With the rapid development of industrial equipment, the grinding machine vertical mill has entered a mature stage. But at the same time, entering the maturity stage also marks the entry into the bottleneck period and requires new breakthroughs.

CHAENG vertical mill is quite mature in dealing with slag, and has more than 100 cases at home and abroad, and has been widely praised by customers. Industrial wastes have also been treated with nickel slag and steel slag, but the technology is relatively not very mature, especially in steel slag.

Steel slag is a by-product produced in the steelmaking process of steel plants, and contains many components. There are two main ways for steel slag to be used as a secondary resource. One is to be recycled as a smelting solvent in the factory. It can not only replace limestone, but also recover a large amount of metal iron and other useful elements. The other is as a road building material. Raw materials for building materials or agricultural fertilizers.

In addition, steel slag can also be ground by slag vertical mill to produce steel slag powder for use in new building materials.

The new concrete, through the grinding process, enhances the activity of the industrial waste and enters the concrete as a concrete admixture. Fine grinding not only reduces the slag powder particles, increases its specific surface area, further hydrates the f-CaO in the slag powder to improve the stability of the slag powder, but also changes the lattice structure and surface physicochemical properties of the steel slag. The grinding energy is converted into the internal energy and surface energy of the slag powder to improve the gelation property of the steel slag. The high-performance concrete cementitious material can be prepared by using the stimuli of the steel slag micropowder and the blast furnace ore powder and the appropriate activator.
