20th Granite Grinder

We are involved in manufacturing, exporting and supplying of 20th Granite Grinder in Shanghai, China.
Working Principle
YGM series of high-pressure grinding machines, hanger fastening a roller 800-1500 kg pressure of a high pressure spring. Begin work, around the spindle roller and centrifugal forces at high pressure for the spring and Sichuan, the close ring rolling mill, the rolling pressure under dynamic conditions than the same Raymond Mill is 20%, the yield greatly improved.
When grinding the material into the grinding chamber, by the shovel blade into the ground between the roller and grinding ring rolling, rolling after the powder with the circulating air blower into the analysis machine, with the gas passing into the cyclone powder powder device is finished, large particles behind the re-grinding grain. Circulating air blower to repeat the above process to return, I will enter the bag filter air purification.
When the grinding roller and grinding ring up to a certain wear and tear, adjust the length of the spring pressure to maintain between roller and grinding ring constant grinding pressure to ensure a stable output and fineness.
