastic for automotive and aerospace applications

The plastic is extremely soft, which makes it an ideal way to remove paint from the surface of fiberglass parts. Fiberglass parts are commonly used in the manufacture of automotive, aerospace and marine products, without engraving or peeling. The use of plastic for blasting also produces very low levels of dust.

Use silicon carbide for quick etching

Silicon carbide provides an extremely aggressive cutting action that is ideal for rapid etching of glass, stone or other hard surfaces. It also works well to remove rust or paint.

Find super tough and aggressive steel media

Media made of carbon steel are available in the form of shot. The steel shot is round in shape and can be used for polishing and polishing applications. Steel sand offers a more angular shape and a sharper texture. It can be used to remove rust, paint or flakes from steel surfaces.

Avoid sand

The terms "sandblasting" and "abrasive blasting" are sometimes used interchangeably. However, many companies are moving away from the sand as a means of blasting for several reasons. The sand contains silica, which is known to cause serious respiratory diseases for workers involved in the sandblasting process. In addition, the sand contains a high moisture content that can cause premature disappearance of blasting equipment.

FoxIndustries now offers abrasive blasting among its metal finishing processes. We are also available to provide reliable media selection advice.

Why Size Matters When Choosing Tumbling Media

Size is everything when choosing the right turning medium for a cleaning job. Ultimately, it will have an impact on the overall quality of the cleaning process. But the size of the parts is also important. In general, the media must be able to clean all surfaces of the parts without housing. So, the trick to achieve the best results is to carefully mix the pieces with the correct size media.

However, making that decision may seem like an easy task. In other words, problems may arise when the size of the media and the parties do not match.

Media Size

It is easy to choose the wrong media size when cleaning certain parts. If that happens, the parts could be damaged or the cleaning work will not be successful.

In general, larger media are good for quick deburring or finishing. On the other hand, smaller media will take longer to complete thecleaning work.

Different sizes of flip media

In addition to that, the results of the cleaning or polishing work will differ according to the size of the media. Larger media can damage fragile parts, while smaller media cannot. Similarly, larger media will leave rough marks, while smaller media will have a softer impact.

Sometimes, it is okay to mix media of different sizes to get the best results if only one size is ineffective. That is especially true when using steel means to clean metal parts.

Accommodation

Problems with accommodation are common when it comes to turning means. Typically, these problems occur when media gets stuck in parts that have holes or grooves. In other words, housing problems will surely happen when smaller means are used to clean large parts.

As a general rule, the media must be larger than any hole or space in one part. To prevent two pieces from being trapped in an opening, it is better to use media that are at least 70% larger. For example, the angled cutting cylinder means will easily pass through the holes.

The trick is to carefully choose the means that will do the job but will not be hosted in parts.

Use and throw

Constant friction corrodes the turning means. In other words, the media reduce their size due to use for a prolonged period of time. But the speed at which that will happen will depend on the media material. For example, organic media will be reduced in size faster than ceramic media due to wear.

However, means that are gradually reduced can also cause housing problems. Therefore, it is important to keep that aspect in mind as well, as it is easy to ignore.

Parts screening

If the media and parts are similar in size, it can be difficult to separate them after cleaning. In general, the means should be smaller than the parts, but not too small to avoid accommodation. The easiest way to separate parts of the media is to use a screen or a media separator. In some cases, magnets will also do the trick.

A Guide to Vibratory Finishing Media

What is Vibratory Finishing?

The vibratory finish is the final step in the plating process, and includes the grinding of unwanted burrs, smoothing sharp edges and providing a polished finish. The shape, material and size of the vibrating means vary according to the material, shape and strength of the pieces. The choice of the right finishing medium optimizes the quality of your finished product while providing profitable and mass produced results.

Types of Finishing Media

Finishing media materials include:

• Ceramic
• Plastic
• Steel
• Organic compounds

Other means, such as glass beads, are occasionally used; however, in most cases, their parts will end up using one or more of the four main media types.

Ceramics and Plastic Media

Ceramic and plastic media represent eighty to ninety percent of the finishing media. Ceramic media have a relatively high density and are used to grind and polish hard metals such as steel, stainless steel and titanium. Ceramic media also includes porcelain made of pure aluminum oxide. Porcelain is used for finer grinding and produces a high gloss finish.

Ceramic media is strong and durable, but can splinter. The loose chips in the finishing means can be housed in perforations and other small areas in metal parts.

Plastic media usually have a polyester base, but some media may be based on urea or formaldehyde. Plastic media are generally used for "softer" metals, such as aluminum, brass and zinc.

Both ceramic and plastic media are mixed with abrasives during finishing. Common abrasive types include silica, silicon carbide, aluminum oxide and zirconium. Silica, or sand, is used to debur and thaw softer metals. Silicon carbide and aluminum oxide are used for aggressive grinding, usually in harder metals. Zirconium is added to lighter plastic media to add some weight, and is used to finely grind all types of metals.

Steel and Organic Media

The steel means are made of hardened carbon and stainless steel, and are generally used to apply pressure to the pieces of deburred steel, as well as for the polishing of balls and the polishing of stainless steel (and occasionally aluminum).

At the other end of the steel's resistance spectrum is the organic finishing medium, which includes corncob granules and nutshells. Organic media is mainly used to dry parts after vibratory finishing. It can also be used to produce a high gloss finish in stainless steel, aluminum and other metals when mixed with a polishing paste.

The Importance of Shape

Finishing media come in a variety of sizes, from cylinders and balls to pyramids and sharp-edged stars. The shape of the pieces that are finished generally determines the shape of the finishing medium. For general use, round, oval and cylindrical media are preferred. Rounded surfaces wear well and are less likely to lodge in parts than materials with sharp edges. Round and cylindrical ceramic media also have lower chipping rates.

Triangles, arrowheads and three star shapes are more suitable for finishing complex parts with hard-to-reach sections, but have a higher wear rate and are more susceptible to splintering.

Size also matters when vibrating turning means are selected. Smaller media have more contact with the surface area of ​​the pieces than larger materials and produce a smoother and more attractive surface. Production times are longer for polishing small media, because the smaller finishing material requires smoother processing.

Larger media produce a rougher surface, but lend themselves to more aggressive grinding. The large finishing material provides quick burr removal and is also effective for rounding sharp edges.

Effects of Ball Burnishing Process with Stainless Steel Media

Expectations about manufacturing industries have increased in recent years. Different mechanical processes such as turning, milling, etc. they lead to surfaces with inherent irregularities. Therefore, manufacturing industries face the responsibility of finding improved finishing operations that nullify these effects and improve other properties in these materials.

Surface plastic deformation processes were created to solve these impediments. This process does not involve the removal of material, but rather deforms the surface plastically under compression load. Therefore, it is said that the surface of the component under this external load is subjected to cold work.

Burnishing is one of those techniques of surface plastic deformation. It has been around for a long time and has continued to gain general acceptance in today's manufacturing industry.

1. What is burnishing?

Burnishing is a process of surface modification through which smooth surface finishes are achieved. This is possible by planetary rotation of a tool on a turned surface board. In general, burnishing is a cold work process that softens, removes discoloration and polishes a metal surface in a glossy finish that is almost as good as new.

This specifically points to the peaks and valleys contained in all machines or other processed metal surfaces. The burnishing tool is applied with a calculated amount of force. This force drives the materials that until now were at the top to flow into the valleys. This effect will be a reduction in the height of the peak, as well as in the depth of the valley.

This method was first developed in the United States in the 1930s. The burnish was applied in an attempt to impart residual integral tension to layers of various metal parts, specifically the railroad, the automobile axle and the machinery axes. Over the years, it became widely accepted and has found applications in almost every industry in the world.

2. Types of burnishing

This process can be classified into different types according to the type of tool used, the geometry of the pieces in which it works, etc.

Taking into account the geometry of the tools used, the burnishing is further classified into two groups: ball burnishing and roller polishing. However, for the purpose of this article, we will consider ball burnishing, its definition, advantages and application in various industries and businesses in the world today.

Ball polishing: in this type of polishing, one or more spherical balls are supported on the rod by the hydraulic pressure of a fluid, a spring or the relative force of the workpiece. The ball is constantly in contact with the workpiece by means of fluid that circulates through a hydraulic pump. As the tool feeds along the workpiece, the ball is pressed against it, resulting in a burnishing operation.

Depending on the desired effect, the strength of the burnish can be controlled by varying the hydraulic pressure of the fluid.

3. Advantages of ball burnishing

• This process allows to produce pieces with a high control over the dimension and allowing very precise sizes.
• Produces a very smooth surface finish
• It saves costs and is more economical compared to other polishing processes
• Creates improvements in physical properties and increases the life of the components.

4. Benefits of ball burnishing with stainless steel media

Stainless steel media is particularly popular in surface finishing due to its superior characteristics. This has led him to become the most preferred and widely accepted in industries around the world.

Below are some inherent characteristics that make stainless steel media the most commonly used today:

• Greater surface pressure and longer media life
• Shortest Finnish Time
• Improves the pre-plate finish
• Reduces porosity in plated parts
• Economic

4.1 Higher surface pressure and longer media life

If used under appropriate conditions, this medium can last a long time. Obviously, this is because it is not a worn out means of communication. It has a high hardness due to its composition of relatively resistant materials. This feature is excellent for various vibratory flipping applications.

In addition, there is a minimum generation of solid waste during this process. Steel that is a non-consumable medium is not used throughout the operation.

4.2 Shortest Finnish time

Stainless steel turning means are comparatively heavier than other materials used for this process. This substantial weight exerts greater pressure on a mass of components in the vibratory, barrel and flipping finishing equipment. The high surface contact achieved through increased pressure and resistance of the steel means works effectively to shorten the operating time.

4.3 Improves the pre-place finish

The parts that seem smooth are characterized by micro imperfections that cause coating problems. Due to the weight of the steel means, these small irregularities flatten, preparing a surface for a more satisfactory coating.

4.4 Reduces porosity in plated parts

When the plated parts are finished with steel turning means, a compacting action acts downward and extends across the entire surface of the softer plate to fill any "pinhead" hole. This eliminates porosity and causes an increase in corrosion resistance created by the coating process.

4.5 Profitable

The durability of stainless steel media is considered a capital advantage. The finish made with this medium generally lasts longer. The use of stainless steel shots versus plain steel means eliminates the need for rust inhibitors.

5. Success stories in the application of stainless steel burnishing

The burnishing of brass components has become an economical solution to repair the nicks, scrapes and scratches developed by manufacturing. Companies and companies continue to look for better ways to maximize profits and reduce costs. Therefore, they have resorted to polishing as a means through which they can, among other advantages, avoid wear, improve gloss and extend the life of parts and components of the machine.

a) Brass mounting parts

Glass Bead Media

Foxindustries Viscous Materials

The viscosity of its material will influence the effectiveness of its Foxindustries. Generally, the higher the viscosity, the lower the Foxindustries efficiency. Viscosity ratings for your Foxindustries are often given in centipoise (cP) or millipascal-second (mPas; 1 cP = 1 mPas). The ratings may vary from 1000 cP for simple hand-rotor-stator Foxindustries to 10,000 cP for high-power table models. To quickly estimate the viscosity of your sample, you can compare it with the known viscosity of the common materials shown in the following scheme and see how it compares with the viscosity classification of your Foxindustries.

The effect of viscous materials on Foxindustries depends on the type of Foxindustries used, but it is generally true that the higher the output power, the better the mixture of more viscous materials. For probe-based Foxindustries (ultrasonic or rotor stator), the volume that can be processed efficiently decreases significantly (up to an order of magnitude) with increasing viscosity. Mixing cycles should also be kept as short as possible (3 minutes maximum) to avoid overheating the engine.

Generally, the effectiveness of rotor-stator Foxindustries decays rapidly with increasing viscosity. 10000 cP is usually the maximum processable viscosity with rotor-stator Foxindustries. To improve the mixture of viscous samples, separate probe heads can be used. For example, PRO scientific baffle heads are specially designed to improve the Foxindustries of higher viscosity materials. It is advisable to move the rotor-stator as much as possible so that all areas of viscous materials are mixed.

Ultrasonic Foxindustries are somewhat less affected by the viscosity of their material. They are based on pressure waves that create bubbles. The collapse of these bubbles creates energy that disrupts the material and allows mixing. Materials with higher viscosity move less easily than more watery ones and, therefore, exert pressure on the bubbles, which makes the mixture more efficient. This, however, only works up to a certain viscosity. If your material becomes too viscous, it cannot be processed effectively. A good rule of thumb is that "if you can't pour it, you can't sonicate it."

Ball mill Foxindustries are much less suitable for viscous materials, since they use beads to Foxindustries the material. If the accounts cannot pass freely through the material, they cannot Foxindustries it.

High pressure Foxindustries use high pressure to force your sample through small slits. In order for them to work properly, your sample must be fluid enough to be effectively pumped.

There are some vision tricks to overcome some of the difficulties in Foxindustries viscous samples and processing highly viscous materials without significantly diminishing the effectiveness of their Foxindustries. The viscosity of a material decreases with increasing temperature. Therefore, performing Foxindustries at higher temperatures will generally provide better mixing results. It is important to check the decomposition temperature of your material before Foxindustries it at higher temperatures so that it does not destroy your sample. Another way to decrease the viscosity of your material is by adding surfactant and emulsifiers. These can break the internal resistance and allow the material to move more freely and, therefore, become less viscous.

No matter what type of Foxindustries you use, mixing viscous materials will always be more difficult than mixing aqueous mixtures. You can realize this by processing smaller batches of material and, for handheld devices, by moving the mixing head more rigorously to improve Foxindustries. 

Alternatively, you can increase the processing temperature or add surfactants and emulsifiers to your sample to decrease its viscosity.
