·Then all material leaving that crusher with a 1 in setting would be of a minus 1 in size Another possible solution to this problem would be to use a gyratory crusher for the primary crushing stage A gyratory like Telsmith model 1110 could be set at 1½ in in an open circuit with a capacity for 260 tph
·design and operating principle Technical data Single toggle jaw crusher Design Single toggle jaw crushers are characterized by the swing jaw being suspended directly on the eccentric drive shaft and the lower part of the swing jaw being braced against the crusher frame by means of a toggle plate
Gyratory crushers are principally used in surface crushing plants The gyratory crusher Figure consists essentially of a long spindle carrying a hard steel conical grinding element the head seated in an eccentric spindle is suspended from a spider and as it rotates normally between 85 and 150 rpm it sweeps out a conical path within the fixed crushing
·A gyratory crusher has a mantle that rotates within a concave bowl while a cone crusher has a mantle that rotates within a bowl shaped concave This design allows for a larger feed size and a higher capacity for both types of crushers but gyratory crushers are typically designed for high capacity crushing whereas cone crushers are intended
