A bulk sample (S2) was taken from the feed to a SAG mill at Buzwagi Gold Mine in Tanzania, representing one of the three main ore blends of the mine. The particle size (x F, 80) of the ore blend was 122 mm. The main ore components were identified through washing and manual sorting of the bulk sample.
The General Function of Ball Mills. A ball mill is a grinder used for grinding and blending materials for mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. Appearance. Ball mills have various designs and functions, ranging from laboratory-scale versions to large industrial models.
