I. Ultra Fine Roller Mill Usage and Application

The Super Fine Powder Mill is designed to produce super-fine powder or micro powder of different 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 325-2500 meshes (0.044-0.0055mm).

 II. 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 is 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.

III. Working Principle

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. After ground in the first layer of the dial, the materials fall into the second and third layer and are crushed and ground. 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.
