Hammer and boom combination available for stationary primary crushing stations

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 minimise idling caused by build-ups and blockages.

Metso Mining and Construction's 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. 

“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,” said 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 2200kg (4840lbs) and the corresponding power ratings from 18kW (25hp) to 45kW (60 hp).
