LSM Ultra-fine Mill

LSM Series three ring ultra-fine grinder mill is used as fine and ultra-fine powder processing equipment, it is mainly used for processing materials which moth’s hardness is under 6 such as calcite, chalk, limestone, white clouds stone, kaolin, bentonite, talc, mica, magnesite, illite, and etc...

Material hardness level will determines the length of the wear parts and the service life of the machine. The motor drive the main shaft and the rings start to rotate through reducer. The rings drive the ring roller orbiting in the grinding ring track.

The electromagnetic vibrating feeder will evenly feed the materials on the bulk tray, then the materials will spare out under the centrifugal force and falling down to grinding track to be crushed, smashed and squeezed.

After primary crushing, the materials will fall down to the 2nd layer and 3rd layer of machine, the High pressure centrifugal fan will suck air into the machine from the outside and bring the crushed-materials into powder selector.

Powder selector will suck qualified powder into collect bins and send back the rough powder back to grinding track to be crushed again.

Features 1. high efficiency and low consumption. this machinery has 40% higher efficiency than jet mill and agitation mill under same situation 2. long service life, wear parts last more than a year. 3. Grinding chamber adopts no rolling bearings, screws. So there is no damage coming from the accidently Shedding of bearing, seals and bolts.

There is no bearing its seals and wearing a screw loose and easy to destroy machinery and other issues. 4.product fineness can reach d97 ≤ 5μm after single run
