Abstract Unconfined Compressive Strength (UCS) is a commonly used rockmass strength (WiC) for coarse rocks (75-50 mm), a rod mill work index (WiRM) for analysis of energy consumption of crushing processes - De Gruyter Key words: rock crushing, jaw crusher, crushing efficiency, two stage crushing Strength parameters of the feed (Ak-

Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them Impact crushing can be of two variations: gravity and dynamic An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill)
