The principle of operation of the ball mill, the basic pulverizing device, was already known 150 years earlier; the prototype of the modern mill was invented in the 1870's. Methods of pulverization include crushing, impact, and grinding; compressive strain and shear are very important in these processes.

Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a …
Generally, the diameter of a steel ball is between 20mm and 125mm. Among them, small steel balls are 40mm or 60mm, medium balls are 80mm, and large steel balls are 100mm or 120mm. The diameter of super large balls is 130mm to 150mm. Theoretically, when the filling amount of steel grinding balls in the cylinder of the ball mill is 40%, the ball ...

crusher, roll crusher, hammer mill and ball mill into smaller or finer particles is called as size reduction [2-3]. The principle of attrition and impact is mainly used here. The process of size reduction, also known as comminution or diminution or pulverization is chiefly achieved by two methods – precipitation and mechanical.
