A new jaw crusher range brings a diesel-electric power line to the aggregates market.
Working with hard rock aggregates and recycling materials requires raw force in demanding conditions. It is also essential that high-quality products are produced on time, at the right price. To meet these targets, Finnish company Metso’s new Lokotrack EC range claims to boost reliability and performance.
Metso recently launched the first two products of its new EC range (at the Lokolaunch event in Tampere, Finland in April this year), the Locotrack Mobile Cone Crusher LT350C and the Locotrack Jaw Crusher LT400J. The LT400J comprises a 68-tonne mobile jaw crusher designed for the primary crushing of hard rock and recycled aggregates. The LT350C is a 50-tonne mobile cone crusher for secondary and tertiary crushing. To reach high capacity, LT350C comes equipped with the new Nordberg HP350e cone crusher, while LT400J relies on the proven Nordberg C120 jaw crusher. Both units can be seamlessly combined with each other as well as with the Lokotrack mobile screens to produce high-quality aggregates.
“When external electricity is available, the new electric power transmission provides high capacity with minimised operational cost and CO2 emissions. When not available, the onboard diesel gensets allow maximum independent operation time. In addition, auxiliary units, such as mobile screens and stackers, can be powered from the same gensets, which will further reduce the needed power to run the complete plant,” says Jarmo Vuorenpää, director of the new Lokotrack offering at Metso.
A modular design
The Lokotrack EC range has been developed using new, modular architecture, which reduces the number of components and provides scalable solutions that can be adapted for different applications and capacities. “This modular architecture enables a faster, more agile way of creating products and meeting changing customer needs. Furthermore, it enables more efficient support for the machines with fewer parts needed and easier feature upgrades,” says Renaud Lapointe, senior vice president of Metso Products business line in the Aggregates business area.
Safety standards
All the components of the new EC range are designed and tested to perform in demanding conditions and reach maximum uptime for the customers. Safety and usability have been given special attention. The LT400J and LT350C meet the latest safety standards while being user friendly. The units can be operated safely from the excavator and be quickly set from transport to operation.
The concept of track-mounted crushers and screens was developed in Finland in 1985 to minimise cost and energy use, and the associated Lokotrack units help process both natural aggregates and recycled materials. Lokotrack EC, the new diesel electric range (launched at the company’s recent event) complements the company’s existing offering.
