Raymond mill is widely used in dolomite, limestone, potash feldspar, barite, calcite, talc, marble, fluorite, activated clay, activated carbon, bentonite, kaolin, cement, gypsum, glass, etc. Mohs hardness is not more than 9.3 Grade, non-flammable and explosive mineral, chemical, construction and other industries with a humidity of less than 6% for high-fine powder processing of more than 280 materials. The finished product particle size of the R-type Raymond mill can be adjusted arbitrarily within the range of 80-325 mesh. Some materials can reach up to 600 meshes.

Raymond Mill Working Principle

When the Raymond mill is working, the material to be crushed is fed into the machine from the feeding hopper on the side of the machine cover. It relies on the grinding roller device suspended on the plum blossom frame of the main machine to revolve around the vertical axis, and at the same time, it rotates on its own. The grinding roller swings outwards and is pressed tightly against the grinding ring, so that the shovel blade scoops up the material and sends it between the grinding roller and the grinding ring. The grinding roller achieves the purpose of crushing the material.

After the material is ground, the fan blows the wind into the main frame to blow up the powder, which is sorted by the analyzer placed above the grinding chamber, and the coarse material falls into the grinding chamber for regrind, and the fineness meets the specifications. It enters the cyclone collector with the wind, and is discharged through the powder outlet after being collected, which is the finished product. The air flow returns to the fan from the return air pipe at the upper end of the large cyclone collector. The air path is circular and flows under negative pressure. The increased air volume of the circulating air path is discharged through the exhaust pipe between the fan and the main engine and enters the small cyclone collection. The device is cleaned.

Unique Structural Design of Raymond Mill

Relying on the unique structural design of Raymond mill, it occupies a smaller space area and is more convenient for transportation, installation, operation and maintenance. Moreover, it adopts PLC electrical automation control, which effectively reduces the failure rate and labor cost of the equipment, while achieving High-yield, high-efficiency production, and achieve a good production environment with zero noise and zero pollution. In addition, the grinding fineness of the Raymond mill can be adjusted between 80-800 meshes, and the applicability is more flexible and extensive. On the whole, Raymond mill is the best choice for non-metallic mineral grinding.
