Optimizing Performance of SABC Comminution Circuit of

In 1990s, during the design of the Wushan SABC circuit comminution stage, the only information available was the Bond work index, which was calculated with insufficient ore comminution characteristics testing and semi-industrial testing [3,4,5]. This was due to the lack of research in this field in China and the lack of knowledge in SABC circuit design. The sizing of the processing equipment

comminution circuits. The innovative work of Michaux on breakage patterns observed in rocks broken through blasting linked neatly into this, as the fragmentation picture became clear in terms of surface area, rather than size. Michaux emphasised the importance of the distribution of shape within a size interval 9rather than an average shape property). Based on this he showed the self-similar

Comminution | Centre for Minerals Research

Comminution: Comminution utilises energy to reduce the size of ore particles in order to liberate embedded mineral grains so that they can be recovered in the subsequent process stages. The research under this theme focusses on understanding how energy is used in devices that use different breakage mechanisms to achieve size reduction and how energy is utilised in different comminution circuit

Comminution : ALS

ALS comminution process development testwork, at both laboratory and continuous pilot plant scales, minimises the technical risks associated with the development of comminution circuits. Crushing and grinding of ores is a significant capital and operating cost in many mineral processing plants, and up to fifty percent of the operating costs can be attributed to crushing and milling alone.

Production improvement opportunities in comminution

The operation of comminution circuits to known and accepted standards, which is explained in this paper, could improve the performance of circuits by between 5 and 10 per cent, generally at no capital cost and often at a lower operating cost. The performance improvement can be realised as throughput increase, a finer product size, or reduced operating costs (ie, energy saving, low maintenance
