Diffusion-type pulverized coal combustion process for comprehensive utilization of blast furnace slag in iron and steel industry
The blast furnace slag in iron and steel industry can become GGBS after drying and grinding, which is recyclable in cement industry. Mixed with cement clinker powder in a certain proportion, it can reduce the cement production cost. Our company provides high efficiency and energy saving environmental protection diffusion-type pulverized coal combustion technology (state invention patent). By grinding the coal while drying it, it can realize the waste recycling. The ratio of GGBS and cement clinker can be up to 3:7.On one hand, it can solve the waste residue treatment problem;on the other hand, it greatly reduce the production cost of cement industry. We have established about ten process lines, which has been widely used in cement building materials industry and commercial concrete industry.
