But keep in mind crushing (as Natasha will probably assert as well) has more to do with jaw opening then anything. A 2 x 2 foot jaw crusher set at 1 inch is going to be slow, where as a 12 x 12 inch jaw crusher set at a 4 inch opening is going to be 10 times faster. The other part of crushing, is how good the grizzly is.
