Size matter - when you need it to Capacity requirements for new cement and power plants and grinding units are consistently increasing. Over recent decades, continuous advances in manufacturing processes and design principles have helped us to produce reliable vertical roller mills of ever-larger size and potential capacity.
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
