metsorockbreakerFebruary 26, 2014 – Metso Mining and Construction's product
portfolio is expanding with the addition of a new rock breaker series designed
for primary stationary crushing stations.

The hammer-boom combination, already well known in Metso's
mobile solutions, is now available for stationary aggregates production and
mining applications.

Rock breakers are commonly used in primary crushing stations
to break oversized boulders that are fed into the crusher and to clear clogging
in the cavity. Today, most of the primary stations use this combination to
guarantee smooth, continuous performance and to minimize idling caused by
build-ups and blockages.

 

"Today, safety at work is undeniably the number one
issue within the construction and mining industries. The remotely controlled hammer-boom
combination provides, without a doubt, the safest solution for clearing clogged
crusher cavities," comments Ilkka Somero, Product Manager for Metso rock
breaker solutions.

 

Earlier, Metso did not have its own hammer and boom
combination available for stationary primary crushing stations. Based on
customer demand, Metso was asked to provide a solution to meet this need.

 

"We have now introduced a range of breaker boom and
hammer combinations and can offer our customers a complete turnkey solution.
Besides the requested primary crusher, Metso can now offer a comprehensive
breaker attachment: a boom with assembly framework, hammer, related hydraulic
power pack and remote radio controls," Somero adds.

 

The new Metso MH-series hammers and MB-series booms include
five boom-hammer combinations for jaw crushers and one for primary gyratory
crushers.

 

The hammer weights range from 400 kg (880 lbs) to 2200 kg
(4840 lbs) and the corresponding power ratings from 18 kW (25 hp) to 45 kW (60
hp).
