US10010889B1 Vertical roller mill Google Patents

A vertical roller mill has grinding rollers which roll over a grinding path of a rotatable grinding table, and a surrounding nozzle ring separation area for conveying and separating gas. A coarse fraction of ground material is entrained in gas upwards in ducts from a location that is below, at, or above the nozzle ring separation area and is transported into an entry to a material separator

Energy-Efficient Technologies in Cement Grinding IntechOpen

Oct 23, 2015 A larger angle of nip draws the material bed into the grinding gap and reduces wear as compared to vertical roller mills. The recirculation of material within a vertical roller mill is very high. The recycle ratios are 15 or more, but it is practically impossible to measure the recycle ratios in a mill operating on the airflow principle
