How Does The Ultrafine Vertical Roller Mill Produced By Grinding Mill Manufacturer Clirik Work?
2018-07-12
The ultrafine vertical roller mill is the newest grinding mill of Shanghai Clirik, a professional grinding mill manufacturer in China. The ultrafine vertical roller mill integrates the functions of grinding ,classifying,conveying, secondary classifying, and packing progress into one machine.Its powder fineness can reach 400-3000 mesh.
The vertical mill mainly consists of the reduction gear,grinding plate,classifier,grinding rollers, mill body,oil station,pressure-applying device, motor, and electrical system.
Work principle of vertical mill:
The grinding plate is rotated by the main motor via the reduction gear.Meanwhile,high pressure air enters the mill interior via the air inlet. Materials then fall onto the center of the grinding plate in rotation by the screw conveyor feeder. Due to the centrifugal force,the materials evenly move from the center of the grinding plate towards its fringe.while passing across the track in the grinding plate,large blocks of materials are crushed and grinded directly by the grinding roller. The fine particles form the material bed,owing to squeezing ,where the inter-particle crushing take3s place until grind to the fine powder.
The fine powder continue to move towards to fringe of the grinding plate until they are taken away by strong air flow at the air ring.While the materials alone with the air flow pass through the separator located above the grinding plate, the coarse particles return to the grinding plate for re-pulverization due to the action of the rotor blase, the fine particles along with the air flow leave the mill interior and are collected and discharged as finished powder product by the powder collector.
