Rock Grinder Mill is widely used to grinded all kinds of materials such as barite, gypsum, limestone, dolomite, feldspar, etc. The powder size of rock grinder mill is from 0.613mm to 0.044mm, some micro fine powder can be 0.013mm.

Rock Grinder Mill consist of main frame, powder classifier, blower, air duct tube, dust catcher, powder collector, etc.

Working principle of Rock Grinder Mill is :

1. Raw material is crushed by jaw crusher to the size required which is suitable for theRaymond Mill (Grinding Mill),

2. Then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feederevenly and continuously into the grinding chamber for grinding mill. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind.

3. After this, the ground stuff are carried by the air from the blower into the powder separator (Analyzer Machine) for screening. The fine powers are blow into the cyclone powder collector and are poured out through the output-powder valve as the final products, and the corase stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.
