Raymond mill introduction:

The Raymond mill adopts the structure of similar products at home and abroad, and is updated and improved on the basis of Raymond mills in the same industry. The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force, so when the grinding roller and the grinding ring are worn to a certain thickness, the output and fineness of the finished product will not be affected. The replacement cycle of the grinding mill roller and the grinding ring is long, which eliminates the shortcoming of the replacement cycle of the wearing parts of the centrifugal pulverizer. The air flow of this machine is circulated in the fan, mill shell, cyclone separator and fan, so it has less dust than the high-speed centrifugal pulverizer, and the operation workshop is clean and the environment is pollution-free.

Main application scope and suitable materials of Raymond mill

Raymond mill use and scope of use:

Raymond mill is widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass , thermal insulation materials and other non-flammable and explosive materials such as Mohs hardness not greater than 9.3, humidity below 6%, high-fine milling of more than 280 kinds of materials in non-flammable and explosive mining, chemical, construction and other industries. The particle size can be adjusted arbitrarily within the range of 80 to 325 mesh, and some materials can reach 600 mesh. Main structure of Raymond mill: The structure of the Raymond mill is mainly composed of host, analyzer, fan, finished product cyclone, micro-powder cyclone and air duct. Among them, the main engine consists of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring and a cover.

The working principle of Raymond mill:

Main application scope and suitable materials of Raymond mill

The materials to be pulverized are evenly and continuously fed into the grinding chamber of the main engine of the Raymond mill. Due to the centrifugal force during rotation, the grinding roller swings outward and is pressed against the grinding ring. The shovel scoops up the material and sends it between the grinding roller and the grinding ring. The purpose of crushing is achieved due to the rolling of the grinding roller. After the material is ground, the grinding is brought into the analyzer with the circulating air of the blower for sorting. The material with excessive fineness will be re-ground, and the qualified fine powder will flow into the finished cyclone powder collector with it, and will be discharged through the powder outlet pipe. for the finished product. Because there is a certain amount of moisture in the material to be ground in the grinding chamber, heat is generated during grinding, water vapor is evaporated, and the pipes of the whole machine are not tightly connected, and the outside air is sucked in, which increases the circulating air pressure and ensures that the grinding machine works under negative pressure. , The increased air flow is discharged into the dust collector through the residual air pipe, and then discharged into the atmosphere after being purified. Structural features of Raymond mill: 1. Three-dimensional structure, small footprint, strong complete set, and independent production system from block to finished powder. 2. The fineness of the finished powder is uniform.
