How are the number of balls in ball mill grinding for. - ResearchGate

Commonly 1:10 (material:wt. of ball) ratio is used. More rpm means lesser milling time but you have to check rpm limitation of your milling machine. More rpm also induce contamination of iron, so carefully optimize the parameters with respect to desired final size of particles and tolerable level of contamination. Jagadesh P.

Ball Mills

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral.
