Optimized cavity volume

The new Nordberg C130 jaw crusher has just raised the bar: thanks to an improved combination of cavity volume and crusher kinematics compared to previous models in the C-class, primary crushing in demanding quarrying and mining applications is rewarded with a higher throughput rate (Fig. 1).

The cavity volume of a jaw crusher has a big impact on the efficiency of the crusher. Metso’s Nordberg C130 jaw crusher has a 21-%-larger cavity volume in comparison to previous models in this C-class. The larger cavity volume means that more rock or ore is in the crushing process at one time without any problems. The increased volume combined with the extra large feed opening ensures much higher 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 launch of Nordberg C130, Metso launched the all-new Nordberg C120 and C150 jaw crushers.

The new C130 is a 40-tonne jaw crusher in terms of operating weight and features the famous pinned and bolted design for reliability, long life and easy service. Reliability and crushing efficiency in stationary and mobile applications as well as uncompromising safety and ease of use have been the key parameters in the development of the new series.

“Our C130 really stands out of the crowd with its bigger cavity volume. 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,” comments Ilkka Somero, Metso’s Product Manager for jaw crushers.

“This new design combined with a 160 kW power range, a small nip angle and excellent kinematics ensures aggressive crushing along the whole length of the crusher cavity,” Ilkka Somero says. Thanks to the compact design, older crusher models can be easily replaced with the C130. The pinned and bolted design also makes it possible to disassemble the C130 and transport it even to the deepest underground mines.

Safety for the employees in operation and maintenance is a key focus in the Nordberg C130: the jaw crusher features optional, easy-to-open composite flywheel guards that allow quick and safe access to all service points (Fig. 2). The standard delivery includes lifting tools for jaw dies, cheek plates and a toggle plate.

Easy to customize thanks to interesting options

In addition to the composite guards, the new Nordberg C130 can be customized to any application and installation situation with optional components. The selection includes, for example, a wear-protected feed chute, an integrated motor bed with electric drive, a hydraulic gap adjustment, a rock breaker and a boom combination and an IC1000 process automation package, just to mention a few of the optional extras.

Other key technical specifications: the Nordberg C130’s operating speed is 220 rpm, the gap width can be adjusted very easily between 100 and 250 mm. The operational weight is 40 100 kg (excluding any optional components).
