Introduction of HGM80 barite micro powder mill:  

It is mainly suitable for ultra-fine powder processing of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6, such as barite, calcite, chalk, limestone, dolomite, carbon black, Kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, gypsum, alum, graphite, fluorite,  phosphate rock, potassium ore and pumice , more than 100 kinds of materials.

The fine powder finished product can be arbitrarily adjusted between 325-3000 mesh, and the output can reach 0.4-45 tons per hour.


Performance and characteristics of HGM80 barite micro powder mill,ultra-fine grinding equipment :

1. High efficiency and low consumption
In the case of the same fineness of the finished product and the same motor power, the output of the jet mill, the agitator mill and the ball mill is more than doubled; the energy consumption is 30% lower .
2. Consumable parts have long service life
The grinding roller and the grinding ring are forged with special materials, which greatly improves the durability. In the case of the same material and finished product fineness, the service life of the wearing parts of the impact crusher and the turbo crusher is 2-3 times longer, generally more than one year; when processing calcium carbonate and calcite, the service life is up to 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
Raymond mills and other coarse grinding products have a fineness of 325 mesh (47 microns), compared to 325 mesh to 2500 mesh (47-5 micrometers). Adjust, and the fineness can reach D97≤5μm at one time.
5. Environmentally friendly cleaning
The dust collector is used to capture dust, and the muffler is used to reduce noise, which is environmentally friendly and clean.
6. Advanced only frequency conversion speed control device
The use of the device is that the processed powder has a more uniform particle size and is convenient to adjust.

Composition and structure of HGM80 barite micro powder mill

HGM80 barite micro powder mill complete set including crusher, bucket elevator, hopper, vibrating feeder, main unit for grinding, classifier, powder collector, pulse dust removal system, high pressure Fans, air compressors, electrical control systems.

HGM80 barite micro-grinding machine , ultra-fine grinding equipment working principle:

After the bulk material is broken into small particles by the crusher, it is sent to the storage bin by the hoist, and then passed through the vibrating feeder and the inclined guide pipe, and the material is evenly sent to the bulk tray on the upper part of the inner turntable of the main machine. When the mill is working, the main motor drives the main shaft and the turntable through the reducer, and the turntable passes through the edge of the roller pin to drive dozens of grinding rolls to rotate and roll in the grinding ring raceway. The material is scattered to the periphery under the action of centrifugal force, and falls into the magic cavity, which is impacted, rolled and ground by the grinding roller in the loop of the grinding ring. It is repeatedly ground into a powder through a three- or four-layer loop. The high-pressure fan draws outside air into the machine through suction and brings the pulverized material into the classifier. The high-speed rotating impeller screens it, and the unqualified coarse powder falls back to re-grind. The qualified fine powder enters the cyclone dust collector with the airflow, and the dust falls, which is discharged from the bottom discharge valve. A small portion 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 instantaneously sprayed from the inside of the filter bag. The dust adhering to it will fall due to the sudden shaking of the filter bag, and the conveyor at the bottom will send the two collected fine powder materials out for the finished product packaging. The filtered clean air is finally removed at the muffler outlet.
