THE UK’s first Powerscreen Premiertrak 600 mobile jaw crusher has gone to Malcolm Construction Services.
Supplied by Blue Machinery Scotland, the powerful crushing plant has been put to work with other Powerscreen equipment, processing quarried basalt at Malcolm’s Loanhead Quarry in Beith. The firm has also bought a new 1150 Maxtrak cone crusher to achieve type 1 sizes for drainage and concrete aggregate.
The Premiertrak 600, recently introduced by Powerscreen, offers throughput of around 600 tonnes per hour. Described as “quick and easy to set up” it is said to be robustly engineered for high production quarrying and recycling applications – and is especially suited to processing hard rock.
The 1200mm X 820mm jaw chamber incorporates features such as a fully hydraulic CSS range of 75mm – 200mm and a reversing system to clear blockages quickly. The high capacity jaw is fed by a vibrating grizzly feeder with variable speed control and a large grizzly area to maximise removal of fine material, thereby prolonging the wear life of jaw plates within the crusher chamber. The bypass chute is also fitted with wear-resistant liners as standard, and incorporates an adjustable five-position deflector plate to divert material to either the product or side conveyors. The product and tail conveyors can be raised and lowered hydraulically. The controls incorporate a modern interface with intuitive graphics and high resolution display for ease of operation. There is automatic start/stop and diagnostic and machine adjustment capability. The speed of the jaw crusher on the Premiertrak 600 can be varied to suit the application and feed materials.
Freddie McAlister, Malcolm Construction Services’ Plant Manager at Loanhead, said, “We chose this new generation Premiertrak 600 because we have successfully used Powerscreen machines for many years and know their excellent build quality, reliability and proven longevity. We also like the independent live pre-screen on this new machine, which allows us to extract lower quality -40mm scalpings during the process.”
