The Working Principle of Raymond Mill Machine

Courtesy of Guilin Mining Machinery Co., LTD.

When the ultra-fine Raymond mill Machine works, the materials to be crushed are added into the machine from the feeding hopper on the side of the machine cover shell. It relies on a roller-grinding device suspended on the main frame to rotate around a vertical axis while rotating itself. Because of the action of centrifugal force during rotation, the grinding roller swings outwards and presses firmly on the grinding ring, so that the shovel picks up the material and sends it between the grinding roller and the grinding ring. As a result, the grinding roller can crush the material by rolling. The process of wind selection: after the material is grinded, the fan blows the wind into the main engine shell, blowing up the powder, sorting through the analyzer above the grinding room and passing the coarse material into the grinding room and regrinding. The fineness conforming to the specifications will enter the cyclone collector along with the wind flow, and after collection, it will be discharged through the powder outlet, that is, the finished product. The air flow is fed back into the fan by the return duct at the upper end of the cyclone collector. The increase of the air volume of the circulating air channel is partly discharged by the exhaust pipe between the fan and the main engine, and enters the small cyclone collector for purification.
