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
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
Vertical Roller Mills. Optimization of VRM Operation Do not believe screen values unless you have checked them Continuously change Process Parameters and document results to find Optimum Optimum is highest capacity at lowest power consumption Be sensitive to changes of feed material and adapt parameters Focus on Relevant Process Parameters only Optimize Control Loops
ECUTEC's Atlas Vertical Roller Mills have been developed for more efficient fine grinding of soft to medium-hard materials.. The Atlas is a roller air-swept mill designed for continuous operation with minimum maintenance. The fundamental difference between the Atlas and other table-roller mills is the bearing arrangement for the grinding table which is incorporated into the base of the mill.
