China factory metallurgy stone raymond Grinder Mill

Raymond mill product description:
After years of practice and continuous improvement, the R-type Raymond mill has become more and more perfect in structure. Therefore, it is widely used in the boring grinding of mineral products in the fields of metallurgy, building materials, chemical industry, mining, etc. It is suitable for processing with a hardness of 7 on the Mohs scale. All kinds of non-flammable and explosive minerals with humidity below 6%, such as gypsum, talc, calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, Bauxite, red iron oxide, iron ore, activated carbon and other 280 kinds of materials, the fineness of the finished product is between 0.198 mm-0.044 mm (80 mesh-325 mesh), through the joint action of the analyzer and the fan, it can meet different users Requirements for use.
The working principle of Raymond mill:
The structure of the machine is mainly composed of a host, an analysis machine, a blower, a finished cyclone separator, a pipeline device, and a motor. The main machine is composed of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, a cover and a motor. Auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc. Users can choose flexibly according to site conditions.
When the Raymond mill is working, the bulk raw materials are crushed to the required feed size, and then the materials are transported to the storage bin by the bucket elevator, and then sent to the mill chamber of the host machine by the electromagnetic vibrating feeder evenly, and enter The material in the mill is shoveled up by the spatula and enters between the grinding roller and the grinding ring to be ground. The blower blows air from the splitter disk into the grinding chamber, and sends the pulverized powder to the analysis room. It is driven by the speed-regulating motor through the transmission device. The rotating analysis impeller is sorted, the large particles of materials fall back to the grinding chamber, re-grind, the qualified fine powder enters the cyclone powder collector of the finished product with the airflow, and is separated from the air and discharged from the discharge port as the finished product. During the operation of the main engine, the blade system plays a very important role. It is located at the lower end of the grinding roller. During the same rotation of the shovel blade and the grinding roller, the material is shoveled and thrown between the rings of the grinding roller to form a cushion layer. The material layer is rotated by the grinding roller to generate an outward squeezing force to push the material Crushing to achieve the purpose of milling.

Performance characteristics of Raymond mill:
1. The whole machine is a vertical structure with a small footprint and strong system. From rough processing of raw materials to conveying to powder making and final packaging, it can form an independent production system.
2. Compared with other mills, the sieving rate is as high as 99%.
3. The main transmission device of the Raymond mill adopts a closed gear box and pulley, which is stable in transmission and reliable in operation.
4. The important parts of Raymond pulverizer are made of high-quality castings and profiles. The craftsmanship and rigorous process ensure the durability of the entire equipment.
5. The electrical system of the pulverizer adopts centralized control with a high degree of automation.
