Metso’s Mining and Construction Technology’s C120 jaw crusher is the 13th member of the C-series range of crushers. Metso’s C120 combines uncompromising reliability, crushing efficiency and versatility in both stationary and mobile applications with safety and ease of use.

“When starting the C120 project, we listened closely to our customers and collected field data from a number of sites. Based on that, we decided to design the crusher cavity and kinematics first. As a result, Metso can now offer aggregates producers, large-scale contractors and mining companies a new crusher that meets all the standards set for any demanding application,” said Ilkka Somero, Metso’s product manager of jaw crushers.

Productivity Through Long Stroke and Fixed Jaw Die

The productivity of the C120 is the result of several new design elements. The crusher features a long and aggressively directed stroke, and a fixed jaw die longer than previously seen in this crusher size class. The C120 has a large feed opening of 34 by 47 in. (86 by 119 cm) and an aggressive cavity cross section, resulting in a high performance and reduction ratio, according to the manufacturer.

In terms of cavity volume and crusher weight, the C120 is positioned between the existing Metso C116 and C125 jaw crusher models.

Easy to Install

The C120 is easy to install, due to its compact design, and includes an optional integrated motor bed and guards. Being well-balanced, the C120 is quick, easy and cost-efficient to install using rubber mounting pads underneath the crusher mounting brackets. No separate horizontal supports are needed. The crusher can be mounted in a variety of ways to ensure an easy fit onto an existing or new steel structure.

Mechanical or hydraulic setting adjustment systems are available for quick, easy and safe setting adjustment. For jaw dies, several cavity options are available. Depending on the customer’s preference, it is possible to use either single- or two-piece jaw dies.

Safety the Highest Priority

Safety is the highest priority for Metso when designing a new crusher. The C120 features optional robust 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 toggle plate, contributing to operational safety when changing wear parts.

The Metso C120’s nominal power is 200 hp (160 kW), operating speed 230 rpm, closed side setting between 2 ¾ to 8 in. (70 to 20 cm). The operational weight is 57,200 lb. (26,000 kg), excluding options.
