Raymond winnowing process

After grinding material, fans will be blown inside the White chassis, blowing powder by grinding chamber placed above the analyzer sorting, fine through coarse material falling into the grinding chamber for regrinding and fineness meet the specifications into the cyclone collector with the airflow through the collected powder discharge port, is finished. Winnowing pulverizer Mill the cyclone collector return air back into the upper end of the fan duct, the air duct is circular, and the flow under negative pressure, air flow circulation path is increased by the fan and the host portion of the intermediate exhaust pipe is discharged into the small cyclone collection , a purification.
High pressure mill works:
High pressure mill host, the high-pressure grinding roll hanger fastening 1000-1500 kg pressure spring. After beginning work, grinding spindle rotary roll around and under the influence of high pressure spring and centrifugal force, close to the ring rolling mill, rolling pressure ratio Raymond powder machine under the same dynamic conditions 1.2 times higher, the yield is much improved. When the material is ground into the grinding chamber, fed by the shovel blade between RCC roller and grinding ring, powder rolling over after the circulating air blower into the analysis machine, qualified with the gas inflow whirlwind of powder powder feeder is finished, the large particles tablets to regrinding. Circulating air blower to repeat the above process, I entered the Wind bag filter purification. When the grinding roller and grinding ring reach a certain wear and tear, high-pressure adjustment spring length, maintaining a constant pressure between grinding roller and grinding ring. Thus ensuring a stable yield and fineness.
High Pressure Mill Features:
A high pressure grinder mill, compared with other under the same dynamic conditions such as 10-20% increase in production,Raymond Mill the pressure roller grinding improved 800-1200kg of materials under high pressure spring.
2 Mohs hardness of less than 9.3 of mineral materials can be processed crushed.
3 finished a wide size range, the most coarse particle size of up to 0.613 mm (30 mesh) particle size generally up to 0.033 mm (425 mesh), the few materials can reach 0.013 mm (1000 mesh).
