Ring Roller Micro Powder Mill

Usage and Application
CZM ring roller micro powder mill is designed to produce super-fine powder for hundreds of non-flammable and explosive materials with hardness less than 6 in Moh’s scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment and so on. The granularity of the end products is 200-2500 meshes.

Features
High-efficiency and low consumption
With the same fineness of end products and motor power, its output is two times higher than that of Jet Mill, Mix Mill, and Ball Mill.
Quick-wear parts with longer working life
The grinding rollers and rings are made of special materials. Generally, their work life is more than one year and it could be as long as two years when processing calcium carbonate.
Security and Reliablity
Because there are no rolling bearing and bolts in the grinding chamber, the problems of easily damaged bearings and sealings as well as machine damage due to the bolts looseness are avoided.
Cleansing and Environment Protection
The adoption of pulse dust collector and muffler reduces the industrial dust pollution and noise, which reaches the National Standard.

The motor of main equipment drives the main shaft and dial through reducer, and the dial drives numbers of rollers moving in the ring channels via pins. After being crushed by hammer crusher, big materials become small ones and they are sent to the hopper by elevator. The electromagnetic vibrating feeder sends them to the middle of first layer of dial evenly; the materials will be driven to the edge of dial by centrifugal force and fall into the ring channels and are pressed, crushed and ground by the grinding rings and rollers. The material is crushed in the first layer and then falls into the second, third and fourth layers to continue to crush. The high pressure centrifugal blower inhales air from the outside and blow the materials from the third layer to powder classifier. The rotating turbo in the powder classifier makes the coarse materials return to the mill and reground, while the fine powder mixed in the air goes into the cyclone collector and is discharged from the bottom via discharge valve. The air with very little powder is purified by pulse dust catcher and discharged by blower and muffler.
