Ball Mill
8.3.2.2 Ball mills. 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 Mill Grinding Machines: Working Principle, Types, Parts
A ball mill consists of various components that work together to facilitate grinding operations. The key parts include the following: Mill Shell: The cylindrical shell provides a protective and structural enclosure for the mill. It is often made of steel and lined with wear-resistant materials to prolong its lifespan.
