The shovel blade picks up the material and send it between the grinding roller and grinding ring. The ball mill is a horizontal structure. When ball mill works, the rotation of grinding body drives the steel balls inside. The grinding media, steel balls, reach a high point and fall down. The compaction against each other grinds materials into ...

The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding action restricts the volume of feed which passes ...
