Ball Mill

According to the material and the way of discharging, users can choose a dry or a wet grid ball mill according to their materials and discharging methods. The wet ball mill is often equipped with a classifier whereas the dry one with a suction and separating device. Compared with the Raymond mill, the ball mill can grind metal ore.

Structure
The ball mill is mainly composed of a feeder, a discharging port, a turning device, transmitting devices that include a reduction gear, a small transmitting gear, a motor, and the electric control. The hollow shaft is made of cast steel so that the inner lining can be replaced. The rotary large gear is processed with the casting hob, and the barrel is equipped with wear-resistant lining, improving its wear resistance.

Working Principle

The material is uniformly fed into the first bin by the feeder through the hollow shaft. With a step or corrugated lining, the bin is filled with steel balls of different specifications. The cylinder generates centrifugal force by rotating and brings steel balls to a certain height and then throws them down , causing heavy impacting and grinding force on the material. After coarse grinding, the material enters the second warehouse through a single-layer compartment board. The warehouse is equipped with a flat lining plate also with steel balls to further grind the material. The powder is finally discharged from the mill through the baffle to complete the operation.
