| Working principle | - 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.
|
- 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.
|
- 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.
|
- 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.
|
- 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
|
| Advantages | - Stable rotation, reliable operation: Raymond mill host transmission device adopts sealed gear box and belt wheel, smooth transmission, reliable operation.
|
- High sieving rate: Compared with other milling equipment, it has a high through-screening rate, which is up to 99%, and is generally unattainable by other milling equipment.
|
- Long service life of wearing parts: The materials of wearing parts are high manganese steel, long service life, and the motors are national standard products.
