In addition, the processing capacity of the rod mill is larger than that of the ball mill of the same specification. The overflow, end peripheral discharge and center peripheral discharge are the three main types of rod mill, while only the wet overflow type rod mill is usually used as the pre-grinding equipment in the cement plant. In order to ...

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.  Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

Working Principle & Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the ...
