Professional Large Ball Mill - Great Wall

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, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.

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.

Ball mill is mainly composed of charging and discharging, cyclone and rotation parts (like redactor, minor rotationgear, motor, electric machine, etc). Hollow axis is made of steel partswith a lining replacable. Major rotation gear, machined by rollingwheel of casting, is lined with wearing plate with fine wear-resistingproperty. This machine runs stably and reliably. Based on difference of materials and discharging types, dry Ball mill and wet Ball mill are selectable.
