HGM series of Three-Ring & Medium-Speed MicroPowder Grinder is a new kind of micro-powder processing equipment, which is invented through more than twenty times experiments and (http://maplered.com) improvements, and (http://maplered.com) based on twenty years of mill manufacture experience while absorbing advanced international machine manufacture techniques.

HGM series of Three-Ring & Medium-Speed MicroPowder Grinder is mainly used in processing non-inflammable, non-explosive, brittle Material (http://g654.org) with hardness below six mohs, such as calcite, chalk, limeStone (http://g603.net) , dolomite, kaolin, bentonite, talc, mica, magnesite, pyrophillite, ceyssatite, barite, gypsum, alunite, Granite (http://tanbrown.org) , fluorite, phosphate rock, kalium ore, float Stone (http://g603.net) , more than 200 kinds of Material (http://g654.org) s.
 
Working Principle:

The motor drives the main shaft and (http://maplered.com) every turnplate through the reducer. The reducer drives dozens of rollers to rotate against race way of ring through pin. Small Material (http://g654.org) s crushed by hammer crusher is transported into hopper by elevator, and (http://maplered.com) then vibrating feeder shall feed Material (http://g654.org) to the central part of upper turnplate evenly. The Material (http://g654.org) falls to circle under the centrifugal force and (http://maplered.com) comes down to raceway of ring to be crushed into powder. After grinded in the first race way, the Material (http://g654.org) goes to the second and (http://maplered.com) third turnplate. The blower inhales the external air into the mill and (http://maplered.com) carries the powder after third turnplate into powder-separator. Turbine in the separator makes the coarse powder drop down and (http://maplered.com) regrinded and (http://maplered.com) the fine powder shall go into cyclone powder collector together with air current and (http://maplered.com) go down through discharge valve as final product; at the same time, air current with a little dusts goes out through blower and (http://maplered.com) muffler after purified by filter.

Capabilities and (http://maplered.com) Characteristics:

Three-Ring & Medium-Speed MicroPowder Mill has high efficiency and (http://maplered.com) low cost. Its capacity is raised by 40% compared with airflow mill and (http://maplered.com) mix mill on the condition that the Material (http://g654.org) s, the drive and (http://maplered.com) 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 (http://maplered.com) turbine mill under the circumstance of same Material (http://g654.org) s and (http://maplered.com) fineness of the final powder.

Usually, its life span is more than one year. There is no rolling bearing and (http://maplered.com) screw in the grinding cavity, so as to avoid the damage to the machine caused by tear & wear of bearing and (http://maplered.com) seals and (http://maplered.com) the looseness of screws. The fineness of powder can reach 5μm with d97 once.
