What particle size range does ball mill grinding produce?

Ball mill grinding is one method of crushing ore to an appropriate size fraction. Specifically, ore is put into a large receptacle (a drum) and then it rotates slowly around.

Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Grinding in Ball Mills: Modeling and Process Control

55 known as the distribution function [45, 46]) describes the distribution of fragment sizes obtained after a breakage of particles of size xj.Thus, b1j, b2j,,bnj are the mass fractions of particles in size classes 1, 2,,n after a breakage of particles in size class j. The mechanism of breakage is illustrated in [23] by a diagram shown in Fig. 3.

Grinding Mineral Processing

The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.

efficient at fine separation sizes. However, for middle size particles this process is less efficient. When too much water is added to the process, more middle size particles are produced by the ball mill, so the cyclone overflow allows a lot of these middle size particles to escape the grinding circuit. This
