The working principle of Raymond mill

The main pendulum roller mill drives the central shaft to rotate through the transmission device. The upper end of the shaft is connected to the plum blossom frame, and the frame is installed. There is a grinding roller device and forming a swing fulcrum, not only the country revolves around the center, at the same time the grinding roller revolves around the grinding ring. The roller itself rotates due to friction. The lower end of the plum blossom frame is equipped with a blade system, and the position is at the lower end of the grinding roller. During the rotation, the material is shoveled and fed between the grinding roller rings to form a cushion layer, which is caused by the rotation of the grinding roller to generate outward centrifugal force.

 

Raymond mill air separation process: After grinding the materials , the blower blows the wind into the main mill to blow up the powder, which is separated by the analyzer allocated above the grinding chamber, and the coarse material falls into the grinding again. It is reground in the chamber, and the fineness that meets the specifications enters the cyclone collector with the wind flow, and is discharged through the powder pipe after collection, which is the finished product. The air volume is returned to the fan from the return air pipe at the upper end of the large cyclone collector. The air path is circulated and flows under negative pressure for purification treatment.
