Hillhead 2018: Forward Thinking Machines

Powerscreen will unveil forward-thinking machine modifications at Stand L4 at Hillhead 2018, where Powerscreen team and distributors will be available between June 26th and 28th. Exciting new offerings will be available on the Powerscreen® Premiertrak™ 600 and Powerscreen® Metrotrak™ jaw crushers, while the Powerscreen® Trakpactor™ 550SR impactor will be seen working for the very first time. The seriously impressive Powerscreen® Chieftain™ 2200 3 deck plant will be the flagship screening development at the show and features an incredibly powerful double screenbox with huge screening area.

Commenting on the forthcoming line-up, Dearbhaile Mulholland, Powerscreen Global Marketing Manager, said, “Powerscreen has developed and maintained an aggressive position in mobile crushing and screening. The industry has always looked to Powerscreen to present the future of crushing and screening. This year’s Hillhead show comes at the perfect time for us to showcase our latest developments and to continue leading the way. Located in our usual position by the quarry face, Powerscreen experts look forward to meeting visitors to present the benefits of choosing our machines and adopting our technological innovations today.”

Premiertrak 600 – XL Feeder, Maximum Strength

The Premiertrak 600 at Hillhead will be a pre-screen model featuring a never been seen before XL feeder designed for maximum strength, particularly for large quarrying applications where hard rock may be present and where large tonnages required.

The diesel-hydraulic and diesel-electric variants of the Premiertrak 600 jaw crusher have been designed and constructed to deliver maximum production and performance with increased uptime and low running costs. 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 to extend 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 machine control system incorporates a state of the art, modern interface with intuitive graphics and high resolution display for ease of operation. This is further enhanced with the automatic start/stop functionality, excellent diagnostic capability and straightforward machine adjustments.   The speed of jaw crusher on the Premiertrak 600 can be varied to suit the application and therefore optimize performance. In addition to this, the hydraulic system has been designed and configured to increase uptime and fuel efficiency.

The Premiertrak 600E electric variant is equipped with an over-size genset sufficient to run another plant (it successfully powers the large Powerscreen® Warrior™ 1400XE heavy duty scalping screen) and additionally can be powered from a mains source which substantially decreases the running costs and environmental impact.

With convenience and safety in mind, the Premiertrak 600 can be fully set up from ground level thanks to its hydraulic folding and locking hopper system. It can be adjusted to maximise productivity in any application and can be configured with an independent live pre-screen for the efficient removal of scalped materials either into a waste or a sized sub-base product.

Trakpactor 550SR – #GoBigDoMore

The new Trakpactor 550SR horizontal shaft impactor is designed for processing primary and secondary materials such as natural rock & construction derived materials like asphalt, recycling and demolition waste. The Trakpactor 550SR is proven to deliver excellent tonnage of high specification material with a low cost per tonne. It features cutting edge styling with GRP guards and also comes with the Powerscreen Pulse Intelligence system as standard giving the power to revolutionise.

The machine’s robust impact chamber (54” x 36”) features a twin apron, 4 bar rotor design, with hydraulic release aprons, hydraulic setting adjustment, hydraulic crusher overload and is driven directly off the engine via clutch for optimum fuel economy. The product conveyor features a raise/lower facility to aid clearance of rebar in the event of a blockage.

The plant has been designed with ease of maintenance in mind. Hydraulic banks, battery access and control valves are at eye level to make setup and operation much easier. The post-screen and recirculation section is fully detachable using quick release hydraulics and electrics.

Metrotrak – #ALegendReborn

In late 2017 the Powerscreen Metrotrak was reborn. Building on the global success of its predecessor, it featured important usability and serviceability upgrades. This compact jaw crusher is ideally suited for operators in the mining, quarrying and recycling industries, especially those working in tight locations where working space as well as transport space is restricted thanks to its small footprint.

The new Metrotrak has been redesigned the operator in mind with ease of use, serviceability, maintenance and material flow to the fore.  The variable speed VGF is now fitted with bolt-in stepped grizzly cassettes and rotating mesh deck which helps with quick application changes and maintenance.  The 3 way bypass conveyor is larger than its predecessor and has inspection holes and wear liners at discharge points as standard to help with material flow.  The bypass conveyor is also easy to set up, inspect and maintain and can be reversed on site if required in certain applications.

The product belt conveyor has also been upgraded.  Relocated belt tensioning bolts help keep the belt tracked, clearance under the chamber has increased and operators can now fully lower the conveyor to ground level for maintenance and service tasks while revised skirting helps eliminate snagging points improving material flow.

One of the most exciting features of the Metrotrak is the chamber unblock feature which, with the aid of a motor attached to the flywheel on the chamber, will ‘rock’ the chamber back and forth until the blockage is cleared. This gives the Metrotrak the key advantage of a hydrostatic setup whilst retaining the fuel efficiency of direct drive.

This Metrotrak is also fitted with Powerscreen Pulse which provides the owner and operator with valuable information about machine performance.
Chieftain 2200 3 Deck – “A big step up from competitors”

Launched in 2016 the Chieftain 2200 3 deck has set a new standard in high intensity screening and has exceeded expectations with customers globally. Its two highly versatile, 22’ x 5’ three deck screenboxes provide a total screening area of 19.5m2. This gives a high tonnage capacity, often exceeding 700 tph/770 US tph, resulting in increased quality product and revenue.

The machine also features a revolutionary patent pending drive system which allows switching between 2 and 4 bearing with bolt-on parts. With a 4 bearing box, the efficiency of the screen can drop as the box length increases. The box also can become susceptible to torsion, which twists the metal and can cause fatigue. By splitting up into two individual boxes, the Chieftain 2200 3 deck is able to run aggressively without the constraints of a larger box. It can screen with a 20% increase in G-force compared to other screens with the same surface area. The tumbling action between the screens helps to maximize efficiency of the screens and accuracy of the product, especially at the close size materials. The maximum variability of the machine offers improved capabilities over its class rivals, especially when trying to make high specification aggregate.
