However, since the early phases the project team specified a grinding circuit with a state-of-the-art technology for the mills. SPCC has chosen the variable speed gearless mill drives (GMD) technology for their Ball Mills, which brings multiple advantages in terms of efficiency and availability in comparison to standard ring-geared mills.
Mount Polley is an open-pit copper and gold mine in British Columbia, wholly owned by Imperial Metals Corporation (Imperial), which produces on average 20,000 tons per day. The existing mill capacity is 20,000 tons per day with a reported availability of 92 percent, which Imperial intends to expand to a rate of 30,000 tons per day.
High malleability reduces grinding rates and high density creates buildup in the ball mill-cyclone circulating load. At the Golden Giant Mine it was found that gold ground up to twenty times slower than associated gangue and that cyclone partition curves typically showed over 95% of gold reports to the underflow ( Laplante et al., 1990, Banisi ...
The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P 80 less than 100 μm.
A comprehensive energy study was carried out for the Red Chris mill, which processes copper-gold ore at a rate of 30,000 tonnes per day (t/d) and is located in Northern British Columbia. The study focused on identifying opportunities for energy conservation in the semi-autogenous grinding (SAG)-ball mill and regrind circuits.
A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.
