Higher-capacity primary crushing from Metso
The new Nordberg C130 jaw crusher offers higher production due to 20% increase in cavity volume
THE cavity volume of a jaw crusher has a big impact on the efficiency of the crusher, and the Nordberg C130 jaw crusher, recently introduced by Metso, is said to have a 21% larger cavity volume in comparison to previous models in this size class.
This larger cavity volume means that more rock is in the crushing process at any one time and when combined with the extra-large feed opening ensures high-capacity primary crushing in all demanding quarrying and mining applications.
The introduction of the Nordberg C130 jaw crusher continues the renewal of Metso’s proven, mid-size and large jaw crushers. Prior to the introduction of Nordberg C130, Metso launched the all-new Nordberg C120 and C150 jaw crushers.
The new C130 is a 40-tonne jaw crusher featuring the renowned pinned and bolted design for reliability, long life and easy service. Reliability and crushing efficiency in stationary and mobile applications, as well as safety and ease of use, were key parameters in the design of the new crusher.
‘Our C130 really stands out from the crowd with its bigger cavity volume,’ commented Ilkka Somero, Metso’s product manager for jaw crushers. ‘In fact, the cavity is larger in all three dimensions – deeper, wider and longer. Consequently, the new cavity can process over 20% more material, increasing crushing capacity significantly.’
The large, 1,300mm x 1,000mm (39in x 51in) feed opening of the C130 jaw crusher is able to process even the coarsest feed and maintain a trouble-free material flow through the crusher, resulting in savings in blasting costs and allowing the processing of coarser feed at the primary stage.
‘This new design combined with a 160kW (200hp) power range, a small nip angle and excellent kinematics ensures aggressive crushing along the whole length of the crusher cavity,’ Mr Somero added.
Thanks to its compact design, older crusher models can be easily replaced with the C130, while its pinned and bolted design also makes it possible to disassemble the new crusher and transport it even to the deepest underground mines.
Safety is one of the key focus areas for Metso when designing a new crusher, and the C130 is no exception. It features optional, easy-to-open composite flywheel guards that allow quick and safe access to all service points, while the standard delivery includes lifting tools for jaw dies, cheek plates and a toggle plate, all of which contribute to operational safety.
The Nordberg C130’s operating speed is 220 rev/min and the closed-side setting can be varied between 100mm and 250mm (4in to 10in). The crusher’s operational weight is 40,100kg, excluding options.
In addition to the composite guards, the new C130 can be customized to any application with options such as a wear-protected feed chute, an integrated motor bed with electric drive, a hydraulic setting adjustment, a rock breaker and boom combination, and a IC1000 process automation package, among others.
