Rock Crushing Rule of Thumb Mineral Processing & Metallurgy

The desired grizzly opening for an underground jaw crusher is equal to 80% of the gape of the crusher. Source: Jack de la Vergne; The maximum feed size for a jaw crusher should be about 85% of the gape. Source: Arthur Taggart; The combination of a jaw crusher and a scalping grizzly will have 15% more capacity than a stand-alone jaw crusher.

Crusher Efficiency Calculations

The specifications and manufactured limitations, rather than economy, generally govern the selection of crushers. To find the required areas of screen, the rate of feed of material as well as gradation of the feed must be known.
