Raymond Mill

Usage and Application

It is mainly used to pulverize various nonflammable and unexplosive materials less than 9.3-scale Moh’s hardness and 6% humidity, in the industries of glass, rubber, pesticide, ceramic, paint, phosphate fertilizer and paper-making etc. These materials include pencil stone, barite calcite, limestone, marble, manganese ore, iron ore, clay, feldspar, bolus alba, bentonite and so on.

Working Principle

Materials first enter jaw crusher to be crushed to smaller size. Then they are lift to storage room by elevator. Vibrating feeder will feed materials into raymond mill chamber evenly and gradually. After being grinded, the powder will be blowed to cyclone by blower. Then the material will be transferred to storage room through pipes, and then will be discharged as final products. The whole process of raymond mill works in a negative pressure environment. First, through pipes, the air from the blower enters the cyclone collector above the storage room along with powder, and then returns to the blower through return pipe. In the way, air can be recycled. There is a powder locking equipment under the cyclone in raymond mill, which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there. The clean air will be discharged so that environment will be protected.

Feature

1. Wide application scope,can use to crush materials less than 6 moth of hardness.
2. Under the effect of high pressure spring, the fineness of final product is increased greatly.

3. Compared with Jet Milling, the energy consumption is lower.

4. Less investment, high efficiency, recycling fast.

5. Independent system, less Production links, materials less than 25mm can be put into processing directly.

6. No pollution, dedusting effect is completely meet national standards.

7. The sealing effect of grinding roller device is good.
