Ball mill
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis.

Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum Ball Mill an overview ScienceDirect Topics

Ball Mill (Ball Mills Explained) saVRee saVRee
A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or Ball Mill SpringerLink

Ball Mill, Construction, Working Principle, Application,
Ball mills produce 1 to 50 ton/h power of which near about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batch-operated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.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. 2.What is Ball Mill How Many Types of Ball Mills M&C
