main source of heat loss in ball milling

Nov 29, 2014 Friction heat at ball screw/nut. The heat generated at the ball screw/nut connection is due to the rolling friction occurs among them. Unlike the guide ways, the heat generated in the ball screw/nut is distributed on a narrow region which results on a larger temperature rise and larger thermal deformation for the ball screw
