The steel slag vertical mill can integrate fine crushing, grinding, drying, powder selection, and conveying. It can grind various industrial waste slags, help steel plants to realize effective utilization of slag resources, and improve overall environmental and economic benefits. When dealing with steel slag, due to various factors such as poor grindability and poor stability of the steel slag itself, it is necessary to improve the vertical mill to adapt to various problems when grinding steel slag.
Add iron selection at many places such as steel slag entering and exiting the mill, and screening the excess metal iron in the steel slag. Before entering the mill, the metal iron content of the steel slag tailings after purification and iron removal is less than 2%, and the fineness is less than 10mm. The specific surface area of the steel slag powder produced after grinding by the GRMSS steel slag vertical mill is 400-500㎡/kg, which fully achieves the expected effect, is environmentally friendly and efficient, and realizes the high-value resource utilization of steel slag.
During the operation of the vertical mill, the grinding roller and the grinding disc are mutually crushed. In order to ensure the service life of the vertical mill, it is necessary to add a wear-resistant layer on the grinding roller and the grinding disc. However, because of the poor grindability of steel slag, it is necessary to thicken the wear-resistant layer on the grinding roller and grinding disc of the vertical mill for multiple wear resistance. The multi-layer surfacing of the wear-resistant layer by Xinxiang Great Wall shows our advanced technology to ensure the service life of the vertical mill.
