The layering can result in preferred breakage planes as indicated by Lindqvist Åkesson and Malaga [84] which may explain the significative influence of the crusher type for this aggregate The jaw crusher generated more blade shaped particles compared to the roll crusher For the roll crusher more disc shaped particles were generated
The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above To have a feed opening corresponding to that of a jaw crusher the primary gyratory crusher must be much taller and heavier Also primary gyratories require quite a massive foundation Primary crushing with impact crushers
The Crunchy© crusher is credited with a maximum production of m 3 /h of crushed aggregate In what follows we assume a reduced value of m 3 /h = h/m 3 that best fits a continuous production procedure all day long; we assume that m 3 of aggregates is needed for 1 m 3 of concrete; and the crusher cost per hour is assumed to be
