Nordberg® GP7™ secondary gyratory crusher fits to your process ideally
The Nordberg® GP7™ secondary gyratory crusher has been developed to crush feed materials efficiently, reliably and economically. With 560 kW (750 hp) power and 61 tonnes (135 000 lbs) of weight, Nordberg GP7 has the highest performance in its weight class.
Nordberg GP7 can easily be configured to work efficiently with the rest of the crushing plant thanks to the number of strokes available. The robust design of the crusher guarantees that Nordberg GP7 adapts to varying operation and on/off feed conditions. In addition, the excellent capacity of Nordberg GP7 is the result of a constant feed opening, efficient stroke and steep cavity.
Due to the fact that Nordberg GP7 allowed power is clearly bigger than of Symons 7’, the increased energy is used for making your end-product curve finer. Finer and well prepared end product curve already after secondary crusher means better feed for the downstream process, ie. the next crushing and screening stage. In mining, crushing finer reduces the costs of grinding for instance.
Compact dimensions, custom-made support legs and the identical footprint compared to Symons 7’ makes Nordberg GP7 ideal for upgrade/replacement installations.
Replacing the Symons 7' with Nordberg GP7 secondary gyratory crusher will increase your crushing plant's productivity. Nordberg GP7 can process more ore to the same reduction or the same quantity of ore to a finer reduction than Symons 7'. Nordberg GP7 is designed to fit onto a Symons 7' cone crusher foundation and it has exactly the same footprint. That translates into higher productivity with substantial savings in plant modifications or building and foundation costs.
