How Ball Mill Ore Feed Size Affects Tonnage Capacity

The important of crushing your ore and rock fine and properly is often forgotten. The finer you crush, the higher your ball mill tonnage and capacity will be. The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of ...

where d b.max is the maximum size of the feed (mm), σ is the compression strength (MPa), E is the modulus of elasticity (MPa), ρ b is the density of material of balls (kg/m 3), and D is the inner diameter of the mill body (m). Generally, a maximum allowed ball size is situated in the range from D/18 to D/24. The degree of filling the mill with balls also influences the productivity of the ...

feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20-75 mm. The biggest size is chosen when the mill is used as a primary grinding mill. For fine grinding of e.g. sands, balls can be replaced by cylpebs, which are heat treated steel cylinders with a diameter of 12-40 mm and with the same length as the diameter ...

Effect of ball and feed particle size distribution on the ...

01/06/2018  For the feed sample sizes investigated, the three ball mix was more effective for the coarser feed due to the presence of the 50 mm balls whilst with a finer feed the binary mix gave the optimal amount of size class of interest. These results prove that a close control of feed and ball match is of paramount importance if one is to improve the efficiency of milling circuits.
