The iron and steel smelter will produce 5 million tons of blast furnace slag every year. Commonly, there are steelmaking pig iron slag, foundry iron slag, and manganese iron slag. The slag displacement is negatively correlated with the ore grade, the ore grade is low, and the amount of slag produced is greater. A large number of blast furnace slags in the city occupy a large amount of construction land, and at the same time cause dust and solid waste pollution. Chaeng GRMS vertical grinding breaks through the technical problems of slag powder processing, deep processing existing slag for new building materials manufacturing, and opening a new economic era of slag powder.

The application of Chaeng GRMS vertical grinding slag powder has been officially put into operation. Shanxi users said that “slag powder can effectively improve the application performance of concrete and reduce the cost of concrete production”. Vertical roller mill adopts the principle of vertical abrasive layer grinding. The material has a short residence time in the mill and reduces repeated grinding. Therefore, the product contains less iron and has high whiteness and purity. After the fineness of the slag powder reaches the second standard, it can replace the natural sandstone and re-appear its hidden value in the construction of highways, airports, foundation works, railway slag, concrete aggregates and asphalt pavement.

I have the forefront of various mineral resources reserves. While accelerating the pace of economic development, we must also focus on developing energy deep processing industries and tapping the relatively large value of existing resources. The slag belongs to the waste in iron and steel smelting, and plays a new role after the secondary grinding of the slag by the ultrafine grinding of the vertical mill. The slag powder can be used to prepare slag crushed concrete, applied in soft foundation, asphalt pavement paved with slag gravel as base material, and used for railway track slag to properly absorb the vibration and noise generated when the train walks, and its anti-skid and wear resistance. Much better than the two materials.

The downstream products of blast furnace slag mainly include water slag, slag gravel, expanded slag and slag beads. In order to meet the standards of slag powder in different industries, Chaeng GRMS vertical mill adopts the principle of multi-head separator, each rotor can be frequency-controlled In order to achieve automatic adjustment of discharge fineness and broaden the application field of slag powder.
