Problems A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h The largest size of the run of mine ore was 1000 mm A gyratory crusher 122 cm × cm required 300 HP to operate at a gyration of 135 cycles/min When the eccentric throw was cm and open side setting was cm it produced 1023 t/h
The Gyratory Crusher is made up of six main components Base Main frame and concave liners Drive assembly Mantle Spider arm assembly Oil The base is the section of the crusher that provides an entry point for the drive assembly and oil system
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
