Introduction to Raymond Rock Grinder in China

Raymond Rock Grinder in China is one machine introduced from foreign countries. At present, there are many Raymond grinder manufacturers, and the grinding plant is used for all ores and coal powders preparation, such as fine powder processing of raw material ore, gypsum ore and coal. In the powder rock grinding industry, the main development directions of the Raymond mill are reliability, precision, automatic supervision and control. Such measures as controllable silicon power supply, AC variable frequency speed regulating, grease centralized lubrication and vibration reduction can be taken and the devices such as supervision of working conditions and micro automatic control can be equipped.

Working Principle of Raymond Rock Grinder in China

The Raymond Rock Grinder in China crushes and grinds the bulk raw material into the required feeding granularity, after that bucket elevator lifts the material into the storage bin, and then electric vibrating feeder transports it evenly into the grinding chamber where the material is scooped up by shovel blade and grinded between grinder roller and grinder ring, and then the blower blows the air into the grinding chamber from shunt plate and blows the grinded powder into the analysis chamber, the powder is concentrated by rotating analysis impeller that is driven by the speed motor with transmission gear, after the concentration, the large granular material drops back into the grinding chamber and is grinded again, and while the qualified fine powder enters into cyclone powder collector following the air flow.

When the qualified powder separates with air, it is discharged into the final product from the discharging port. In the working process of the host machine, the shovel blade plays the important role. It is in the lower end of the grinder roller and they rotate at the same time when the material is scooped up and thrown into the space between grinder roller and grinder ring thus it shapes litter layer which grinds the material with the pressure force produced by rotating grinder roller so as to achieve the goal of making powder.
