Nordberg C Series jaw crushers

Nordberg® C Series™ jaw crushers are engineered for the toughest feed materials. They are proven to be reliable and productive in thousands of real mining, quarrying, recycling and industrial applications. You can rely on the Nordberg C Series as the primary crusher of your process.

APPLICATIONS
Any demanding primary crushing application
Surface and underground applications
Stationary, portable and mobile installations
For hard rock, soft rock, gravel, recycling, industrial materials, slag, foundry waste

Features
The reliability of Nordberg® C Series™ jaw crushers is based on a revolutionary pinned and bolted, non-welded frame construction. This design provides excellent fatigue strength even in toughest quarrying or mining applications.

Nordberg C Series jaw crushers are the most productive and cost-efficient jaw crushers for any primary crushing application. C Series jaw crushers were originally developed to crush the hardest ores and rocks so they perform extremely well also in less demanding applications, such as soft rock, recycling and slag.

Metso’s foundry expertise enables continuous steel casting development to ensure the best casting designs and quality in terms of strength and fatigue life. High level of engineering combined with top-of-the-line commercial components, such as spherical roller bearings, ensure the reliability that Nordberg C Series jaw crushers are known for.

Benefits
High production
High reduction ratio
Easy maintenance
High uptime
The ultimate primary crusher

The Nordberg C Series jaw crushers are overhead eccentric single toggle jaw crushers. The feed material is crushed between fixed and movable jaw dies. Movable jaw die is mounted to the pitman. Pitman motion (=kinematics) is defined by the eccentricity of the eccentric shaft and by the angle of the toggle plate. In Nordberg C Series jaw crushers the angle of the toggle plate is so steep that it amplifies the stroke from the top of the cavity to the bottom of the cavity. The result is a long and linear stroke in the bottom of the cavity which ensures great productivity and high reduction ratio.

Cavity of the C Series jaw crushers works extremely efficiently from the very top to the bottom thanks to great feed opening dimensions, a good stroke up in the cavity, tight nip angle (angle between the fixed and movable jaw) and the long amplified linear stoke in the bottom of the cavity. The crusher size, weight, feed opening dimensions and capacity are all in good balance ensuring that with reasonable capital investment it is possible to process large feed and produce with good capacity. This ensures the best total economical feasibility of the primary crushing stage.
