In the blast furnace slag, steel slag resource utilization and environmental protection project site of orson steel plant in Hebei,the reporter know all the project's "leading role", from Great Wall Machinery slag vertical mill.
Slag vertical mill "nature of work" is similar to a coffee machine, after steelmaking slag into the output, after drying, fine grinding, screening, into slag powder. This slag vertical mill is four or five stories high, 4.6 meters in diameter disc with four grinding rollers to meet the annual output of 600,000 tons of slag production line requirements. Project from last year to start construction in June 2014, only less than seven months to complete the design, manufacture, installation, commissioning and formally put into operation.
In the interview, Aosen steel plant official told reporters, hosts slag vertical mill and ball mill grinding slag compared to traditional, can effectively reduce energy consumption in the production process 20-50%, while grinding out slag powder specific surface area of control in 4200 ~ 5000 cm² / g when the system power consumption does not exceed 40KWh / t, while saving energy and reasonable control of slag cement fineness and suitable slag cement and graded to achieve portland cement and slag the best match for the steel letter cement production quality and efficient cement products.
