The mobile crushing plant is now at work processing quarried Basalt at Malcolm’s Loanhead Quarry, Bieth near Glasgow, which the company acquired in 2006.
Both machines were supplied by Blue Machinery Scotland.
The Premiertrak 600, recently introduced by Powerscreen, is a primary jaw crusher, offering a throughput of around 600 tonnes per hour. The 1200mm x 820mm jaw chamber has a fully hydraulic CSS range of 75mm to 200mm and a reversing system to clear blockages. 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, prolonging the wear life of jaw plates within the crusher chamber.
Malcolm plant manager Freddie McAlister 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.”
