At ConExpo earlier this year, Metso launched their new LT7150 crushing plant with Bar-mac vertical shaft impactor (VSI) technology. The Lokotrack LT7150 mobile VSI plant is designed for final stage crushing for producing high-quality cubical aggregate, road base and prime manufactured sand.
Key features include ease of use thanks to advanced crusher automation, the option of step-less control of product grading, and the option of using the unit seamlessly as part of a two- or three-stage Lokotrack crushing and screening process. The new VSI-Lokotrack is built around the Barmac B-Series vertical shaft impactor which features rock-on-rock crushing action. The Barmac VSI’s 840 DTR rotor accepts feed sizes up to 2.6 inches (66 mm), accelerates material and continuously discharges into the crushing chamber. The crusher runs on a direct hydraulic motor, which eliminates the need for V-belts and enables fully adjustable tip speed using an automated control panel. Additionally, the LT7150 is fitted with a metal detector and can be fed by conveyor, excavator or wheel loader thanks to the large, 6.5-cubic-yard (five-cubic-metre) feed hopper, while the sturdy belt feeder (6,000 mm by 1,000 mm) takes infeed to the crusher. Units are powered by an efficient 415-hp (310-kW) Cat C13 Tier III diesel motor.
