What are the requirements for the humidity of the Raymond mill?

Raymond mills are mainly composed of main engine, fan, analyzer, finished cyclone and air duct. The components of the main engine are composed of a blade, a grinding ring, a frame, an inlet volute, and a casing. When the Raymond mill is running, the material enters the machine through the casing. After entering the machine, the grinding roller swings outward and presses against the grinding ring. The blade supplies material between the grinding roller and the grinding ring. Rolling and rolling of the grinding rolls can be used to break and grind the material.

The ball mill equipment consists of a rotating device, a lattice ball mill, two bins, and an external gear transmission. The material enters the warehouse of the mill. There are many different sizes of steel balls in the warehouse. After the cylinder rotates to generate centrifugal force, the steel ball is driven to a certain height, thereby causing heavy impact and grinding on the material. After the material has been coarsely ground through the bin, it enters the next box and is then ground. There is also a steel ball and a flat lining.


Raymond Mill is an energy-saving grinding device. Raymond Mill is not a panacea. He has a certain range of use. Not all ore chemicals can be made with Raymond mills. Raymond mill is used for powders with a humidity below 6% and a hardness below 9.3. It is non-flammable and explosive. Under normal circumstances, the production efficiency of Raymond mill is considerable, but the production efficiency of Raymond mill is not constant. In the actual work, in the normal operation process, master the correct method and better maintenance. Maintenance, mastering certain operational skills and preventive measures will definitely increase the efficiency of the Raymond mill.

In addition to Rayleigh's own factors, some objective factors will have a big impact. Here are four short introductions. Under normal conditions, the higher the hardness, the lower the output, the higher the hardness of the material, the lower the production efficiency of the Raymond mill, and the increased wear of the Raymond mill components. The higher the viscosity of the material, the higher the adsorption capacity, the greater the possibility of not being selected by the wind, reducing the efficiency of Raymond milling.

Material Humidity: Raymond Mill is suitable for products with a humidity below 6%. After grinding, the material with high water content will stick to the inside of the Raymond mill, which will also cause blockage during transportation, which obviously affects the efficiency of the Raymond mill.

Composition of the material: Normal use of Raymond mill can produce fineness between 80-325 mesh. If the material contains more fine powder, it will adhere to the inner wall of the Raymond mill. Here, a vibrating screen is first used to screen the size of the powder suitable for the Raymond milling mechanism.
