Usage and Characteritics of the Raw Material Mill

This series of products is mainly used for grinding the cement raw materials, also applies in the metallurgical, chemical, power and other industrial and mining enterprises to grind all kinds of ores and other grind-able materials. The raw materials mill can not only be used in the dry method production but also wet method production. It can also be used in the process of simultaneous grinding and drying job. open stream grinding is suitable too, The raw mill drive form the edge of the drive, compact structure, small footprint. Thus save user investment. Raw mill big end caps, end caps and hollow shaft for the overall casting. In the end caps and discharge system uses a unique streamlined design, reduce the ventilation resistance, increasing the effective volume, easy to discharge mill output. Raw mill for a single-chamber structure, grinding lined plate combination of design, different for different stages of the raw mill liner structure, greatly improving the efficiency of grinding. Raw mill work pressure is negative pressure, to effectively prevent the occurrence of the phenomenon of the powder leakage. Drying hot air is the introduction of high-temperature exhaust gas of the kiln tail wind, insulation measures raw mill, material drying capacity is 6% to 8%. Raw mill electrical control reserve DCS interface to meet the needs of users centralized control.

Application field:
the raw
material mill is widely used in building materials, metallurgy, electric
power , chemical and the other industries for grinding (drying and grinding)
cement raw materials and other materials.

Classification and characteristics of this machine:(1) the ordinary raw
material mill's grinding system is suitable for small and medium-sized,
generally used for circuit grinding system outside the mill the powder. (2) air
swept mill. air swept mill is characterized by short, coarse, and out of the
compound by the air shaft journal, the compartment plate grate seam between
drying the warehouse and grinding positions area the grinding tail no discharge
grate plate , so small ventilation resistance, the wind speed of the grinding
positions is up to 5m / s and above, it is possible to enter a large amount of
hot air, and thus the drying ability. (3) Tail discharge ascension cycle
grinding . The difference between Tail discharge ascension cycle grinding and
air swept mill is that the materials grand are processed by the storage house
end , discharge by the mechanical method, and then sent to the classifying
machine by the elevator, the coarse materials are conveyed back to the mill for
the recycle grinding.
