Energy-saving technical transformation practice of ball mill in a copper slag ore-dressing plant
Translated Abstract
A copper slag Ore-dressing Plant adopts the grinding process flow of semi-automatic grinding ball milling,and the ball mill adopts CITIC Heavy Industries φ5.03*7.5 m overflow ball mill,the pow-er consumption of ball mill in daily production accounts for more than 40％of the total power consumption of the whole plant.Through a series of technical transformation:optimization and transformation of mill liner,replacement and transformation of mill motor,optimization and replacement of grinding medium,and technical renovation of one stage overflow rapid flotation,the power consumption per ton of ball mill has been effectively reduced,the power consumption per ton of mill has been reduced from 27.27 kW·h to 20.71 kW·h,and the power consumption per ton of mill has been reduced by 6.56 kW·h.According to the calculation of 750 000 tons of slag treatment per year and 0.55 yuan/kW·h of electricity cost,4.92 million kW·h of electricity can be saved per year,and the electricity cost is about 2.706 million yuan,obtaining good economic benefits.
