Powerscreen launch new screens at Hillhead 2014
Powerscreen used the recent Hillhead 2014 show to launch their new Powertrak 750 machine, a robustly constructed, multi-purpose scalping screen geared towards heavy-duty scalping duties in applications such as blasted rock, overburden and C&D waste, although the machine’s lively screening action is said to lend itself equally well to fine screening applications with materials such as crusher run and topsoil.
The Powertrak 750 screen features a Deutz D914 engine as standard but can also be supplied with a fuel-efficient Stage IV Final-compliant Cat C3.4 engine.
With its vibrating-grid feed-in width of 4.4m (14ft 6in), the Powertrak 750 (pictured) can easily be fed by an excavator, loading shovel or grab. Powerscreen say this, coupled with its compact design and ease of movement, makes the screen a suitable choice for contractors, quarry operators and recycling customers alike.
Hillhead 2014 also saw the UK launch of the new Warrior 2100 screen featuring Powerscreen’s proven triple-shaft technology. First developed for the successful Warrior 2400 screen, triple-shaft technology, which is unique to Powerscreen heavy-duty mobile screens, is designed to ensure that the 4.8m x 1.5m (16ft x 5ft) screenbox is highly effective and efficient while maintaining exceptional throughput productivity.
With amplitudes and accelerations in excess of 16mm and 6G, respectively, the Warrior 2100 triple-shaft screen is said to be more prolific at removing and breaking up clay materials than any of its class rivals, especially in sticky scalping applications.
With media solutions that include Bofor grizzly, finger modules, punch plate and new 3D punch plate, Powerscreen say the adjustable speed, stroke and timing parameters of the screen, give the Warrior 2100 an unrivalled level of versatility and performance across a broad spectrum of applications, from recycling and biomass to more mainstream tasks including aggregates and overburden.
Generous stockpiling capacity is standard on all conveyors with the chassis riser and the telescopic side conveyor option offering further significant benefits. Moreover, the Warrior 2100 screen is equipped with a long tail conveyor that allows the feeding of a secondary plant without benching in almost all instances.
Serviceability features include a class-leading screenbox ‘raise’ function and the ability to raise the collection conveyor, whilst optimal chute design in conjunction with the feeder under-tray slide-out function minimizes potential spillages and reduces any harmful material build-up around the machine.
The Warrior 2100 has been designed with economy in mind, with reduced fuel consumption being offered through a lower engine running speed and enhanced hydraulics. The machine can be fitted with either a Tier 3/Stage IIIA Cat C4.4 ATAAC four-cylinder engine that develops 90kW (120hp) at 1,800 rev/min, or a Tier 4i/Stage IIIB Cat C4.4 four-cylinder engine that develops 98kW (131hp) at 1,800 rev/min.
