The 550 kilowatt, 58 tonne machine includes a steep cavity and a choice of seven strokes ranging in size from 25-50 millimetres for increased adaptability.

It also features a 450mm feed opening that remains constant throughout the lifetime of the liners, reportedly ensuring steady performance and stable end-product quality.

"[This] translates into predictable revenue and excellent process throughput," Metso said.

Nordberg GP7 can be fed with a large primary crusher such as the Nordberg C200 jaw crusher or Nordberg SUPERIOR primary gyratory crusher - followed by a Nordberg HP6 cone crusher for tertiary crushing applications.

The machine is operated through an advanced automation system and features a limited number of service points. Maintenance and service tools are delivered standard with the machine.

According to Metso, the Nordberg GP7 secondary gyratory crusher boasts the same footprint as the previous Nordberg Symons 7 foot cone crusher (and other similar crushers) making upgrades easy.
