One、Process flow of Guilin Hongcheng Mine powder vertical mill production line:
The raw slag into the feeder into the feeder, after measuring by the conveyor belt into the spiral feeding device feeding HLM roller vertical grinding, material in the mill rotation with the mill moved from the center to the edge under the action of centrifugal force, after compaction, degassing, grinding process, the material from the hot air from the mill ring, and instant drying, the fine particles were taken to the mill for sorting, and the coarse powder is returned to the mill and grinding. Qualified fine powder is brought into the bag dust collector to separate the air powder after the finished product collection. The finished product is collected and transported into the finished product bulk warehouse, and the waste gas is discharged after sound elimination by the fan. Some of the difficult to wear large particles (and iron tumor and iron slag) enter the external circulation system through the slag discharge mouth at the air ring, and are fed to the mill again after removing the iron. The hot air required for the mill drying and ventilation is provided by the hot air furnace, and the insufficient part is replenished from the atmosphere by the cold air valve. The system has high air capacity and strong drying capacity, and the moisture content into the grinding material can reach 8-15%.
two 、Design process advantages of ore powder vertical mill production line:
1.Save land The whole production line is tight in structure and occupies a small site. A mineral powder production line with an annual output of 300,000 tons only needs 20-25 mu of land, 40 0,000 tons covers an area of 25-30 mu, and 600,000 tons only needs 30-35 mu of land.
2.low noise, environmental protection standards The noise and vibration of the production line during the operation are very low, coupled with the dual treatment of the sound insulation room and the muffler of the fan device, making the noise emission of the system less than 60-70 decibels, which can fully reach the standard.
3.greatly save power Due to the advanced grinding mechanism, simple process and small installed capacity, the grinding ultrafine powder can save 45-60% of the electricity than the traditional pipe grinding system, and the grinding cement can save 35-40% of the electricity.
4.dust emission standards The whole production line adopts negative pressure operation, and uses the mature technology and reliable gas box pulse bag dust collector to collect the finished products. The dust emission in the production process is controlled at 30-50mg / m ', which can fully meet the standard.
