Vertical raw mill is a type of industrial equipment used to crush or grind materials into small particles.Vertical roller mills are widely used in the concrete and mining fields, and are also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials.

Application : Cement Plant, Clinker Grinding Unit, Thermal Power Plant

Capacity : 70-720 t/h

Motor Power : 800-2800 kW

Fineness : 80μmR 12-15%

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 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.

Note: mill spectral pattern benchmark

Material medium friction (MF)=0.9~1.0;

Material moisture max 7%;

Refined powder granularity 80μmR 12~15%;

Refined powder moisture 0.5~1.0%;

The concrete mill installed power and technology parameter will be adjusted appropritely basing on the actual material property and requirements of owner;

The above specification also applies to limestone powder mill, and the concrete type selection shall be decided according to material property.
