Longyi Ultra Fine Vertical Roller Mill/ball Mill/ Ring Roller Mill Machine for Stone

Longyi ultra-fine grinding machine is perfect for nonmetallic materials with hardness less than 6 in Mohs's scale and humidity less than 6 percent such as kaolin, limestone, basalt, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite and so on.


Ultra-fine grinding machine, the granularity (or final size) of the finished products can be freely adjusted between 325-3000meshes (0.045-0.0057mm), and the capacity (ton/hour) ranges from 0.4T/H to 14T/H depending on the final size and the grinding materials.

The whole set ultra-fine grinding machine consists of
1). Hopper, belt conveyer
2). Main unit, classifier, bag impulse dust collector, screw conveyer
3). High pressure positive blower, air compressors and electrical control systems.
 
Working Principle of ultra-fine grinding machine
The crusher will crush the big materials into small ones, and then the elevator will send them to the hopper.
The belt conveyer will send the materials to the middle of first dial evenly.
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.
The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings.
The high pressure centrifugal blower will inhale air from outside and bring the crushed materials to classifier.
The rotating turbo in the powder collector will make the coarse granule return to the mill and be grinded, while the fineness will mix with the air and go into dust collector chamber and be discharged in the discharge bin, which is at the bottom of it.
The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.

Features of Longyi ultra-fine grinding machine
1. The ultra-fine grinding machine is of high efficiency (twice as much as jet mill, mixing grinder and ball mill)
2. The spare parts of ultra-fine grinding machine can serve much longer time (2-3 times longer than that of impact mill or turbo mill.)
3. With our patented classifier, we can classify the powder at one time. 
4. The ultra-fine grinding machine are characterized by high fineness (final size: 325-3000 mesh, D97<5 micron)
5. Environment-friendly.
