A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
Plant start-up was accomplished during the last quarter of 2012. Comminution is accomplished by primary crushing, SAG milling and pebble crushing followed by ball milling. The concentrator is a single line configuration, comprising of one FL 40 ft. diameter × 22 ft. long (EGL) SAG mill driven by a 24,000 kW gearless drive.
CONCLUSIONS This paper outlined a new ball mill scale-up procedure. This procedure relies on data from two laboratory tests, and these laboratory tests need about 20 kg of sample only.
