### Industrial Ball Mills: Steel Ball Mills and Lined Ball Mills

The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and the cylinder is put into rotation via an external drive causing the media to roll, slide and cascade.

on the discussion, the higher the speed of the ball mill rotation, the wider the range of size separation. The coarse stones at higher speed can turned into smaller powder which can be reached until sieve 125 µm. The Meshes of larger aperture should be used in sieving to obtain a complete curve of particle size distribution. Thus, we can conclude that the objective of the

the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application. The critical speed of a ball mill is calculated as 54.19 divided by the square root of the radius in feet. The rotational speed is defined as a percentage of the critical speed. Smaller diameter mills

The critical speed of rotation is the speed (in rpm) at which an infinite-ly small particle will cling to the inside of the liners of the mill for a complete revolution. (1) CS = 43.305 √Mill Diameter where CS is the theoretical critical speed of rotation, and is the mill speed, rpm; Mill diameter is the nominal inside diameter of the mill, m.
