The main part of the ball mill mainly include feeding part, discharging part, a rotary part, a transmission part (reducer, small gear, motors, electrical control) and other parts. Hollow shaft adopts steel castings, the liner is detachable, slewing gear hobbing with casting, the cylinder body with wear-resistant liner, with good resistance to wear.احصل على السعر
09/03/2016 I have an issue to select a proper motor. I see some challenges here : 1-The jar will contain metal balls which will be a heavy load to rotate. (I think 1/3 HP at least would be needed) 2-The jar rotation should be constant (80 RPM). 3-It will run for long time <--- at least for 11 continuous days.
