Jan 03, 2020 A new method was adopted to measure the total retention time taken by each ore in the BBM. The retention time of the ore in the mill is measured based on the total number of revolutions taken by each ore to produce 250% of circulating load. The number of revolutions for each trail is set to the BBM based on Bond’s procedure.

Excluding stockpiles and surge bins you and not considering a complicated flotation circuit (i.e rougher scavenger and not rough- cleaner - recleaner with a regrind circuit - scavenger) you are probably looking at 30 to 60 minutes for SAG mill, 45 to 60 minutes for ball mill, and then one to 3 hours for flotation, and one to 3 hours for thickening/filtering, for a total of 3 to 6 hours which could get to 8 hours.
How To Find Ball Mill Retention Time In Case Of Iron Ore Pdf The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals.

Oct 25, 2017 The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
Jul 15, 2013 For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.
Milling was carried out in a laboratory ball mill 312 284 mm (diameter length). The ball distribution was fixed at equal volume fraction of 15 and 23 mm balls. The mill speed was set on N c =71%. The concentrate was charged to the mill and rotated for a specific time, and then discharged. Five samples with different Blaine specific
