get price## What Is a Ball Mill?

For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material.

All cutting tools have a recommended cutting speed for any given material. Softer metals like aluminum and mild steel have higher cutting speeds than do nasty metals like titanium or Inconel. So, too, can carbide and ceramic cutting tools achieve higher speeds — regardless of the workpiece material — than do ones made of high-speed []

get price## Ball Mill

DEFINITON: • A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering etc. 6. PRINCIPLE: A ball mill works on the principle of impact and attrition. size reduction is done by impact as the balls drop from near the top of the shell.

get price## Cement mill

Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.
