YGM Raymond mill is high pressure grinding mill composed by main grinding machine, fineness analysis machine, blower, cyclone, bag dust collector and connecting air duct. According to user needs, FLAMCO machinery could supply jaw crusher, bucket elevator, vibrating feeder, electric control cabinet and other auxiliary equipment. How does YGM raymond mill machine work? In YGM raymond mill frame, a 1000-1500kg high pressure spring is fixed to the roller suspender. After the grinder is put into effect, the ring affected by the high pressure spring and centrifugal force. And its rolling pressure is 1.2 times higher than that of the Raymond grinder under the same power condition and the output is raised to higher degree. When materials loaded into the grinding cavity. It is shoveled into the space between the roller and the ring for grinding. The being grinded powder is routed to the classifier along the circulation wind of the blower. Qualified fine powder is guided to the cyclone collector as final product and large size powder falls back to the grinder for regrinding. There is a powder locking equipment under the cyclone in raymond vertical grinding mill , which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there. The clean air will be discharged so that environment will be protected.
