Construction Technology introduces the Metso C120 jaw crusher – 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. The C120 was one of the new products
on display at Metso’s 2012 New Product Expo October 24-25 in Columbia, South
Carolina USA.

Metso has paid special attention to its new, durable and
user-friendly design for the C120. The casting design is based on thorough finite
element analysis (FEA) and casting simulations. Every detail of the C120 is
engineered
for reliable operation and long life, resulting in high,
constant crushing capacity and uptime.

Advertisment

“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,” says Ilkka Somero, Metso’s product manager for jaw crushers.

High productivity through long stroke and fixed jaw die

The high 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 x 47
" (1200 x 870 mm) and an aggressive cavity cross-section, resulting
in a high performance and reduction ratio.

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, thanks to its compact design,
and includes an optional integrated motor bed and guards. 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 3/4
"– 8" (70 – 200 mm). The operational weight is
57,200 lb (26,000 kg), excluding options.
