Application of Professional Limestone Raymond Grinding Mill

Professional limestone FTM raymond grinding mill is made up of main frame, powder classifier, pipe devices and blower, and it can be equipped with jaw crusher, bucket elevator, vibrating feeder and electrical generator. After being crushed into the desired size, the materials are sent to the copper by a bucket elevator, and then evenly and continually to the grinding room by the vibrating feeder. With the centrifugal force, the rollers are swinging outward and press the rings closely. The materials are scope up by the shovels to the room between the rollers and the rings and crushed. The fine powder is bowed to the powder separator by the blower to be classified, and the coarse materials fall to the grinding room and the qualified powder are sent to powder concentrator and then discharged through powder pipe as the final product. As the moisture in the materials is evaporated because of heat caused in the process of grinding and the interface is not close, the air pressure inside is high, in order to ensure that the mill works under negative pressure, the air increased is discharged outside after being purified through bag filter.

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.
