Gyratory crushers differ from cone crushers with regard to their design. In contrast to the cone crusher, which has a fixed shaft on which the power supply unit and the head rotate, the gyratory crusher has a main shaft that can be moved hydraulically in vertical direction on which the head is permanently shrink-fitted.
