High-Strength Grinding Mill-FTM Machinery

Brief Introduction

High strength grinding mill is a new type of grinding mill introduced by FTM. High strength grinding mill is suitable for crushing barite, limestone, ceramics and slag, with a Mohs hardness of not more than 9.3, and a humidity of 6% or less in the fine powder processing of non-flammable and explosive mines, metallurgy, chemicals, building materials, and other industries. The finished product size is adjusted in the range of 80-425 mesh (the finest 1000 mesh). A 30-80 mesh coarse powder can be produced by adding special equipment inside the machine.

Currently, hot sale types in the market are high strength 96, high strength 95, high strength 93, high strength 86, and high strength 83.

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.
