Coal ball mill Overview

Coal ball mill is the equipment used for grinding and drying coal with different hardness. It is mainly composed of feeding device, principal axis, rotating part, transmission part, discharging part, high-pressure starting device and lubrication system. The coal grinder is also widely used to break various hardness of coal in cement industry, metallurgy industry and chemical industry and so on.

Ball Mill Working Principle

Center drive and side drive are two common drive modes for a ball mill. Center drive grinding mill means the motor shaft extends along the axis of mill body while side drive has a motor located on the side of the mill and torque is transmitted via the girth gear which is bolted on the flange of the mill body.

Materials are fed into the mill at a fixed flow rate along the shaft-less screw of the screw conveyor. Once inside the first compartment of the drum, the motor is activated and rotates the drum via a gearbox.

As rotation continues, steel balls inside the drum compartment are lifted up as high as centrifugal force and friction take them before falling back down on the materials.

During this process, a large crushing force acts on the materials, grinding them to finer sizes. The finely ground particles move out of the drum via a classifier. Coarse particles are returned to the mill for further grinding, which forms a so-called closed circuit.
