Ball Mill

Ball mill is a crucial equipment for the material to be milled after crushing. widely used in cement, silicate products, new construction material, fireresisting material, fertilizer, ferrous and nonferrous metel processing, and glass ceramics ,etc, It is mainly used to mill all kinds of materials with or without water

Ball Mill  Working Theory

Dived by external gear,this ball mill is horizontally tubular running type device with two cavities. The raw material enters spirally and evenly into the first cavity through input middle hollow axle. In this part, there are ladder or ripple plates, as well as different types of steel ball. Formed during cylinder rotating,the centrifugal force brings those balls into a certain height. And consequently the materail is stricked and grinded. After that, the material enters through single layer plate into the second cavity for the further grinding, which had been embedded with flat plate and steel balls. In the end, the powder is discharged by output grate plate and the milling function have been realized.

Ball Mill Structure Characteristic
This machine is made up of feeding part, discharging part, gyre part, transmission part, (decelerator, small transmission gear, generator, electrical control ) and so on.  With casting steel fot the middle hollow axle, replacable lining, casting rolling gear for the rotating big gear embedded werable plates in the cylinder, the ball mill shows the characteristic of bearing well with wearing, running steadily and woking reliably.
