Vertical Mill require a higher stability of material. It has equiped different production line for coal,cement and fly ash. Meanwhile, it can process a volume at one time and its' capacity is 80 - 300tons per hour nomarly. The fly ash which vertical mill produce can be widely used for cement concrete as the filler between roadbed and roadbed layers. The roadbed fly ash will be further processed into high fineness powders. And then this processed fly ash are applied in the cement concrete to replace the same amont conccrete. Thus, we can save a large of cements ultimately!
