We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.


The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.


Ball mills are fine grinders, have horizontal ball mill and vertical ball mill, their cylinders are partially filled with steel balls, manganese balls, or ceramic balls. The material is ground to the required fineness by rotating the cylinder causing friction and impact.


The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...


Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼" to 1.5". The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...
