Mellott Company recently became the first in the United States to try Metso’s new rock breaker solutions, installing the boom-and-hammer attachment on its Lokotrack LT116 mobile jaw plant. Mellott Company has been a Metso distributor since 2000, providing new equipment sales and rentals, engineered systems, spare and wear parts, and comprehensive field and shop services. Mellott also provides a wide range of small- and large-volume contract crushing services to its customers, utilizing Metso’s complete range of Lokotrack track-mounted crushing plants. Mellott is using the Lokotrack LT116 primary jaw plant, with Metso rock breaker attachment, at contract crushing jobs in the eastern United States.

Safest Way to Manage Build-Ups

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

Metso recently expanded its product portfolio with the addition of a new rock breaker series designed for primary stationary crushing stations. The hammer-boom combination, already well known in mobile solutions, is now also available for stationary aggregates production and mining applications. The remote-controlled rock breaker boom and hammer, with radio remote control, is part of Metso’s standard scope of supply. This means that the boom and hammer can be operated from a safe location that gives the operator unlimited visibility into the area where the rocks are moved or broken. Metso rock breaker solutions also are engineered to be safe and easy to maintain, with single-point lubrication of the boom joints as a standard feature, according to the manufacturer.

“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 of Metso rock breaker solutions.

In addition to safety considerations, production also is significantly increased when the primary mobile or stationary crushing plant is equipped with a rock breaker. Downtime due to build-ups and blockages can be easily kept to a minimum. These factors came into play when Mellott Company added the Metso rock breaker to its LT116 jaw plant.

“These rock breakers increase production and decrease downtime, helping to keep the LT116 operating at maximum performance, which is critical to profitability in contract crushing jobs,” said Jim Levy, operations manager of Mellott.

“Of course, everyone is familiar with Metso’s crushing and screening equipment, but the rock breakers are not so well known,” said Scott Yablonsky, Metso distributor manager, Atlantic USA. “We’re very pleased that we can now offer customers a complete Metso rock breaker solution that is designed to work efficiently with the Metso primary crushers.”

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 880 lb. (400 kg) to 4,840 lb. (2,200 kg) and the corresponding power ratings from 25 to 60 hp (18 to 45 kW).
