The working principle of Raymond mill

Raymond mill is suitable for grinding non-flammable and explosive ores with a Moh hardness of not more than 7 and a water content of 6% or less, such as calcite, potassium feldspar, talc, limestone and ceramics. The finished product of the machine can be adjusted in size from 100 mesh to 325 mesh, and a coarse powder of 50 mesh to 80 mesh can be produced by adding the device.

After the material is fed into the grinding area of the large 6r mill, the material is shoveled by the blade into the grinding belt formed by the grinding roller and the grinding ring. The high-pressure spring is installed in the grinding device to increase the rolling pressure between the grinding roller and the grinding ring by 1.2 times, and at the same time reduce the frequency of the grinding and rolling device swinging back and forth, increasing the stability and significantly improving the working of the grinding machine. effectiveness. Under the action of circulating air, the material that has been ground into powder is precisely selected by the airflow and enters the analytical machine. The non-conforming returning machine is re-grinded. The particles that meet the requirements enter the cyclone collector with the airflow, and the powder is removed. The nozzle is discharged and the airflow is returned to the fan. During the grinding process, an appropriate amount of airflow is circulated inside the machine through the pipeline device, and excess airflow formed by evaporation of water in the material is discharged into the return air duct through the bag filter or the pulse dust collector.

The mill equipment has a complete set of systems. The built-in grading system can complete two processes of superfine pulverization and super-segmentation at the same time. It is equipped with high-efficiency cyclone separator and dust collection system. The complete system is operated under negative pressure and is clean production.
