coarse grinding mill

The European version of coarse grinding is mainly suitable for medium and fine crushing of various soft and hard ores whose compressive strength is not higher than 320MPa (megapascal), and is widely used in metallurgy, mining, chemical industry, cement, coal gangue, construction, sand making, refractory materials And ceramics and other industrial and mining enterprises. The European version of the coarse powder mill is mainly composed of the casing, the rotor, the bearing iron and the grate bar.

Coarse grinding mill Performance and Features

1. High capacity, big crushing ratio;
2. Low power consumption, uniform granularity;
3. Mechanical structure is simple, easy to use;
4. Investment costs less, more Convenient Management.

Coarse Grinding Mill Working Principle

The main machine drives the main shaft through the motor and the V-belt, so that the rotor rotates, and the hammer head is stretched around by the centrifugal force generated by the rotation. The qualified crushed materials are discharged from the grate bar with a gap at the bottom, and the unqualified materials are left in the crushing cavity, and are repeatedly acted by the hammer and the bearing iron block until they can be discharged qualified. In order to avoid clogging, the water content of the crushed material is generally not more than 5%.
