Crushing mill

It has both the performance advantages of the crusher and the pulverizer. Through the crushing, crushing and grinding operations, the crushing ratio is large, which can meet the user's requirements for 0-3mm coarse sand and coarse powder, and improve the particle size range of the finished product of the mill.

The particle size of the finished product is uniform

With its own grate screen, the stone that meets the particle size requirements can be directly discharged through the grate, and the unqualified stones continue to remain in the crushing cavity for repeated crushing to ensure uniform particle size of the finished product.

Low investment and easy to manage

The mechanical structure is compact, the technological process is simple, the floor space is small, the investment cost is low, and the management saves time and trouble.

Fast maintenance and long use

Equipped with hydraulic adjustment device, the roof can be opened front and rear, maintenance is convenient and fast, and the downtime is reduced; the lining plate is made of high manganese steel, which is resistant to compression and wear, and is durable.


The Coarse Powder Mill is mainly composed of casing, rotor, bearing iron and grate bars. 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%.
