As the important equivalent substitutes for cement production,GGBFS can not only significantly improve the overall performance of cement and concrete, but also significantly reduce the production cost. Now it has been widely used in cement plant, grinding station and steel factories as a new kind of high effectively admixtures. For this situation, we may say: "who first invests will first benefits."

CHAENG (Great Wall Machinery) can undertake 20 tons --1.5 million tons of Blast furnace slag/Steel slag/Nickel slag/Manganese slag powder production EPC projects. Up to now, CHAENG has constructed more than 100 slag grinding production lines at home and abroad.

Process Description

The stacked slag is packed and feed by the forklift trucks, then transported by belt conveyor. During transmission, the slag will pass through the iron separator and vibrating screen, then through the weighing equipment and elevator, finally come into the vertical roller mill. With the hot air form cowper stove, the slag after grinding, will come through the separator, while drying. Slag meets the fineness requirement will pass through the separator, then delivered by air blower and elevator, finally come to the storage silo.

Why choose vertical mill for slag grinding ?

Energy-saving, environment friendly, simple process, high intelligence

Nowadays, the slag vertical roller mills are widely accepted by customers, but some customers may still doubt about the vertical roller mill and ball mill. By doing research in more than 10 customers factory, we have summed up these difference between this two kinds of mills.
