Ball Mill Principle, Construction, Working, and More Soln Pharma

Ball Mill Principle, Construction, Working, and More Soln Pharma

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
