Gyratory crushers are identified by the size of the gape and the size of the mantle at the discharge. They range in size up to ca. 1,600 mm×2,900 mm (gape×mantle diameter) with power consumption as high as 1,200 kW and capable of crushing up to ca. 10,000 t h −1 at a discharge open side setting up to 240 mm.
