Nordberg C150 jaw crusher

The heavy duty Nordberg C150 jaw crusher is designed without compromise to be the leading jaw crusher in the 50 ton weight class. The unit has been developed for the most demanding large scale mining and quarrying applications. The great feed opening with long steep crushing cavity allows large coarse feed material up to one meter (40”) size.

The highest long-term performance and reliable design
Features
Nordberg® C150™ jaw crusher offers outstanding performance in terms of operating lifetime and its ability to crush large feed material to required product sizes at high capacity rates. An extended feed opening not only accepts material up to one meter (40”), but also easily breaks it by the increased stroke at the top of the cavity. The tight nip angle in the middle of the cavity ensures the material is quickly transferred to the bottom of the cavity where the legendary Nordberg C jaw’s long stroke finishes the job.

Like all C series jaw crushers the Nordberg C150 is built out of premium quality components. The main frame structure is based on unique pinned and bolted connections without welded seams, the way only Metso can do it.

Safe to operate and maintain

The Nordberg C150 is engineered for safe operation and easy maintenance. There are limited number of service points, all with easy and safe access.
The operation, condition monitoring and greasing can be fully automated. Lifting tools for components are supplied as standard to ensure the safest possible maintenance procedures.

Easy to install

The modular design enables wide range of bolt on options like motor base, feed chute and composite guards. Multiple installation alternatives from low profile to surface installation either on steel or concrete structure are possible. The Nordberg C150 can be dismantled for transport and reassembled for example on the underground site if preferred.

Process overview

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.
