Ball mill is a kind of grinding machine, which is the key ball milling machine used after the material has been crushed. It also has a mixing effect. This type of grinding machine has a cylindrical body with spherical grinding mediums and materials.
Numerous grinding balls were obtained from eight major US manufacturers. All balls were nominally 75-mm diam. Steel grinding balls came from 6 manufacturers in 13 different lots, and alloyed white cast iron balls came from 3 manufacturers in 1 lot each. At least three balls selected at random from each lot were evaluated.
(1) Types on the Basis of Cylinder. 1. Short Cylinder Ball Mill: The ball mill with the cylinder length (L) less than 2 times of the cylinder diameter, i.e. the ball mill with L ≤ 2D is short cylinder ball mill, which is usually of single bin structure, mainly used for rough grinding or primary grinding operation, and can realize the wide use of 2-3 ball mills in series.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
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.
