CHAENG GRMR raw material vertical mill is a kind of new high efficiency, energy saving and environment friendly grinding equipment specially for cement raw material. Capacity :30-720 t/h Power :17-20 kWh/t Finished fineness :80 μmR 12-15% Process introduction The GRMR raw material vertical mill of CHAENG is a kind of new high efficiency, energy saving and environment friendly grinding equipment specially for cement raw material grinding system in cement plant. Its output can reach 720 t/h, power consumption is 17~20 kWh/t. It has the advantages of high grinding efficiency, low power consumption, low noise, and little dust pollution, can meet the requirements of 300-10,000 TPD cement production line. When it works, raw materials are fed in evenly by the feeder at the bottom of the hopper, then lifted to appropriate height by the bucket elevator, then sent into the mill through feeding pipe to be grinded , the grinded materials are brought into the powder classifier by the hot air generated by the hot air stove, at the same time, the materials are dried and classified , the unqualified materials fall down to be regrind, qualified fine powders are sent into powder collector , and then transported to the storage by the conveyor.
