the ball mills are operated at a ball charge volume of 3032% and 78.5% critical speed. the sag mill trommel undersize is combined with the ball mills discharge and pumped to two parallel packs of twelve 660 mm diameter cyclones. the cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed
mill critical speed determination. the critical speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shells inside surface. this is the rotational speed where balls will not fall away from the mills shell. result this mill would need to spin at rpm to be at 100%
sag milling extends itself to many applications due to the range of mill sizes available. they can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. sag mills are also an optimum solution for wet grinding since crushing and screening in these
difference between sag mill vs ball mill mecstudy. ball mill is a fine grinder. 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
sag mill, hpgr and ball mill in an abc closed circuit. instead of recycling the larger size fraction, the oversize product from agsag mills is sometimes prevented from discharging from the mill by using a reverse spiral at the discharge end and washes back into the mill for further grinding
