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
The Methods of Increasing the Capacity of Cement Grinding Mill
Cement grinding mills can be produced both dry and wet, and can also be in operations of grinding and drying at the same time. Users are looking for a higher capacity of cement grinding mill in the use of cement mill, thereby reducing the production costs. This article gives you a few tips to increase the capacity of cement grinding mill.

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
