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 ...

Existing approaches to ball mill control Several approaches to ball mill control are known. A typical problem is that direct control by feedback from a size analysis of the ground product, for example, is not satisfactory because of the transport time ( often 20 25 minutes between feed and discharge ) of the material being ground and because of the lack of a continuously acting device for ...

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.

Experience has shown that the best grinding conditions for ores in ball mills are created by a slurry density of between 70% and 80% solids by mass [15,16]. This implies that the milling rates are highest within this range. We investigated the effects of slurry density, grinding time and grinding energy on the grindability of a typical platinum ...
