working principle
This cement mill is widely used in the grinding of cement raw meal, slag(GGBS plant), cement clinker, raw coal and other raw materials. It gathers grinding, drying and powder selecting as a whole, with high grinding efficiency and high drying capacity ( the maximum handling material moisture is up to 20% ). The vertical mill adopts dynamic powder selecting device, which comes with high powder-selecting efficiency and convenient adjustment of fineness.After crushed by crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.The grinding disc is driving by motor through reducer.
The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high effiency classsifer.
The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.
