Scale-up method of planetary ball mill - ScienceDirect

A total scale-up method for planetary mill is discussed in this section. All parameters ( d M, h and R) of the basic planetary mill were scaled-up as t p times to investigate the effect of the scale-up ratio on E i. The scale-up ratio was changed from 0.50 to 3.00 ( V M = 170 – 36 650 cm 3; n B = 80 –17 496).

Fluid mechanics of slurry flow through the grinding media ...

The result is a prediction of the slurry profile in both the radial and axial directions. Hence, it leads to the detailed description of slurry mass and ball charge within the mill. The model predictions are verified with pilot-scale experimental work. This novel approach based on the physics of fluid flow is devoid of any empiricism.

Comparison of the Primary Grinding of Taconite in a Pilot ...

The purpose of this study was to compare the performance of a mill charged with rods with the performance of the same mill charged with balls at the pilot scale. The first objective was to establish whether we could achieve the same throughput rate at the same mesh-of-grind in a mill in which the rod media has been replaced by balls.

Effect of ball mill size on media wear | SpringerLink

Correlation of scale-up from small-scale batch laboratory mills to large-diameter industrial mills was established by performing two series of laboratory and pilot plant grinding tests using a magnetic taconite ore and a siliceous sulfide ore. In one series, controlled batch grinding tests in 203-, 508-, and 914-mm (8-, 20-, and 36-in.) diameter mills were carried out followed by a …

Small-Scale Tests to Characterise Ore Grindibility

The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stage-crushed to ½" (12.5mm) and the test is run under a circulating load. The test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14-mesh (1.18mm) sieve is typically used. The rod mill work index is
