For the current work, extensive surveys have been p erformed on an industrial overflow ball mill, processing iron ore. The slurry density was s et to different values by adapting the water addition flow at the mill inlet. The mill is equipped with a Sensomag which provides information about the ball load and pulp volume, va lues and positions.

22 May, 2019. 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. At a certain height, it will automatically ...

Measuring filling is also necessary to estimate the composition of the load for mill modelling: rock and slurry for AG mills; rock, balls and slurry for SAG mills; or balls and slurry for ball mills. In the case of SAG mills, this requires two separate filling measurements: one for a crashstop and one following a complete grindout to quantify ...

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.
