Metso introduces the Nordberg GP7 secondary crusher

November 24, 2014 – Metso continues to expand its range of
high capacity crushers by launching Nordberg GP7, its largest Nordberg GP
secondary gyratory crusher to date. The new 58-ton (128 000 lbs) crusher
features a combination of feed opening, cavity design and capacity available on
the market. This ensures high crushing performance with even the hardest feed
and helps maintain operational costs low. In addition, the crusher is safe to
operate and maintain.

and helps maintain operational costs low. In addition, the crusher is safe to
operate and maintain.

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 450 mm (18"), 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 translate into predictable revenue and excellent
process throughput.

High power meets flexibility

Nordberg GP7 has seven strokes available as standard. The
possibility to select a suitable combination from the strokes (25 – 50 mm, 1 –
2") ensures perfect adaptability for any application.

The steep cavity and easily changeable stroke ensures high
performance when using a power rating as high as 550 kW. In fact, Nordberg GP7
has the highest power rating in its size class. And thanks to the robust design
specific to Nordberg GP, the GP7 adapts for 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 tools required for safe maintenance work. Process control is based on an
advanced Metso IC automation that provides easy, safe, and trouble-free
operation.

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