Ball mill design consists of feeding part, discharging part, rotary part, transmission part (reducer, small gear, motors, electrical control) and other major parts. Hollow shaft is steel castings, and the liner is detachable. Rotary gear is processed by casting hobbling. The cylinder is lined wearresistant liner plate with good resistance to wear.
