SMMVIK steel mill medium speed coal mill
In recent years, most of the coal used in steel mills is anthracite, bituminous coal, etc, the coal quality is good, and the coal gangue is less, so the amount of slag discharged during the operation of the medium-speed coal mill is relatively small. In recent years, with the increasing shortage of high-quality coking coal resources in domestic, the price of coke has continued to rise, and the economic effect of coke and blast furnace injection coal substitution has become more and more obvious. The status of blast furnace injection coal technology in the steel smelting process is increasing. It plays an increasingly important role in saving smelting costs in the iron and steel industry. SMMVIK develops better pulverizers to help steel mills grind coal.
Introduction to the principle of the production line of medium speed pulverizer in steel mills
The pulverizing system of the steel mill is a negative pressure system, and the drying gas is circulated or non-circulated by the powder exhaust fan. The mixed gas enters the medium-speed coal mill to dry the pulverized coal to form a wind-coal mixture. The pulverized coal is filtered out by a bag filter, and the remaining gas is discharged into the atmosphere through a powder exhaust fan. The end of the pulverized coal path is the iron-making blast furnace, which mainly provides C element for the blast furnace for iron-making. The blast-furnace gas produced by the blast-furnace iron-making can be directly burned through the heating furnace to provide high-temperature gas for drying the pulverized coal.
Characteristics of SMMVIK Medium Speed Coal Mill
Smmvik medium speed coal mill is customized for different industries, such as pulverized coal preparation, pulverized coal station, pulverized coal boiler, pulverized coal workshop, rotary kiln and lime kiln. Smmvik medium speed coal mill is simple in system, convenient in operation and adjustment, and high in automation. It is not only suitable for large-scale and super large-scale industrial production, but also suitable for medium and small-scale production. The product fineness ratio is high, the manufacturing accuracy of the powder concentrator is high, and the powder separation efficiency is high. It is more suitable for the production of ultra-fine powder.
At the same time, the SMMVIK medium-speed coal mill is equipped with a built-in 5-level safety explosion-proof system to ensure safe production, and the entire production process complies with strict environmental standards. While stably producing powder, there is no other worries. For model price, please call customer service.
