Based on batch grinding method and normalization idea, a conical ball mill is used and a quantitative separation method of grinding characteristics of multicomponent complex ore is proposed. The results show that the feed sizes of polymetallic complex ore have an obvious influence on the particle size distribution of intermediate grinding products in the early stage of grinding.

Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energyintensive process [1,2,3,4]. In this process, the size of the particle obtained depends on the energy consumption of the ball mill.

Ultrafine grinding must be carried out using specialised equipment, specifically stirred media mills. Due to geometric limitations, tumbling ball mills have a small energy intensity, limited by the number of revolutions at which the grinding media is centrifuged in the mill wall (Celep et al., 2011). Attrition stirred mills are widely applied ...

Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]]. To produce the qualified size and high liberation of granule for the subsequent separation is the primary objective of the grinding operation [4,5].
