Learn More About Raymond mill

Raymond mill is an efficient, energy-saving and environmentally friendly milling equipment, suitable for the processing of a variety of non-metallic mineral materials, with a wide range of particle size adjustment (80-325 mesh, some up to 600 mesh), and high durability (wear-resistant parts have a life of more than one year, and fineness can reach D97≤5μm). It adopts a centralized control electrical system to simplify the operation process and reduce maintenance requirements. At the same time, PLC control reduces noise and pollution, and realizes a low-noise, less-polluting working environment. Raymond mill works under negative pressure, which improves safety and reduces dust pollution. In addition, due to the use of high-performance wear-resistant materials, the long-term operating cost is low, and the one-time investment is small, which helps users to quickly recover costs. The new structural technology adopted has been updated and improved on the basis of the traditional Raymond mill, which has improved efficiency and reduced power consumption, making it occupy an important position in the field of non-metallic ore grinding and processing.

Working Principle

The material is first crushed to the required size by a jaw crusher. The crushed material is lifted to the storage hopper. Through the electromagnetic vibrating feeder, the material is evenly and continuously fed from the storage hopper into the main grinding chamber. The material is rolled and crushed by the grinding roller in the grinding chamber. The grinding roller swings outward due to the centrifugal force generated by the rotation and presses against the grinding ring. The scraper sends the material to the grinding roller and the grinding ring for crushing. After the material is ground, the blower blows air into the main casing to blow up the powder. The analyzer sorts the powder, and the material with too coarse fineness falls into the grinding chamber for re-grinding. The powder with the fineness that meets the specifications enters the cyclone collector with the wind flow, and is discharged through the powder outlet after being collected, which is the finished product. The wind flow returns to the fan from the return air duct at the upper end of the large cyclone collector. The wind path is circulated and flows under negative pressure. The increased air volume of the circulating wind path is discharged through the exhaust gas duct between the fan and the main machine, enters the small cyclone collector, and is discharged into the atmosphere after purification.
