Rittinger's theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: "The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of ...
A typical ore body will contain a few percent of ore minerals—typically sulphide minerals like chalcopyrite or sphalerite—along with the minerals of the original rock (e.g., quartz, feldspar, amphibole etc.). Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2 ).
This paper assesses a number of factors affecting the performance of the crushing plant by addressing the critical design parameters and consideration of ore characteristics, operability and maintainability. Due to the fact that ore properties remain the same during milling, its control may become difficult for yield and quality of a product.
