Jan 07, 2015· ~ Nael Shabana 20104~ 1.0 Definition of Ball/ Tube Mill: Ball or tube mills are rotating steel cylinders where size reduction of the mill feed is performed by motion of the grinding media. Rotation of the mill cylinder raises the pile of mill feed and grinding media to an optimum high, necessary for grinding operation.

Ball mill  Wikipedia
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill ...

Calculation of circulating load of a grinding mill  Henan ...
We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
