Working Principle

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.
