Bisha Efficient Process Plant Ball Mill Sag Mill

what's the difference between sag mill and ball mill,the ball mill adopts a discharge screen similar to the ball mill, and the function of blocking the internal medium of the overflow ball mill is accomplished inside the rotary part of the ball mill. the discharge screen is only responsible for forcing out a small amount of the medium that overflows into the discharge screen through the internal welding reverse spiral, to achieve forced discharge mill..method of assessing ball mill health,ball mill power draw 14 354 kw (corrected to pinion output/mill shell); hydrocyclone overflow p80 90.5 µm; hydrocyclone underflow (ball mill feed) 15.8% passing 90.5 µm; ball mill product 40.3% passing 90.5 µm; and sag mill screen undersize 41.0% passing 90.5 µm. laboratory test result, survey ore sample.principles of sag and ball mill operations,sag milling in australia – focus on the future248 Кб. developments in sag mill design and operation over the last few years, sag mill manufacturing technology has advanced rapidly.retro-fits have been favoured as operators moved to more competent ores, with open circuiting of the sag mill and ball mill additions topping the list..
