CHAENG can undertake EPC turnkey services for slag(Slag product applications) / steel slag / nickel slag / manganese slag powder production line with an annual output of 200,000-1,500,000 tons.
So far, CHAENG has established successfully more than 100 slag production lines in the world.
Over the past decade, it shows that the general trend of cement industry in Germany and Switzerland, which are strong power in world cement industry, is that the traditional portland cement is replaced by the type II cement which is added into large amounts of slag, fly ash, sintered shale, volcanic ash, limestone and relatively less clinker.
GGBFS is a kind of concrete admixture with superior performance. Adding GGBFS during cement production can increase the strength 28D of cement by 15% - 20%, to admix 42.5 grade cement, and during concrete production, slag powder can replace 10 ~ 50% of the cement, to mix C20 ~ C60 concrete, which has become an important measure to reduce the cost of cement in the international cement industry.
Piles of slag are taken and fed by the forklift truck, and conveyed by a belt conveyor. During the process of conveying, slag raw material will be iron-removing and screening through magnetic separator and vibrating screen, and then go to the weigher cabin, elevator and last to the vertical roller mill for grinding process. The ground granulated slag powder is drying by the hot air supplied by hot blast furnace, and with the help of hot air, the powder selecting is made in the separator. The qualified slag powder particles will be collected by bag dust collector, then conveyed to and stored in the silos by the air slide and elevator.
Suggestions for the equipment selection
CHAENG already has more than 100 customers currently, and almost 80% of them built slag grinding plant with annual capacity of 1,000,000 tons, 600,000 tons, 300,000 tons. Below table has shown the three main equipment in aspects of model selection, energy consumption and so on.
