Crushing Plant Flowsheet & Design-Layout
Through proper application of the Gyradisc crusher, mill feeds of 100 percent passing 3, 4, and 6 mesh are attainable. The crushing action of the Gyradisc crusher results in circulating loads of less than 50 percent of the new feed rate when closed circulating on 3 mesh, to 150 percent when closing the circuit on 6 mesh.

Modelling SAG milling power and specific energy
For a given mill to have a combination of feed size, ball load, mill speed and % solids will represent the total load. In fact the later can be modelled as a function of the others. Additionally, as has been shown by Powell et al. (2001), ball loads high enough (over 12% as in the cases studied in this work) contribute to a significant portion ...
