cone crusher / gyratory / stationary / secondary

The Nordberg GP7’s process throughput is the result of constant feed opening combined with its steep cavity. The cavity and easily changeable stroke ensures high performance when using a power rating as high as 560 kW (750 hp). Long lasting liners, efficient adjustable stroke and large setting range bring optimal use of high power. The feed opening of 450 mm (18”) remains constant throughout the liners’ lifetime. The constant feed opening is one of the most significant benefits of this 61 tonne (135 000 lbs) secondary gyratory crusher.
