Metso introduce new Nordberg C150 jaw crusher

New crusher designed to accept coarsest feeds thanks to large feed opening and extra-tall cavity

A LARGE feed opening that allows even the coarsest feed to enter the crusher is one of the key user-friendly features of Metso Mining and Construction’s new Nordberg C150 jaw crusher. This combined with an extra-tall cavity ensures constant high capacities in any demanding large-scale quarrying and mining application, say the manufacturers.

Offering reliability, crushing efficiency and versatility in stationary, mobile and portable applications with safety and ease of use, the Nordberg C150 jaw is the newest member of the field-proven C-series range of crushers, built since 1975 as more than 10 different models.

‘We have designed this crusher especially for mines and large quarries. This product is the answer to our customer’s wish for a primary crushing process that is able to handle even the coarsest feed and maintain a trouble-free material flow through the crusher,’ said Ilkka Somero, Metso’s product manager for jaw crushers.

The cavity depth of the C150 is 1,200mm (47in) – a figure more commonly seen on bigger jaw crushers. This combined with the large feed opening width allows feed sizes up to 1,000mm (40in) to enter the cavity.

Other new C150 design elements include proven open back pitman casting technology, which improves strength thanks to long ribs placed in two directions. The machine’s outstanding capacity is also ensured with increased main shaft eccentricity and an improved nip angle due to a longer fixed jaw. Similar to other well-balanced C-series jaws, the C150 is quick and easy to install, thanks to its compact design, and includes an optional integrated motor base and guards.

Safety is the highest priority for Metso when designing a new crusher, and the C150 is now exception. It features optional robust composite flywheel guards that allow quick and safe access to all service points, and the standard delivery includes lifting tools for jaw dies, cheek plates and toggle plate, thereby contributing to operational safety when changing wear parts.

For C150 jaw dies, several cavity options, including quarry, thick quarry and super grip, are available. Depending on the customer’s preference, it is possible to use either single- or two-piece jaw dies.

With an operational weight of 51,300kg, excluding options, the Nordberg C150’s offers closed-side settings between 125–250mm (5–10in) and has a nominal power output of 200kW (300hp) and an operating speed of 220 rev/min.
