The speed of ball mill directly affects the motion state of steel balls and ores in the ball mill. When the speed is too slow, the steel balls and ore will slide down without rising high, and the crushing effect will be small; when the speed is too fast, the grinding medium will attach to the inner wall of the ball mill and rotate.
