Ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a 

reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being 

recirculated back into the mill to be reduced. Various classifiers, such as screens, cyclones and air classifiers are used for 

classifying the discharge from ball mills. 

 

1. Application: 

Ball Mill is widely used in powder making production line in industries, like mining,building materials and chemistry industries.  It is a key equipment to grind all kinds of ores and other materials, including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

 

2. Working Principle:

The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
