Rotational Speed of Ball Milling Method

Steel balls moving the state in ball mills is related to its size, material composition, and rotational speed. If we want to analyze the moving state of steel balls in the ball mill, first, we should consider its stress: steel ball’s gravity itself, centrifugal force when doing circular motion, and friction force from the relative motion with the cylinder.
