Vertical Roller Grinding Mill Working Principles:
Driven by the centrifugal force, materials move evenly to the edge of the grinding table, and they are grinded by the rollers when going through the rollers’ track. Bulk materials are crushed, while fine materials form material bed after being squeezed and experience intergranular crushing. Grinded materials move on to edge of the grinding table until being taken away by strong airflow at the wind ring, in which larger materials fall to the grinding table by gravity and reground. The others enter the separator being graded. Under theinfluence of separator blades, materials that do not meet fineness requirements return to the grinding table to be grinded, while the standard ones go into dust collector through the pipes and are discharged as finished products from the discharge device. Irons and other impurities, which cannot be lifted by the wind for weight, move together with materials to the edge of grinding table and fall to the lower cavity, and then they are scraped into the slag discharge opening by stripper plate which is fixed at the bottom of the grinding plate and discharged out of the machine.
