Professional FTM limestone raymond grinding mill (miningftm.com) is a new kind of mill, which is invented with great concentration and on the basis of many years of powder processing experiences. This invention starts anepoch of high efficiency and low cost in international mining industry.

Features of Professional Limestone Raymond Grinding Mill

1. Professional limestone raymond grinding mill is vertical and takes small room. It is an independent production system from feeding material to final product.

2. Fineness of final product is even and the passing rate can be up to 99%, which is incomparable by other mills.

3. The transmission device of the main frame uses close gear and pulley, which runs smoothly and stably.

4. The important part is made by qualified steel and wearing parts by high qualified wearable material.

5. As the electric control system is centralized, no people are needed in operating room, and it is easy to maintain

Working Principle of High Efficiency Full Service Raymond Grinding Mill:

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 vertical grinding 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 processof raymond vertical grinding 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 vertical grinding 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.
