Industrial Ball Mills: Steel Ball Mills and Lined Ball

Ball Mills Steel Ball Mills & Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late ’s The basic construction of a ball mill.

Wet vs Dry Grinding

Jan 30, There has been a well established “truth” that wet grinding is more efficient than dry grind- ing This should apply to ball mill grinding as well as autogenous grinding It has been earlier shown that the effect of dry ball mill grinding increases considerably, when the fines are efficiently removed from the mill.

Ball Mill

Oleg D Neikov, in Handbook of Non-Ferrous Metal Powders, Tumbling Ball Mills Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale Grinding elements in ball mills travel at different velociti Therefore, collision force, direction and kinetic energy between two or more elements vary.

Ball Mills

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.

The operating principle of the ball mill

The operating principle of the ball mill consists of following steps In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls Then, discharge of ground material performed.

Grinding Media

This leads to a narrower size distribution and significantly less slime compared to ball mills Lower critical speeds of 50 - 65 % and coarser product size (ie 50 mm v 15 mm) results in a lower impact.
