The final fineness of the materials after grinding at the vertical roller grinding mill can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≤5um.
Under the same finished final size and the same motor power, the capacity of the vertical roller grinding mill is twice as much as jet mill, mixing grinder and ball mill.
Vertical roller grinding mill would be the crucial equipment to smash right after material to be broken. Vertical roller grinding mill is extensively utilized in cement mill, fly ash mill, silicate solutions, new creating supplies, refractory components, fertilizer, ferrous and nonferrous metal and glass ceramics as well as other mineral production industries.
Grinded by vertical roller grinding mill, fly ash can be used as raw materials for Portland cement. Use of fly ash as a partial replacement for Portland cement is generally limited to Class C fly ashes. Class "F" fly ashes can have volatile effects on the entrained air content of concrete, causing reduced resistance to freeze/thaw damage. Fly Ash often replaces up to 30% by mass of Portland cement, but can be used in higher dosages in certain applications. Fly ash can add to the concrete’s final strength and increase its chemical resistance and durability. Fly ash can also significantly improve the workability of concrete. Recently concrete mix design for partial cement replacement with High Volume Fly Ash (50% cement replacement) has been developed.
