Medium Speed Coal Mill In Steel Plant

Last Update:2020-05-14 10:06:16

In recent years, most of the coal used in the steel plant is anthracite, bituminous coal, etc., with good coal quality and less gangue, so the amount of slag discharged during the operation of the medium speed pulverizer is relatively small. In recent years, with the increasing scarcity of high-quality coking coal resources in China, the price of coke continues to rise, and the economic effect of the substitution of coke and blast furnace coal injection becomes more and more obvious. Blast furnace coal injection technology plays an increasingly important role in the iron and steel smelting process, saving the cost of smelting in the iron and steel industry. Liming heavy industry develops better pulverizers To assist coal mill in steel plant.

The pulverizing system of steel plant belongs to the negative pressure system, and the dry gas is recycled or non recycled through the powder exhaust fan. The mixed gas enters into the medium speed pulverizer to dry the coal powder, forming the air coal mixture, filtering the coal powder through the bag filter, and the remaining gas is discharged into the atmosphere through the powder exhaust fan. The coal powder path terminal is the blast furnace, which mainly provides C element for the blast furnace for ironmaking. The blast furnace gas produced by blast furnace ironmaking can be directly burned in the heating furnace to provide high temperature gas for drying coal powder.

Liming medium speed pulverizer is customized for different industries, including pulverized coal preparation, pulverized coal station, pulverized coal boiler, pulverized coal workshop, pre kiln pulverization of rotary kiln lime kiln, etc. Liming heavy industry medium speed coal pulverizer system is simple, easy to operate and adjust, high degree of automation. It is suitable for large-scale and super large-scale industrial production as well as small and medium-sized production, with high proportion of product fineness, high manufacturing accuracy and high efficiency of powder concentrator, and more suitable for the production of ultra-fine powder.
