success or failure of the VRM production depends on pressure difference between inlet and outlet, the grain size of the raw material [1, 2]. For VRM the production capacity denotes both the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is ...

Differences between Cement Ball Mill and Vertical Cement Mill Grinding Mechanism. The grinding mechanism of a ball mill is a series of impact and attrition events that occur inside a large rotating drum. The grinding media collide with each other and the material being ground in the drum, creating a large amount of heat.
