High Capacity 23-220 t / h Slag Ultrafine Powder Vertical Grinding Mill
Description
When the slag melted in blast furnace ironmaking is rapidly cooled, the glassy substance formed before it has time to crystallize is slag. The slag is an active mixed material for cement after being ground.
Hefei Hengcheng slag vertical mill can integrate fine crushing, grinding, drying, powder selection and transportation. Its overall structure is reasonable, professional technology, simple control, easy operation, stable and reliable operation, and convenient maintenance. The main technical and economic indicators reach professional standards. Level.
【Working Principle】
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when it passes through the annular groove on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

【Product Advantages】
Low Investment Cost
HVM slag vertical mill has the advantages of crushing, drying, grinding, powder separation and conveying. The comprehensive investment cost is low, the floor area is small, which is 50% of the ball mill, and it can be arranged in the open air, which saves the construction cost.
Intelligent Control
The HVM slag vertical mill production line is equipped with a PLC automatic control system, which can efficiently realize remote control, easy to operate, and has a high degree of intelligence, which greatly reduces labor costs.
Strong Drying Ability
The mill can be directly ventilated with hot air, and the moisture content of the material is as high as 15%. There is no need to configure a dryer, which saves investment costs and energy consumption costs, and can meet the production needs of drying and grinding materials with different humidity.
Reliable Operation
The HVM slag vertical mill production line adopts the grinding roller limiting device, which can avoid the vibration caused by the material cut off, and the new grinding roller sealing device has more reliable sealing, no need to seal the fan, and better explosion suppression performance.
Energy Saving
In line with the national environmental protection and energy saving requirements, the system is integrally sealed, fully negative pressure operation, no dust spillage, clean operating environment and reduced consumption, which is conducive to enhancing the market competitiveness of enterprises.
