Ball mills are one of the oldest milling methods in the world. It’s a simple machine that uses the impact of balls in a chamber to mill different products. Even today it remains a very popular grinding method. Ball mills India uses the simplest machines with technological support to make the entire process quick and efficient.
Working Of The Ball Mills
The construction of the ball mill is pretty simple. It has a cylindrical device which rotates on a horizontal axis. This is the chamber which also contains the milling balls. Sometimes the milling chamber may be housed in a bigger protective vessel. The material to be grounded is fed into this chamber and as it rotates on its axis, the cascading balls pummel the material inside. It is an extremely easy method, which is also extremely effective in getting the results you want.
Why are ball mills still so popular? The answer lies in their effectiveness. The simple design banks on the working of the balls inside the mill
Cost of installation: Compared to other mills like pin mills or rod mills, the ball mill is a simple design which requires very little in terms of installation. There are high-end ball mills, including very large ball mills that are extremely efficient. However, there are plenty of options available in a more reasonable budget. The installation costs are generally quite low because of its ease of installation.
Cost of power: The ball mill does not require a lot of power. Mid-sized or small ball mills only need a little power for their operation. In fact, it is considered one of the most cost-effective milling methods.
Green tech: In many industries ball mills are seen as the best in green tech. It is a mechanical way of breaking down materials that does not depend on chemicals or other additives. In the food industry or in cellulose production, the mechanical ball mills are the safest and most non-polluting means of producing fine particles. The operation of the ball mills India requires very little energy, which adds to its benefit as a green tech.
For all degree of hardness: The ball mill can be used for any degree of hardness — from very hard substances to far lighter materials. It is used to grind hard materials like feldspar or plastic. It is equally useful in breaking down cellulose, however, we do have to consider a couple of factors here — density and hardness. The ball medium must be denser and harder than the material to be grounded. A lighter medium will settle on top of the material, which would defeat the whole purpose. Similarly, a medium will have no impact force if it is softer than the material.
Cheap grinding medium: Common grinding mediums are stainless steel, chrome steel, ceramic or rubber. None of these are expensive. In fact, all one has to consider is integrity, density, hardness, size and a non-corrosive composition. There is no special workmanship or installation requirements such as in the case of other mills.
Wet and dry grinding: Unlike most other mills, the ball mill is equally useful in wet and dry grinding. Most mills only work in dry grinding. With ball mills India we can effectively work with wet material as well. All we need is a little flow ability which liquid already has. We need just a little liquid to ensure that material keeps moving in the mill. In dry materials we use air flow to ensure that it keeps moving.
Wide range: The ball mill can work with a really wide range of materials that range from cellulose, ceramic, chemicals, fibers, pigments, metal oxides, polymers and more. It can work with almost any kind of material as long as we choose the right medium. The flexibility of picking the ball medium gives us a really wide range in application and work ability.
Applicable for batch and continuous operation: The ball mill can be used for batch operations where we grind some material at a time. But it is equally applicable in continuous operation where we need constant supply. This can be critical in manufacturing assembly lines.
Cost-effective: The ball mill is one of the most cost-effective milling solutions. This simple design is not expensive to build or install. There is no need for specialist installation within the mill or complicated calculations to decide how it should operate. Its energy consumption is also pretty low. This makes ball mills India one of the most economic mills to run.
