The hardness of the high alumina ceramic ball is 9, and the density is g/cm³, in the wet milling process, when the filling amount of the balls reaches 55% of the net volume of the ball mill, the best state can be achieved. The weight of the balls in the ball mill can be estimated with an empirical formula.
