The machine is mainly used in processing powder of mineral materials of metallurgy, building materials, chemical industry, mining, etc. It can grind non-flammable and non-explosive materials with moisture less than 6% such as Feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate rock, iron oxide red, slag, slag, activated carbon, dolomite, granite, iron oxide yellow, bean cake, chemical fertilizer, compound fertilizer, fly ash, bituminous coal, coke, lignite, Ling U.S. sand, gold, red mud, clay, Kaolin, coke, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, muddy green rock, leaf wax rock, shale, purple rock, Diego rock, basalt, gypsum, graphite, insulation material, etc.
1. Machine body and base are connected flexibly without rigid contact.
2. Machine base is of high intensive, ductile cast iron which is efficient in avoiding crack caused by vibration.
3. Reducer made in China has similar performance as Flender of Germany.
4. Elastic sleeve pin sets couplings are adopted between machine body and reducer.
5. High-density blades are adopted on classifier.
6. Frequency conversion control is adopted in the classifier.
7. Bypass powder collector is adopted.
8. Equipments are distributed under same resistance program.
9.Two outlets of powder collector and that of dust collector are distributed within one line.
10. Set maintenance platform.
Large materials are crushed by jaw crusher into required size for mainframe, then the crushed materials are elevated to the hopper by bucket elevator，then to the grinding chamber for grinding by vibrating feeder evenly and continuously. The powder goes upwards with the airflow, after separating by the classifier, those which can meet the fineness requirement enters into the collector through pipes for separating and collecting, and discharged from the discharged valve as finished products. The airflow is sucked into blower through wind recycling pipe at the upper part of cyclone power collector. And the closed airflow circulation system with negative pressure ensures the environmental health of production line site.
