Developed on the basis of true field experience
Nordberg® C120™ jaw crusher has been developed on the basis of field experience from customer sites. Crusher cavity, kinematics and operating parameters have been defined and optimized to guarantee the excellent productivity for which Metso C Sereis jaw crushers are known and valued. Crusher height utilization has been optimized to give the steepest possible cavity cross-section. Excellent nip angle high up in the cavity, together with an aggressive linear stroke at the bottom, ensure high throughput capacity and reduction. Outstanding reliability combines with excellent productivity to give the lowest cost per produced ton of end product.
Easy to install
The C120 has a range of bolt-on options, including an on-board motor base, and guarding for the flywheel and drives made from specially developed composite materials, which makes the unit simple to install as a crusher only or as a complete module in a new or existing plant. The crusher is mounted without bolts between crusher and structure using mounting pads, which absorb the dynamic forces thus reducing the dynamic loads transmitted to the structures underneath.
Safe to operate and maintain
Nordberg C120 jaw crusher is designed to be safe to operate and maintain. There are a limited number of service points and they can be accessed easily and safely. Lifting tools for items such as jaw dies, cheek plates and the toggle plate are supplied with the crusher to guarantee safe maintenance procedures and to ensure the safety of both crusher operators and maintenance crew.

Nordberg C Series jaw crushers are most commonly used as primary crushers, to make the first step of size reduction. In some cases the jaw crushers is used to produce final end product but in most cases the jaw crusher is used to prepare the feed for the secondary crusher in a crushing and screening process.
How it works
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.
