Product Application

CLUM series Ultrafine Vertical Powder Grinding Mill is suitable for huge capacity producing, widely used in grinding non-flammable and non-explosive materials under 7(the Moh’s hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.

Working Principle 

CLUM series Ultrafine Vertical Powder Grinding Mill mainly consists of the motor,reduction gear,grinding rollers,grinding plate,pressure-applying device,classifier,mill body.oil station ,and electrical system.

CLUM series Ultrafine Vertical Powder Grinding Mill grinding plate is rotated by the main motor via the reduction gear. Meanwhile ,high pressure air enters the mill interior via 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 takes place until grind to the fine powder.

CLUM series Ultrafine Vertical Powder Grinding Mill fine powder continue to move towards the fringe of the grinding plate until they are taken away by strong air flow at the air ring.While the materials along 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 blade,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.

Product Advantage

1. Good quality of finished products: Finished products have high whiteness, fine particle size, narrow particle size distribution, and good particle sphericity. The fineness D97 of the finished powder can reach 3000 meshes, and the content of 2μm can reach up to 60%. 

2. High grinding efficiency: save 20~30% power consumption compared with the ball mill. 

3. Strong drying capacity: dry and grind raw materials with moisture content as much as 15%. 

4. Multifunction: crushing, drying, grinding, separating, and conveying. 

5. Low noises and little dust: no direct contact between the grinding rollers and grinding disc, so metallic impact is avoided, and its noises are 20~25 decibels lower. Totally closed negative pressure operation has been employed by this vertical grinding mill, so there is little dust during the operation. 

6. Low wear rate and little metallic pollution: its metal wear is only 5~10g/t. Low wear rate and little metallic pollution: its metal wear is only 5~10g/t.
