If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

A fluid energy mill is also known as a pulverizer, micronized, or jet mill. It is used for fine grinding and close particle size control. The reduction of the particles takes place by the attrition and impact mechanism by the air or inert gas introduced through the nozzles present in the chamber. This mill is mainly used to grind heatsensitive ...

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. Ball Mills vs ...

The length of the mill is approximately equal to its diameter. Principle of Ball Mill : Ball Mill Diagram. • The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed.
