The crushing rolls for primary and secondary crushers are made up of a roll body in polygon design which is equipped with exchangeable crushing segments. As a result of the specific geometry between roll body and crushing segment an optimum tight fit is achieved, thus being able to stand up to the high crushing forces

Jul 13, 2016 Jul 13, 2016 HPGR is typically used in a third-stage or fourth-stage crushing application ahead of grinding. You could always try to build a circuit doing 45 m classification, but I suspect your circulating load would be overwhelming. Most HPGR applications in hard rock mining achieve 3000 m to 7000 m product

Dec 16, 2015 Dec 16, 2015 The approximate capacity of a jaw crusher for hard rock application at a typical setting may be obtained by multiplying the width by 10 to get tonnes per hour. For example, a 48 by 60 crusher will have a capacity in the order of 600 tph when crushing ore in a hard rock mine. Source: Jack de la Vergne
