• Ball Mill for Cement Grinding Process

    Working Principle of Cement Ball Mill: When Ball Mill is running, the raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.); when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, raw material in the cylinder
