Vertical pulverizer as a blast furnace blowing pulverized coal equipment, the vertical mill greatly alleviates the tight supply and demand of coking coal. The coal to coal ratio of blast furnace injection has been increasing year by year, and has gradually become one of the indispensable furnace charges for iron and steel enterprises.
It can be seen that for coal with high volatile content and flammability, or for pulverizing equipment that grinds pulverized coal particles more uniformly, and some boilers with enhanced combustion, the fineness of pulverized coal can be appropriately larger, saving coal grinding energy consumption.
The coal to coal ratio of blast furnace injection has been increasing year by year, and has gradually become one of the indispensable furnace charges for iron and steel enterprises. Injecting pulverized coal to replace part of coke can save coking investment, reduce coke oven construction and reduce air pollution caused by coking. As for the Vertical Pulverizer for pulverized coal preparation, the mechanical quality and output standards will be higher, and the pulverized coal preparation process will be more rigorous, with quality and quantity guaranteed.
Various coals in the coal resources have different degrees of hardness and softness, and their anti-wear ability is also different, and the economic fineness of each coal is also different. Therefore, a kind of grinding equipment is needed to assist in order to solve the above problems. It is obvious that the above problems do not exist in the vertical mill. Compared with the situation that small and medium-sized customers choose the European version mill for coal powder processing, the stronger customers directly choose the vertical mill.
At present, the large-scale thermal power plants and cement plants at home and abroad basically use the vertical mill. The LUM ultra-fine vertical mill is applicable to the grinding of limestone powder for desulfurization in power plants, the grinding and separation of various non-metallic minerals Large scale projects such as deep processing of fine slag powder and preparation of pulverized coal for blast furnace injection.
We know that the vertical mill is suitable for materials: limestone, lime powder, marble, silica, talc, kaolin, gold, ferrite, clay, slag, marble, etc, These materials are also widely used in the concrete field. With the continuous maturity of the vertical mill technology, the preferred equipment for pulverized coal will be left to the vertical mill.
