Loesche is launching its new LM-Master for advanced vertical roller mill (VRM) control. This automation solution stabilises the VRM to allow operation with lower vibration. It also optimises mill performance by making accurate control actions several times per minute and offers continuous monitoring of the milling circuit for improved operational
Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed Attrition mill. The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling .
applications of the vertical roller mill for cement grinding are less prevalent. The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative
