How TGM Mill to Work?

Usage of Super Pressure Trapezium Grinding Mill

This equipment is mainly used to grind minerals in the field of metallurgy, construction, chemical industry, mining, etc., materials processed shall be non-flammable, non-explosive, with moh’s hardness below 9.3 and moisture below 6%.

Structure of Super Pressure Trapezium Grinding Mill

The system of Super Pressure Trapezium Grinding Mill is mainly made up of jaw crusher, bucket elevator, electromagnetic vibrating feeder, main mill, classifier, blower, cyclone collector, bag filter and electric control system. The key of this system is the sealed airflow system, composed of main mill, classifier, blower, cyclone collector, bag filter.

Working Principle of Super Pressure Trapezium Grinding Mill

Firstly, large material is crushed into the size specified (powder or small material is no need to be crushed by Jaw Crusher), then transported into the hopper by bucket elevator vertically, and then fed into the main mill by electromagnetic vibrating feeder continuously and evenly.

The ground fine powder in the main mill is carried out by the airflow from the blower, and then separated by the classifier above the main mill. The fine powers are blow into the cyclone collector, where separate with the airflow, and are poured out through the discharge valve as the final products and the rough 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.

Because the stuff contain some moisture, and the heat generated during the grinding process makes the moisture evaporated, what’s more, the pipeline joints are not airtight and therefore the external air is sucked in, all these will increase air-volume in circulation and disturb the circulation balance. To keep the air current balance in circulation can be realized by adjusting the three-way pipeline between the blower and main mill. In this way, the extra air current is channeled into a bag filter which will collect powder carried by the extra air current and then get rid of the extra air current back to the atmosphere after purification.
