• Ball MillEastman Rock Crusher

    Ball mill is a type of grinder machine which uses steel ball as grinding medium can crush and grind the materials to 35 mesh or finer adopted in open or close circuit. The feed materials can be dry or wet they are broken by the force of impact and attrition that created by the different sized balls.

    Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height or depth of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
