Media shape and mill power The objective of this dissertation was to investigate how media shape affects grinding Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes Load behaviour mill power and breakage as affected by media shapes were studied in a pilot laboratory mill An inductive proximity probe.
Maximize this rate The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the materials grindability as measured in the lab Mill percent solids optimization has thusly been achieved McIvor et al 2000 For media sizing maximizing the mill grinding rate on a given ore is equivalent.
Where y is cumulative percent passing size d d 50 is the 50 passing size n is distribution constant and k is a correction factor The n values ranged from 0 84 to 1 84 and k values from 0 95 to 1 00 By using the Bond method of grindability H Ipek et al 4 have observed that less specific energy input is required in separate grinding of ceramic raw materials than grinding them in.
Effect of slurry rheology and flow rate on mill behaviour He had already highlighted the interaction between slurry and media in the mill by looking at the mill grinding efficiency At that time it was difficult to acquire a lot of valuable information as robustness in an aggressive environment was not assured.
The effects of ball milling conditions on breakage response of Baban Tsauni Nigeria lead gold ore was examined in this research work The three factors considered were the grinding media mass to ore sample mass ratio the grinding time and the ball mill speed The breakage response measured in terms of cumulative per cent mass passing the liberation size increased with increase in media.
