Building on more than 20 years of experience with the Lokotrack mobile crushing concept, Metso Minerals has unveiled an entirely new generation of mobile plants for primary crushing.
The Lokotrack LT3054, LT1315 and LT1415 combine continuous high crushing capacity, a broad range of process options and user-friendly operation with the latest dust and noise reduction options.
Metso Minerals chose the Nov. 15 opening of its new production facility in Columbia, S.C., for the North American introduction of the new Lokotracks.
The new generation Lokotracks are practical for both high-capacity contract crushing and the most demanding quarrying and in-pit crushing applications. Due to the low transport height, the units can be transported on a standard trailer. When equipped with the optional over band magnetic separator and pan feeder below the crusher, trouble-free processing of recycled materials containing rebar is possible, according to the manufacturer.
With a capacity range of up to 1000 tons (900 t) per hour, the new Lokotrack models can be used for any single- or multi-stage primary and secondary crushing process. They have operating weights from 60 to 70 tons (54 to 63 t), and are powered by Tier III Caterpillar diesel engines.
The original Lokotrack product line has expanded to more than 30 different models with more than 3,000 units delivered world wide.
The new Lokotracks are built around the Nordberg C Series jaw crushers and NP Series impact crushers. The C Series crushers are designed for primary reduction of hard and abrasive materials.
The NP Series impact crushers are capable of crushing medium hard rock types, such as limestone, as well as all rock-based recycled materials. The NP crushers feature a large feed opening to avoid bridging, a triple-wedge hammer retention system for simple and quick locking of wedges, and heavy-duty construction for a long and reliable service life.
The new Lokotracks can be equipped with several feeder options: a high capacity grizzly (LT3054), a pan feeder/scalper (LT3054, LT1315, LT1415) or a roller grizzly (LT3054, LT1315, LT1415) capable of handling highly viscous feed materials.
The new Lokotrack models can be equipped with the optional two-deck screen and product conveyors. This enables production of one or two calibrated end products. When equipped with the circulation conveyor, the screen oversize fractions can be returned to the crusher.
Other key features include the IC700 intelligent control system that optimizes the crushing process for improved performance and product quality, easier operation and enhanced serviceability. A detachable screen module with two decks that offer the facility for closed circuit operation and the ability to produce a number of different end products, is available as an option.
