Metso jaw crusher features increased cavity volume.
Metso's new Nordberg C130 jaw crusher can process more rock in the crushing process, owing to a larger cavity volume that helps deliver higher production in high-capacity primary crushing, according to the company. The machine is targeted to demanding quarrying and mining applications.
The cavity volume of a jaw crusher has a big impact on the efficiency of the crusher. The Nordberg C130 jaw crusher has a 21 percent larger cavity volume in comparison to previous models in this size class. The larger cavity volume means that more rock or ore is in the crushing process at one time.
The C130 is a 40-ton jaw crusher and features Metso's pinned and bolted design for reliability, long life and easy service. Reliability, crushing efficiency in stationary and mobile applications, uncompromising safety and ease of use have been the key parameters while designing this jaw.
"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 percent more material increasing crushing capacity significantly," said Ilkka Somero, Metso's product manager for jaw crushers.
Large Feed Opening Saves Blasting Costs
The large, 39- x 51-in. 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, the company said. This results in savings in blasting costs and allows the processing of coarser feed at the primary stage.
"This new design combined with a 160kW [200-hp] power range, a small nip angle and excellent kinematics ensures aggressive crushing along the whole length of the crusher cavity" Somero added.
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 is one of the key focus areas for Metso when designing a new crusher. The C130 features optional, easy-to-open composite flywheel guards that allow quick and safe access to all service points. The standard delivery includes lifting tools for jaw dies, cheek plates and a toggle plate, all contributing to operational safety.
Easy to Customize with Options
The Nordberg C130's operating speed is 220 rpm and the closed side setting between 4 and 10 in. The operational weight is 88,500 lb., 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 a boom combination, and an IC1000 process automation package.
