Quartz stone is a mineral resource with very stable physical and chemical properties. It is in the form of massive, coarse-grained, stalactite-like, with a Mohs hardness of 7. Can be widely used in public buildings and home decoration and other fields. The general processing equipment of the mine can only grind various non-flammable and explosive mineral products with Mohs hardness below 6. However, Raymond mill equipment can process and crush mineral products with a Mohs hardness of less than 9.3.
Since its introduction to China for more than 20 years, Raymond Mill has been widely used in the processing of non-metallic minerals. However, with the extensive development of non-metallic minerals in the field of ultra-fine powder applications, downstream companies are increasingly demanding non-metallic mineral products. In particular, there is a higher demand for product fineness. This makes the traditional Raymond mill seem incapable. Shanghai SBM has carried out comprehensive and thorough technological innovation on the traditional Raymond mill based on the ultra-fine powder equipment processing technology that has been mastered for many years. A new Raymond mill has emerged.
The complete set of Raymond mill consists of main engine, reducer, analysis machine, pipeline device, blower, dust collector, jaw crusher, bucket elevator, electromagnetic vibration feeder and electronic control system. The quartz stone material is tightly pressed on the grinding ring under the centrifugal force of the grinding roller, and the material is sent by the blade to the middle of the grinding roller and the grinding ring, crushed into powder under the action of the rolling pressure, and then in the fan Under the action, the powdered material is blown up through the analysis machine, and the material that meets the fineness requirement passes through the analysis machine, and the heavy grinding chamber that does not meet the requirements is continuously ground, and is separated and collected by the material of the analysis machine into the cyclone separator. The exhaust air is separated by an industrial filter cloth to form a powder.
The traditional Raymond Mill has a low yield and fineness, generally below 500 mesh, and the application range of the finished product has great limitations. Moreover, the incidence of mechanical failure is high, and noise and dust are seriously polluted. The finished product of the SBM Raymond mill has a particle size of up to 1000 mesh. The fineness of the finished powder is uniform, and the screening rate is 99%. The electrical system adopts centralized control, and the grinding workshop can basically realize unmanned operation and convenient maintenance. Noise and dust are in line with national environmental requirements.
