Industrial big output capacity vertical grinding mill
Industrial vertical grinding mill---Super-pressure grinding mill
Outline of super pressure grinding mill
Super-pressure grinding mill is a high efficiency grinding plant designed by our company after absorbing the advanced technology home and abroad and combining many years practical experience. This series product is suitable for non-flammable and non-explosive materials, with hardness less than 9.3, with moisture less than 6%, such as, barite, limestone, ceramics, slag, gypsum, calcite, quartz, etc. It is available for high fine powder processing of more than 200 kinds of material in mine, chemical industry, construction materials and other industries. The output fineness can be adjustable between 80-1200 mesh.
Working principle of super pressure grinding mill
The motor drives the gear box which turns the mill table. Material falls onto the center of the mill table from the material inlet. At the same time, hot air enters the mill from air inlet, Under centrifugal force effect, the material moves to edge of the mill table going into a ring groove where it is ground by rollers. The ground material is carried up by the high speed air flow at the place of wing ring. The big particle directly falls onto the table to be reground. The coarse material in the air, when passing through separator, due to the effect of revolving rotor, comes back to the mill table to be reground. The qualified fine material goes out of the mill with the air, and is collected in a dust collector as product.
Feature of super pressure grinding mill
1. Low operation cost.
High grinding efficiency, low power consumption. Compared with ball mill, 40-50% the power saving, compared with same capacity Raymond mill, 20-30% the power saving,
2. Low wear and tear.
The space between roller and ring is adjustable, take advantage of the mutual grinding among material, to avoid directly grinding between roller and ring which can extend the service life of spare parts, compared with Raymond mill, 40-60% wearing parts consumption reducing.
3. Little vibration and little shock
The equipment has a device which prevents direct contact between roller hard surfacing and the lining plates on the mill table. Intense vibration is unlikely.
4. Maintenance and wearing parts replacing are convenient.
By turning the movable arm and roller csuper well as oil jack maintenance, the lining plates can be maintained within short time
5. Stable operation
Vibration is little, noise is low, and sealing is good, No dust spillsuper
Movement of oil jack
Roller liftedThe lower cavity of the jack is being filled with oil to lift up the roller. The mill can start up without load. Under this condition, repair and maintenance is also convenient.
Roller pressuredAdopting standard pressure device, adding roller quantity (2, 3 or 4 rollers are available) to ground together when mill capacity increasing, It can be a series of product with many capacity which can meet request of different material and capacity.
