Get PriceEmail contactThe Compeb mill is a type of ball mill designed to incorporate the Preliminator and Ballpeb mills in one relatively long shell. The initial or primary grinding compartment is lined with thick liners and carries large balls to accomplish the coarse grind. This primary compartment is followed by one or more secondary compartments which are provided with thinner lining and smaller grinding bodies ...

Get PriceEmail contactThe attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm. Power input to attrition mills is used to agitate the medium, not to rotate or vibrate heavy drums. Therefore, specific ...

Get PriceEmail contactEnergy consumption for ball mills is a function of many factors: the physical properties of the ground material — its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency — no more than 15%. Energy is mainly consumed on the wear of grinding balls and mill housing, friction; heating the material etc ...

Get PriceEmail contactA ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...
