The mesh plays a critical role in achieving uniformity in the particle size of the grounded material.

6.Which Industries Are The Powder Grinder Mainly Used?

The powder grinder is used in a variety of industries. Below are some of the industries that use powder grinders.

The Pharmaceutical Industry

Medicated Capsules

The powder grinder is most extensively used in the pharmaceutical industry. This is because the particle size plays a very important role in determining the pharmacokinetics and pharmacodynamics of the drugs.

The main goals achieved by particle size reduction include increasing surface area and maintaining uniform particle size.

Increased surface area makes dissolution of the particles faster and easier. Uniformity in the particle sizes ensures homogenous mixing of the particles.

The powder grinder is used in the pharmaceutical industry for grinding the powders and granules for solid and liquid dosage forms such as tablets, capsules, emulsions and suspensions etc.

The Food Industry

Powdered Spices

The powder grinder is used in food industry for grinding a variety of materials such as spices, pulses, sugar and many other ingredients for making different food products.

The main goal here is also the same as in the pharmaceutical industry. That is, grinding the material to increase the surface area and maintain uniformity of particle size.

Smaller particle size helps the food industry by making the storage of ingredients easier. Smaller particle size also increases the mixing characteristics of many ingredients.

The Cosmetics Industry

Face Powder in Cosmetics Industry

The powder grinder is very widely used in the cosmetic industry for making different cosmetic products such as face powders, creams, nail paints etc.

The fineness and uniformity of the particle size in the cosmetics products are very important factors in determining the texture of the product.

Of course a smooth texture can be obtained by grinding the particles to fine sizes. This task is done by the powder grinder.

The Paint Industry

The paint industry also uses the powder grinder very frequently for reducing the particle size and maintenance of uniformity in the particle size.

7.What Types Of Products Can You Grind With Powder Grinder?

As already discussed that a powder grinder is a very versatile device and is used to grind many different kinds of products. Some of these products are described below.

Solids

The powder grinder is used to grind solids into fine and ultra-fine powders. Both brittle and tough solids can be ground by using the powder grinder.

Powders

Powdered Drug

The powder grinder is used extensively to convert powders into finer particles. This practice is very frequently used in the pharmaceutical, food and cosmetics industries for making a variety of products.

Granules

The powder grinder is used for grinding the granules too. Both wet and dry granules can be easily grounded by the application of the powder grinder.

8.How Is Grinding Different From Machining?

Machining refers to the cutting of the material into desired size and designated shape through a process of material removal. While grinding means reducing the particle size of the material.

Another important difference between machining and grinding is that the process of grinding offers more dimensional accuracy than the process of machining.

9.What Points Should You Pay Attention To When Choosing a Powder Grinder?

When choosing a power grinder for your industry of work you need to be careful. There are different perspectives you should look before choosing a powder grinder. Some of the points are mentioned below.

Compatibility

While choosing a powder grinder you must have your organizational needs in mind. The selection of the grinder can not be made without thinking about your works and your needs. There are many ways to check the compatibility of the grinder like size, speed, space required, budget, capacity of grinding and power consumption

Speed of the grinder

Speed plays an important role in making a power grinder important. If you are choosing a grinder for your kitchen tasks so speed will not matter that much, but if you have to choose for an industry then you must pay attention on the speed because the industry demands more work in less time.

Generally, the speed of rpm is measured in rpm that is rotation per minute. The large industries require machine with high rpm so the machine with at least 32000 rpm. But in home we can sometime compromise on speed.

Space Required

For instance, if you must select a powder grinder for your daily small tasks such as grinding rice so do not need a big machine-like grain mill it will consume more space in your kitchen. You can go with an electrical angle grinder which is small and handy.

Capacity

Capacity refers to how much a grinder can grind. The grinders like electrical angle grinders are just for little quantity. On an average they can grind 40 kg of the material per hour but of you have to deal with large quantity like grinding flour you must shift to large grinders.

10.Which Type Of Powder Grinder Is Best For Home Use?

There are many types of powder grinders that are in use nowadays and each one of them has their own specified field in which the work the best.

The choice of grinder depends upon a number of factors such as the type of material to be grounded or the amount that needs to be grounded.

When we talk about the best possible powder grinder for domestic use, the most appropriate answer will be the cutter mill. This mil uses the shear force for size reduction.

The cutter mill has two sets of blades. One set of blades is directly attached to the rotor and the other part is attached to the wall of the body or casing of the cutter mill.

The set of blades attached to the rotor are movable, therefore they are known as moveable or rotor blades. The other set of blades is stationary and cannot move or rotate. So they are known as stationary blades.

The rotor blades rotates when the machine is turned on, thus cutting the materials into smaller particles until they are small enough to be fine particles. The coupling action of the stationary blades is also very helpful during the whole process.

11.How To Solve Common Grinding Problems With Powder Grinding Machine?

Some of the most commonly existing problems along with their solution are discussed below.

Chatter

Chatter may be caused by a number of factors. Chatter is often identified by a distinct pattern on the workpiece that is often audible.

Slipping of the wheel on its mount is the most common cause of chatter. Resonance in the machine can also cause chatter due to vibration.

Solution

You need to check the wheel and make sure that the wheel does not slip on its mount anymore. Make sure that the wheel id carefully trued.

If the chatter still continues, try varying the speed of rotation of the powder grinder to avoid resonance. This may help reducing chatter.

Burning

The term burning refers to the thermal damage to thed powder grinder. Burning can occur if the wheel is facing a very high friction or it is getting rubbed strongly during its rotation.

The reason of friction or rubbing can be loading or glazing of the wheel.

Solution

Dressing the wheel correctly using the right dressing tool may help with reducing the friction, ultimately reducing the risks of the burning or thermal damage to your powder grinder.

Too short working life of wheel

The main reason behind short wheel life lies in the fact that you might be using a sub-standard wheel of low quality or you might be using a wheel that is not made for your powder grinder.

Solution

You just need to find the wheel that is best suited for your powder grinder. Also make sure that you use wheel of the best available quality.

Slow cutting by wheel

Another problem that is very frequently faced during the process of powder grinding is slow cutting operation by the wheel. Slow working or cutting by the wheel ca badly affect your productivity, badly affecting your finances.

Solution

You should try finding a wheel with a very high efficiency. The wheel that has the ability to grind fastest should be preferred.

Poor finish of surface

The poor finish is the major turn-off for the customers because it gives a very bad appearance. The fine and neat appearance of the powder is the first thing that customers notice while buying them.
