1. High efficiency and low consumption: Under the condition of the same finished product fineness and motor power, the output of HGM80 rock micro powder mill is more than twice that of air flow mill, stirring mill and ball mill, and the energy consumption is 30% lower.

2. Strong durability: The grinding roller and grinding ring are forged with special materials, and the durability is greatly improved. Under the condition of the same material and finished product fineness, the service life of its wearing parts is 23 times longer than that of impact crusher and turbine crusher, generally more than one year; when processing calcium carbonate and calcite, the service life can reach 25 years.

3. Adjustable fineness: The finished product fineness that can be processed by this micro powder mill can be adjusted arbitrarily between 325 mesh and 2500 mesh (475 microns), and the fineness can reach D97≤5μm at one time, meeting the fineness requirements of different users.

4. Environmental protection and cleanliness: The pulse dust collector is used to capture dust, and the muffler is used to reduce noise, which is environmentally friendly and clean.

5. Stable structure: Because there are no rolling bearings and screws in the grinding chamber, there is no problem of easy damage to the bearings and their seals, and there is no problem of loose screws that damage the machine.

 

 

 

After the large pieces of material are crushed into small particles by the crusher, they are sent to the storage bin by the elevator, and then through the vibrating feeder and the inclined guide pipe, the material is evenly sent to the bulk material plate on the upper part of the turntable in the main machine. When the mill is working, the main machine motor drives the main shaft and turntable to rotate through the reducer. The turntable drives dozens of grinding rollers to rotate and roll in the grinding ring raceway through the roller pins on the edge. Under the action of centrifugal force, the material is scattered to the periphery and falls into the grinding chamber. It is impacted, rolled and ground by the grinding rollers in the ring of the grinding ring. After repeated grinding in three or four layers of rings, it becomes powder. The high-speed rotating impeller screens it, and the unqualified coarse powder falls back to be re-grinded, while the qualified fine powder enters the cyclone powder collector with the airflow, and the dust falls and is discharged from the discharge valve at the bottom as the finished product. A small part of the fine dust enters the dust collector with the airflow and adheres to the surface of the filter bag. The pulse valve controls the high-pressure airflow to be ejected instantly from the inside of the filter bag, and the dust adhering to it will fall due to the sudden shaking of the filter bag. The conveyor at the bottom sends the fine powder materials collected from the two places out for finished product packaging. The clean air after filtering is finally discharged at the outlet of the muffler.

HGM80 rock micro powder mill is widely used in mining, metallurgy, chemical industry, building materials, coatings, inks, papermaking, plastics, rubber, medicine, food and other industries. It can be used to process calcium carbonate, calcite, talc, kaolin, graphite, carbon black, white carbon black, clay, bentonite, mica and other materials.

 

 

1. Before use, check whether all operating links of the machine are normal, including electrical cabinets, circuits, material cleaning, etc.

2. When starting up, the machine should be operated in sequence, and the main machine should be turned on for empty running first to avoid stopping the machine when there is material in the main machine and it has not been produced.

3. If the machine stops automatically, the power is off, or it feels like it cannot be pulled, it should be stopped and checked immediately, and never forced to start.

 

HGM80 rock micro powder grinding mill is widely used in many industries due to its high efficiency, low consumption, durability, adjustable fineness, environmental protection and cleanliness.
