(1) Low investment cost. With the same products' fineness and generator power, it has low investment cost, short return period and twice more output compared with the airflow mill, stirring mill or ball mill.
(2) High powder output. With the same fineness and power consumption, its powder output is more than the airflow mill or stirring mill by 45%.
(3) Low wear and long service time of wear parts. All the wear parts are made of national anti-friction material. Their service life is longer than that of the wear parts of ordinary mill equipment. Generally, they can be used for more than one year.
(4) High security and reliability. The operation which is inside of the grinding chamber is safe and reliable. Compared with an ordinary mill, there is not rolling axletree or screws, so there is no problem of wear of the axletree and other sealed parts, and it avoids the problem that the machine is damaged due to loosen screws.
(5) High fineness of finished product. The final fineness can reach d97≤5μm through one-time processing.
(6) Environmental protection. It adopts an efficiency pulse dust collector, so there is no dust pollution in the complete operation process. In addition, it is equipped with a muffler and sound proofing room so that the pollution and noise can be reduced in accordance with the environment-protection standard, and surrounding environment is protected.

Working Principle:
The main motor drives main axle and every layer rotating by reducer. Dail drives numbers of rollers rolling and rotating in the ring by pintles.
Big materials are crushed into smaller particles by hammer crusher. Then they are sent to store house by elevator. The electro-magnetic vibrating feeder sends the materials evenly to the middle of the upper dial. Under the function of the eccentricity, the materials scatter to the side of the circle and fall into the ring to be pressed, crushed and milled into pieces by rollers. After the first crush, materials fall into the second and the third layer. The pumping of the high-pressure centrifugal blower put the outside air into the machine. The coarse powder will be brought into the classifier.
The rotating turbine in the collector makes the coarse particles fall back for regrinding. The fine particles will come into the cyclone collector with the airflow and discharged by the discharging valve on the bottom of the collector. They are the final products. The airflow with little dust will be discharged through blower and muffler after being purified by the cyclone collector.
1.HGM Micro Powder Mill can be used to grind calcite
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. Calcite is a common constituent of sedimentary rocks, limestone in particular, much of which is formed from the shells of dead marine organisms. Calcite powder is widely applied in artificial stone, man-made floor tiles, natural rubber, synthetic rubber, glass, pharmaceuticals, paints, inks, cables. HGM micro powder mill plays an important role in grinding calcite.
2. HGM Micro Powder Mill can be used in paper making industry
Stone paper has been a hot topic for a long time. In order to do so, the grinding equipment is needed. Stone paper required very high fineness, which means the stone powder has to reach micron size. The most suitable equipment for stone-paper-making is our HGM Micro Powder Mill. It is of low investment cost, high security and reliability, high fineness of finished product and so on.
3. HGM Micro Powder Mill is used in bauxite grinding
Bauxite mine is actually kind of ore minerals collectively formed mainly by gibbsite, a boehmite or a diaspore which can be used in the industry. Bauxite mine can be used widely in many industries among which the most important is to be used for refining aluminum in aluminum Industry, refractory and abrasive materials, and raw materials for high alumina cement. The quality requirements to bauxite mining vary according to their different applications. It’s very important for bauxite mining and bauxite crushing or bauxite grinding with high efficiency. HGM Micro Powder Mill is a suitable equipment for bauxite grinding.
