Metso continues to expand its range of high capacity crushers by launching the Nordberg GP7, its largest Nordberg GP secondary gyratory crusher to date. The new 58-ton (52 t) crusher features an optimal combination of feed opening, cavity design and capacity. This combination ensures high crushing performance, even with the hardest feed, and helps keep operational costs low. In addition, the crusher is safe to operate and maintain, according to the manufacturer.

Nordberg GP7 is well suited for both mining and aggregates applications. It can be fed with a large primary crusher such as the Nordberg C200 jaw crusher or Nordberg SUPERIOR primary gyratory crusher, and followed by a Nordberg HP6 cone crusher for tertiary crushing.

Constant Feed Opening Offers Significant Advantages

The Nordberg GP7 secondary gyratory crusher features a large feed opening of 18 in. (45.7 cm), which remains constant throughout the lifetime of the liners. This is one of the most significant benefits of the new crusher. The constant feed opening ensures steady performance and stable end-product quality, which translates into predictable revenue and excellent process throughput.

High Power Meets Flexibility

Nordberg GP7 has seven strokes available as standard. The ability to select a suitable combination from the strokes — 1 to 2 in. (2.5 to 5 cm) ensures perfect adaptability for any application.

The steep cavity and easily changeable stroke ensures high performance when using a power rating as high as 740 hp (550 kW). In fact, Nordberg GP7 has the highest power rating in its size class, according to the manufacturer.

Due to the robust design specific to Nordberg GP, the GP7 adapts to varying feed conditions.

Safe to Operate and Maintain

The limited number of service points can be accessed safely and easily. As with all Nordberg GP crushers, Nordberg GP7 is delivered with all of the tools required for safe maintenance work. Process control is based on an advanced Metso IC automation system that provides easy, safe and trouble-free operation.

The Nordberg GP7 secondary gyratory crusher has exactly the same footprint as the Symons 7 ft. and similar crushers, which makes replacement of an old crusher very easy.
