Application of Ball Mill
Ball mill is the key equipment for grinding materials into fine powder. It is widely applied in industry fields, such as cement making plant, silicate product, new type construction material, fireproofing, chemical fertilizer making plant, ore dressing plant, glass and ceramics making plant etc. It can grind various materials in dry or wet grinding method.

Structure of Ball Mill
This machine mainly consists of feeding device, discharge device, rotating device, transmission devices (gear box, pinion gear, motor and electric control device). The hollow shaft is made of cast steel. The liner is replaceable. The gear wheel adopts casting gear hobbing. The wear-resisting liner is inlayed in the cylinder of ball mill.

Ball mill can be divided into lattice and overflow ball mill in terms of discharging way. At present, they are the most common grinding machine in mineral processing plant.

Working Principle of Ball Mill (Overflow Type)

Overflow-type ball mill is a two-warehouse horizontal cylindrical rotation device with outer gear rotating. Material from the feed device is evenly fed into the first warehouse via the compound empty shaft spiral. In this warehouse there are ladder-shaped liners or corrugated liners, with different specifications steel balls inside. The rotating cylinder produces centrifugal force and brings the balls to a certain height, then, balls fall down and thump and grind the material. The material in the first warehouse will go to the second warehouse by monolayer partition panel after coarse grinding. The second warehouse is equipped with flat lining with steel balls inside, the material will be further grinded here. Powder product will be discharged through the discharge grate plate to complete the complete grinding operation.
