“A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 Ib (227 kg). Tumbling around in the mills with the hard taconite wears away the rods and balls and need to be replaced frequently.” This is a costly and energy-intensive process and the waste rods and balls are a disposal problem, according to NRRI.

Effects of percent solids and mill loading on ball wear in ...

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp ...
