Stone Grinding Mill

1. The whole structure of Raymond Mill machine is mainly including the host, analysis machine, plumbing fixtures and the blower, according to user needs, it can be equipped with crusher, elevator, electromagnetic vibrating feeder, electric control cabinet etc.

2. After materials crushed to the desired particle size, enter into the storage hopper by the elevator, and then through vibrating feeder enter into grinding chamber of Raymond mill uniform continuously.

3. Due to the centrifugal force when rotating, the rollers swings outward, pressed on the grinding ring, shovel blade scoop up materials, then sent them between grinding roller and grinding ring, due to the grinding roller roller rolling to achieve crushing purpose.

4. After grinding material, the powder along with the circulating air which made by blower, is brought into the analysis machine for sorting, coarse material will regrind. Qualified powder along with the air enters into finished product cyclone powder collector, then discharge powder tube, that is finished product.

5. In the grinding chamber of Raymond mill, because there are certain moisture in the grinded material, when grinding, it will generate heat, moisture evaporates, and the pipe interface of the whole is not tight, the outside air is drawn into making the circulation pressure increased to ensure that the mill wok under negative pressure. The increased air flow enter into the dust through the duct, at last enter into the atmosphere after purification.

With the conventional roller mill design, when fine grinding, the classifier tails (rejected particles) are also quite fine and can be easily entrained into the airstream. However, the fine grinding roller mills is designed with a separate path for the coarse reject material to travel back to the grinding zone in such a way that particle short circuiting is avoided.
