Micro Powder Processing equipment is a new type of mill for making super fine powder through more than 20 times of test and improvement. The fineness can reach to 0.006mm; Micro Powder Mill is mainly used for processing gypsum, calcspar, talc, and other materials used in painting, pigment and cosmetics industry. Compared with jet mill, it is economic-cost, high-capacity, and the spare parts just need to exchange once a year; the bag filter is added to protect the environment.
Working Principle:
The motor drives the main shaft and every turn plate through the reducer. The reducer drives dozens of rollers to rotate against race way of ring through pin. Small material crushed by crusher is transported into hopper by elevator, and then vibrating feeder shall feed material to the central part of upper turn plate evenly. The material falls to circle under the centrifugal force and comes down to raceway of ring to be crushed into powder. After grinded in the first race way, the material goes to the second and third turn plate. The blower inhales the external air into the mill and carries the powder after third turn plate into powder-separator. Turbine in the separator makes the coarse powder drop down and regrinded and the fine powder shall go into cyclone powder collector together with air current and go down through discharge valve as final product; at the same time, air current with a little dust goes out through blower and muffler after purified by filter.
Advantage and Characteristics:
HGM Micro Powder Processing equipment has high efficiency and low cost. Its capacity is raised by 40% compared with airflow mill and mix mill on the condition that the materials, the drive and the fineness of the final powder are the same. The life span of tear & wear parts is more than that of straight impact crusher and turbine mill under the circumstance of same materials and fineness of the final powder. Usually, its life span is more than one year. There is no rolling bearing and screw in the grinding cavity, so as to avoid the damage to the machine caused by tear & wear of bearing and seals and the looseness of screws. The fineness of powder can reach ≦5μm with d97 once
