# Ball Mill Pdfsag Mill Vs Ball Mill

difference between sag mill vs ball mill - mech4study,ball mill is a fine grinder. a horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. the ball charge of a sag mill is about 29% to 30%. by friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness..what’s the difference of ball mill, sag mill, ag mill?,the ball mill contains materials meant for crushing and grinding, such as balls of ceramic, small rocks, or balls made from stainless steel. the internal device of the ball mill grinds material into powder-like substances, and can rotate continuously for optimal grinding and refinery production..

### Calculate And Select Ball Mill Ball Size For Optimum Grinding

the ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target p90 . based on his work, this formula can be derived for ball diameter sizing and selection: dm <= 6 (log dk) * d^0.5 where d m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.

### Ball Mill - Wikipedia

a ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. it works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. a ball mill consists of a hollow cylindrical shell rotating about its axis. the axis of the shell may be either
