A laboratoryscale tumbling rod mill was designed for this study, and six operative parameters were tested and analyzed in order to detect the main influences on the mill product, attending to material requirements for further processes such as recirculation load or froth flotation for beneficiation.
WhatsApp: +86 18838072829Good figures for rod and bar mills are 90 % to 93 %, for structural mills, the good mill utilization figures are 75 % to 78 %. If a mill rolls 80 % of the calendar year, that is 365 x 24 x = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of tons/hour.
