A client needed finer crush out of his Jaw Crushers.  I proposed this literature from Metso.com to help him select a jaw liner set.  Designing your jaw crusher liners for the right function starts with asking ‘what final product crush size distribution do I want’ & ‘what are the physical characteristics of the feed to that crusher’?  Look at the table below to make you assessment and design decision.
