Innovative grinding technologies such as high-pressure grinding rollers (HPGRs) or vertical roller mills (VRMs) have successfully demonstrated their efficiency, performance and durability in other industries, such as coal grinding or cement production for decades.

Cement performance enhancer

cement additive, in addition to acting as a grinding aid, is specifically designed to increase the late-age strength development of cement. MasterCem LS 3590 cement additive modifies the hydraulic properties of clinker used in the production of cement. Grinding efficiency improvement is typically in the 10-15% range vs. untreated cement. Product

Tumbling Mill Working Capacity Influencing Factors

In the tumbling mill working process, the grinding medium plays the role of grinding and impact in the cylinder at the same time. The quality of the finished product depends largely on the grinding medium. The more grinding media added to the cylinder, the more times the material is ground per unit time, and the higher the ball milling efficiency.
