The CH cone crusher can be calibrated to achieve specific results, maximize productivity and minimize wear, but any calculation will be undermined without a solid understanding of what is going in to the crusher. Sampling is a vital part of the crushing process, to ensure that you know the size distribution of the feed.

The simulations indicate that even at much lower speeds, the performance of a double impeller impact crusher is exceedingly superior. However, the energy associated with the double impeller impact crusher is much higher and energy intensification, rather than energy efficiency, is the main gain of the double impeller design.
