These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge.. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.
Grindability - an overview | ScienceDirect Topics
As the HGI ball mill works on the same principle as pulverizing mills, the index obtained from this could give a fair assessment of the grinding capability of torrefied biomass. For biomass, one should use ( Agus and Water, 1971 ; Joshi, 1978) a standard volume of sample instead of mass to compare the grinding ease to coal and torrefied biomass.

This characteristic of ball media wear rate vs the bond index was investigate at part of the AMIRA P9L project 1996-1999. It was found the systems dominated by corrosive wear mechanisms (ie: mild steel media) had wear rate in the 100-159g/kwh range and the systems that did not have corrosive wear mechanisms (Cr media or non-corrosive ores) and were dominated by abrasive and impact wear ...

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

geneous ores. Rod mill work index values often differ from ball mill work index values in the same type ore (40). In homogeneous ores the work index values tend to remain the same for different product sizes. As a supplement to this study, rod and ball mill grindability tests were run on the porphyry copper ore at sizes of 4 through 65 mesh

Rod Mill - an overview | ScienceDirect Topics
Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
