Increased production and energy efficiency for optimized ...
In order to achieve optimal performance of downstream processes with the finer ROM, a number of changes and adjustments were made to the crusher, SAG and ball mill circuits. The resulting mill throughput averaged 4,100 tph for the three trial blasts, and plant throughput above 4,500 tph was achieved for several hours during these trials.
Crushing in Mineral Processing
The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher's performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.

Impact Crusher Working Principle
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).
