High Strength Grinding Mill

Product Introduction

High strength grinding mill machine is suitable for the processing of more than 280 kinds of materials. Such as barite, limestone, ceramics, slag, which Mohs hardness is no more than 9.3, humidity is less than 6%. Suitable for non-flammable and explosive mines, metallurgy, chemical industry, building materials, and other industries.

The particle size of finished products can be adjusted in the range of 80-425 mesh (the finest 1000 mesh). Through the special device added in the machine, it can produce 30-80 mesh coarse powder.

Working Principle

In the high strength grinding mill machine, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. After starting work, the grinding roller rotates around the main shaft, and under the action of the high-pressure spring and the centrifugal force, it is pressed against the grinding ring, and the pressure is 1.2 times higher than that of the Raymond mill under the same dynamic condition, so the output is greatly improved. When the material to be ground enters the grinding chamber, it is shoveled by the blade and sent to the grinding roller and the grinding ring for rolling. After rolling, the powder is brought into the analysis machine along with the circulating air of the blower, and the qualified fine powder enters the cyclone powder collector as the finished product, and the large granular material falls back to the regrind.

The circulating air is returned to the blower and the above process is repeated, and the residual air is purified by the bag filter. When the wear of the grinding roller and the grinding ring reaches a certain level, the length of the high-pressure spring is adjusted to maintain a constant rolling pressure between the grinding roller and the ring, which ensures a stable output.
