HGM series ultra micro powder grinding machine is a professional grinding machine for processing fine powder, micro powder, and ultrafine powder. Commonly known as three ring grinding machine, three ring micro powder grinding machine, medium speed grinding machine, and three ring grinding machine. This machine overcomes the shortcomings of traditional industrial Raymond mills in terms of applicability, output, fineness, energy consumption, and service life. It is an ideal replacement product for traditional grinding machines such as Raymond mills and ball mills, and is widely used in industries such as metallurgy, power, chemical, steel, building materials, and coal in China.

　　The general ultra-fine powder mill is mainly applicable to non flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, pigment, clay, alunite, graphite, fluorite, phosphate rock, potassium ore There are hundreds of materials such as pumice, and the fineness of the discharged product can be adjusted within the range of 325 to 2500 mesh.

　　1. Low investment cost. Under the same fineness, it has less investment, lower cost, and shorter recovery cycle compared to airflow mill.

　　2. Under the same fineness and power consumption of the finished product, the output is more than 45% higher than that of the airflow mill and stirring mill.

　　3. Low wear and tear of vulnerable parts, all vulnerable parts are made of high wear-resistant materials, which has a longer service life than ordinary grinding machine equipment.

　　4. The operation of the grinding chamber is safe and reliable, and compared with ordinary grinding machines, the sealing performance is better.

　　5. The finished product has a high fineness, which can reach a range of 325 to 2500 mesh.

　　6. Environmentally friendly and pollution-free. Adopting an efficient pulse dust collector, the entire equipment operates without dust pollution. Equipped with silencers and silencing rooms, it reduces noise and produces according to national environmental standards, playing an environmental role in the surrounding environment.

　　The HGM series ultra micro powder grinder is composed of a main machine, apowder concentrator, a powder collector, a dust collector, a fan, a silencer, a sound insulation room, a crusher, a hoist, a silo, a feeder, and other parts. After the large pieces of material are crushed into small particles by the crusher, they are fed into the silo by the elevator, and then evenly conveyed to
the loose material tray on the upper part of the rotary table through the feeder and inclined guide pipe. When the grinding machine is working, the grinding roller rotates and rolls in the ring. Under the centrifugal action, the material disperses towards the periphery and falls into the grinding chamber, where it is stamped, rolled, and ground by the grinding rollers in the ring.

　　As the high-pressure fan continuously sucks the air inside the equipment,the material after multi-layer crushing is brought into the powder concentrator. The high-speed rotating impeller screens it, and unqualified materials fall back and re grind, while qualified materials enter the cyclone powder collector with the airflow. The dust particles with higher density fall and are discharged by the discharge valve at the bottom to form the finished product. The fine dust with lower density 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 instantly spray from the inside of the filter bag, and the dust adhering to it falls due to the shaking of the filter bag. The conveyor at the bottom sends out the materials collected at two places for finished product packaging.
