Vertical Roller Mill Production Line mainly consists of the grinder, dust collector, hot air stove, bucket elevator, feeder, hopper etc. 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
The rollers are made with the toughest material, offering increased longevity and efficient raw and cement grinding. This vertical roller mill uses a hydro-pneumatic system to press its grinding rollers against the material bed on the rotating grinding table. Complete size range to fit your grinding needs.
Cement raw material has been almost exclusively ground in roller mills vertical air-swept grinding mills since the sec-ond half of the 20th century. Loesche was and is the pio-neer of this technology. Hundreds of Loesche mills have been used in the cement industry across the world to the present day. They operate with two, three, four and six roll -
