May 22, 2019 0183 32 The ball mill consists of a metal cylinder and a ball The working principle is that when the cylinder is rotated, the grinding body ball and the object to be polished material installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force...
The total feed to the ball-mill was therefore 1154 T per hr or 179 per cent, of the original feed It was evident that the ball-mill was greatly underloaded in this test, but so much trouble developed in the classifier, due to the tendency of the sands to slip down the slopes, that a more rapid feed was not attempted at this time...
the mill is used primarily to lift the load medium and charge Additional power is required to keep the mill rotating 813 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 83 Ad this can be used to establish the essential features of a model for mill power...
