Details of this product

Coal Mining Machine

        
        

The Coal Mining Machine is mainly suitable for the ultrafine powder processing of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6, such as calcite, chalk, limestone, dolomite, carbon black, kaolin and bentonite. , talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alum, graphite, fluorite, phosphate rock More than 100 kinds of materials such as potassium ore and pumice, the fine powder finished product can be arbitrarily adjusted between 325-2500 mesh (47-5 microns), and the output can reach 325-2500 kg per hour.

        
        

Coal Mining Machine structure

        
        

The complete configuration of Coal Mining Machine includes hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-grinding host, frequency classifier, double cyclone dust collector, pulse dust removal system, high pressure fan, air compression Machine, electrical control system.

        
        

How Coal Mining Machines work

        
        

During operation, the main motor of the Coal Mining Machine drives the main shaft and the turntable through the reducer, and the roller pin on the edge of the turntable drives dozens of grinding rolls to roll in the grinding ring raceway.

        
        

The bulk material is broken into small particles by a hammer crusher and then sent to the storage bin by the hoist, and then passed through the vibrating feeder and the inclined feeding pipe to uniformly feed the material to the bulk disc of the upper part of the turntable.

        
        

The material is scattered to the circumference of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring of the Coal Mining Machine. It is impacted, rolled and ground by the ring roller. After the processing through the three-layer loop, it becomes powder, and the high-pressure fan passes through the suction. The action draws outside air into the machine and brings the pulverized material into the classifier.

        
        

The rotating impeller in the classifier re-grinds the coarse material, and the fine powder that meets the requirements enters the cyclone dust collector with the airflow and is discharged from the lower discharge valve, and the airflow with a small amount of fine dust passes. The pulse dust collector is purified and discharged through a fan and a muffler.

        
        

Product advantages of Coal Mining Machines

        
       

 1. High efficiency and energy saving

        
       

 The Coal Mining Machine is more than twice as high as the flow mill, the agitator mill and the ball mill in the case of the same fineness of the finished product and the same motor power.

        
       

 2. Consumable parts have long service life

        
        

The grinding roller and grinding ring of the Coal Mining Machine are forged by special materials, so that the utilization degree is greatly improved. In the case of the same material and finished product fineness, the wear life of the impact crusher and the turbo crusher is 2-5 times longer, generally more than one year. When processing calcium carbonate and calcite, the service life can reach 2 -5 years.

        
        

3. High safety and reliability

        
       

 Since there is no rolling bearing or screw in the grinding cavity, there is no problem that the bearing and its sealing member are vulnerable, and there is no problem that the screw is loose and the machine is destroyed.

        
        

4. High product fineness

        
        

The fineness of the Coal Mining Machine can reach D97≤5μm at one time.

        
       

 5. Environmental protection, cleaning

        
        

The Coal Mining Machine uses a pulse dust collector to capture dust, and uses a muffler to reduce noise. It is environmentally friendly and clean.
