Raymond mill is suitable for the preparation of various kinds of mineral powder and coal powder. After years of practice and continuous improvement, its structure has become increasingly perfect. It has the advantages of high efficiency, low energy consumption, small floor area, less capital investment and environmental pollution-free. It is reliable and popular. The following is a complete analysis of the working process of Raymond mill.
1. Working principle
The main machine of Raymond mill consists of frame, grinding roller, grinding ring, blade, air inlet volute, cover and motor. Through its structure, we first see how its main engine works: the working process of Raymond mill main engine is to drive the central shaft to rotate through the transmission device, the upper end of the shaft is connected with a plum blossom frame, and the frame is equipped with a grinding roller device and forms a swing fulcrum. While the grinding roller rotates around the grinding ring, the grinding roller itself rotates due to friction. The lower end of the quincunx frame is equipped with a blade system, which is located at the lower end of the grinding roller. During the same rotation of the blade and the grinding roller, the material shovel is thrown between the grinding roller and the grinding ring to form a cushion layer. The material layer is crushed by the outward centrifugal force (extrusion pressure) generated by the rotation of the grinding roller, so as to achieve the purpose of pulverizing
The whole working system of Raymond mill includes jaw crusher, blower, analyzer, pipeline device, finished product cyclone separator, electromagnetic vibration feeder, electric control motor, etc. after the large pieces of materials are crushed by jaw crusher to the required particle size, they are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the main machine for grinding uniformly and quantitatively by the vibration feeder The powder is taken away by the air flow of the fan. According to the classification of the analyzer, the fineness powder flows through the pipeline into the large cyclone collector for separation and collection, and then is discharged through the powder pipe, which is the finished powder. The air flow is then drawn into the blower by the return air pipe at the upper end of the large cyclone collector. The whole air flow system of the machine is closed cycle and circulates under the positive and negative pressure.
