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

Ball mills have been designed in standard sizes of the final products between mm and mm in diameter. 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.
