Raymond Mill is a fine powder milling equipment suitable for high-efficiency closed-circuit circulation in large, medium and small mines, chemical industry, building materials, metallurgy and other industries. The uniformity of the fineness of the various powders milled by the mill can reach 95% of the required fineness, which means that the sieve can reach 95%, and the R-type Raymond mill is a vertical structure and a complete set. Sexually strong from the fast material to the crushing to the finished powder, packaging, can be a self-contained production system.
Raymond Mill uses the advanced structure of its kind. This machine has higher efficiency, lower power consumption, smaller floor space and less one-time investment than ball mill. The grinding roller is tightly pressed on the grinding ring under the action of the centrifugal force, so the grinding roller and the grinding ring are not worn to a certain thickness and the yield and fineness of the finished product are not affected. It can be seen that the grinding ring and the grinding roller have a long replacement period, thereby kicking out the shortcomings of the replacement cycle of the wearing parts of the centrifugal pulverizer. The wind speed of the R-type Raymond mill is circulating in the fan-grinding-cyclone-fan, so the centrifugal pulverizer has less dust, the operation workshop is clean, the environment is non-polluting, and it can fully meet the national dust emission standards.
This machine 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, insulation material. High-fine powder processing of more than 300 materials such as non-flammable and explosive minerals, chemicals, construction and other industries with a Mohs hardness of not more than 7 grades and a humidity of 6% or less. The R-type Raymond mill has a finished grain size of 80- Any adjustment within 325 mesh range, some materials up to 600 mesh.
The structure of the machine is mainly composed of a main machine, an analyzer, a fan, a finished cyclone separator, a fine powder cyclone separator and a duct. Among them, the main body is composed of a frame, an inlet volute, a blade, a grinding roller, a grinding ring and a cover.
During work, the material to be pulverized is fed into the machine from the feeding hopper on the side of the hood, and is revolved around the vertical axis by means of a grinding roller device suspended on the main stand of the main machine, while rotating itself, due to the centrifugal force during rotation, The grinding roller swings outward, pressing against the grinding ring, so that the blade shovel the material to the grinding roller and the grinding ring, and the purpose of pulverizing the material is achieved by rolling rolling of the grinding roller.
