Asbestos means having a high tensile strength, high flexibility, chemical resistance and thermal erosion, electrical insulation and having spinnability silicate mineral products. It is a general term for natural fibrous silicate minerals. Class 2 under the jurisdiction of a total of six kinds of minerals (chrysotile and amphibole asbestos, actinolite asbestos, anthophyllite asbestos, amosite, tremolite asbestos). Asbestos fiber bundle, the fiber bundle is composed by a very long and very fine fibers can be separated from each other. Asbestos having a high degree of fire resistance, electrical insulation and thermal insulation, it is important fire protection, insulation and insulation materials.

Introduce of Asbestos powder process vertical roller mill
Finished Asbestos powder fineness: 47-5 micron (325mesh-2500mesh)
Capacity: 0.4-12T per hour

Models of Asbestos powder process vertical roller mill: HGM80/HGM90/HGM100/HGM100A/HGM125
Input Asbestos ore size: ≤20mm

Working Principle of Asbestos powder process vertical roller mill:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. 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 blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone 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.
Production Line Configuration of Asbestos powder process vertical roller mill:
Consist of crushing machine, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.

Features of Asbestos powder process vertical roller mill:
1. High efficiency
At the status of the same finish fineness and power, its production capacity per hour is twice as much as other jet mill, mixing grinder and ball mill.
2. Long lifecycle of wearing parts
The ring and rollers are forged by special material with high utilization. Under same grinding material and finish fineness, the wearing parts life cycle usually is one year, which is 2-3 times longer than impact mill and turbo mill. The service time can reach 2-5 years if grinding carbonate (calcium carbonate).
3. High safety and reliability
There are no rolling bearings and bolts in grinding cavity, so there are no problems caused by bolts shedding or wear of bearings and seal components.
4. High fineness and flexible adjustment
The final product fineness can be adjusted between 325 meshes and 2500 meshes (47 microns to 5 microns), and the product fineness can reach D97≤5μm.
5. Environment friendly
The application of pulse deduster and muffler alleviate the dust pollution and noise.
