Energy Use Of Fine Grinding In Mineral Processing
Fine grinding, to p80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. this grinding is typically done using stirred mills such as the isamill or stirred media detritor. while fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mills energy budget. overall energy use and media.

The results of the xrd study of the mechanochemically activated kaolinite have implications for mineral processing of kaolinite. the study shows that there is an optimum time for grinding. too little grinding results in large particle sizes with low surface areas; there is an optimum grinding time for maximum surface area of the kaolinite; too.
Implications Of Fine Grinding In Mineral Processing
Fine grinding of minerals may change physical and chemical properties of the material to the extent that has to be considered in laboratory verification work or processing work in the industrial plant. the ground material is mechanically activated by increase of both: specific surface energy and elastic strain energy. the activation energy can then be dissipated through different mechanisms.
