Aug 26, 2017 Norman and Hall report that high carbon martensitic steels are best suited for wear resistance. Depending on the hardenability and impact levels required, carbon content of steel for grinding balls vary from 0.5 to 1.1% whereas, for grinding rods lower carbon content of 0.6 to 0.8% is used because of more severe heat treatment cooling rate.
The grinding rod steel is type 1,0% C 1,4% Cr. The dimensions range is from 75 mm to 120 mm. The hardness range is 340 400 HBW. Rod mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill.
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
