### grinding dry ball mill - grinding & classification

grinding dry ball mill (1 reply) We production dry Iron Cocentrate with grade 65.5% without water. One of our problems is to grinding iron ore up to 75 microns.After charging balls in the mill, larger (50&40mm) balls at the end of the mill and smaller balls (25&30mm) mills are located at the beginning of the mill,which reduces the effective grinding.Is it possible to dry the ball mill with a 75 micron product?
