Main Features of a Modern Wire Rod Mill – IspatGuru
03.01.2014Modern wire rod mills are normally designed to work with 'overall equipment effectiveness' (OEE) philosophy. OEE value of the mill is the value obtained by multiplying mill utilization, mill efficiency, and the mill yield time. The mill utilization is the available operating time divided by the planned production time and expressed in percentage.

Grinding Media Rods
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 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.
