What is the overall structure of Shanghai Raymond Mill? The overall structure of Shanghai Raymond Mill is composed of main engine, analyzer, pipeline device, blower, cyclone separator, jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control motor and so on. The main machine of the Raymond mill is composed of a frame, an imported volute, a shovel, a grinding roller, a grinding ring, a casing and a motor.

working principle
When working, the material to be crushed is fed into the machine from the hopper on the side of the casing, and rotates around the vertical axis through the grinding roller device suspended on the plum blossom frame of the main machine, and at the same time rotates itself. Due to the centrifugal force during the rotation, the grinding roller swings outward and presses on the grinding ring, so that the shovel scoops up the material and sends it between the grinding roller and the grinding ring, and the grinding roller rolls to achieve the purpose of crushing the material.

The overall structure of Shanghai Raymond mill
The overall structure of Raymond mill is composed of main machine, analyzer, pipeline device, blower, cyclone separator, jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control motor and so on. The main machine of the Raymond mill is composed of a frame, an imported volute, a shovel, a grinding roller, a grinding ring, a casing and a motor. The whole working process of Raymond mill (material grinding process): After the large material is crushed to the required particle size by the jaw crusher, it is sent to the storage hopper by the elevator, and then sent to the main mill by the vibrating feeder for uniformity. , Quantitative and continuous grinding, the ground powder is taken away by the airflow of the fan. After grading by the analyzer, the fine powder enters the cyclone collector through the pipeline with the airflow, and after being separated and collected, it is discharged through the powder pipe to obtain the finished powder. The air flow is sucked into the blower by the return air pipe at the upper end of the large cyclone collector. The entire airflow system of the machine is closed and circulates under positive and negative pressure.

In the mill, because the material to be ground has a certain water content, the heat generated during grinding will cause the gas in the mill to evaporate, changing the air flow rate, and the loose connection of all the pipelines of the whole machine will cause the outside gas to be sucked in, which increases the circulation. Airflow volume. Therefore, the balance of the air flow is achieved by adjusting the excess air duct between the fan and the main engine, the excess air is introduced into the small cyclone collector to collect the fine powder brought by the excess air, and then the discharged air passes through the upper exhaust of the small cyclone collector The tube is discharged to the atmosphere or is directed to a dust collector to clean the exhausted air.

What substances are suitable for Shanghai Raymond Mill
Raymond mill is widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation Fine powder processing of more than 300 kinds of materials in non-flammable and explosive minerals, chemical industry, construction and other industries with a Mohs hardness not greater than 7 and a humidity below 6%. The particle size of the finished product can be adjusted arbitrarily within the range of 80-400 mesh. The material height can reach 500 mesh.
