Powerscreen open day for aggregate crushers and screens

First published in the December 2013 issue of Quarry Management as Power Play

Powerscreen put brand new machines through their paces at international Open Day event

Customers and distributors from more than 21 countries attended the 2013 Powerscreen Open Days held from 3–4 October at Arden Brickworks near Birmingham, in the UK. The successful event saw Powerscreen unveil three new machines to the UK marketplace – the Warrior 2100 screen, the Premiertrak 300 jaw crusher and the Trakpactor 320SR impact crusher, all of which were working in recycling applications, processing asphalt, concrete, brick, and mixed demolition waste.

Warrior 2100

The Warrior 2100 screen has been engineered to include the proven triple-shaft technology first developed for the Warrior 2400 model, which is now well established in markets worldwide. This technology, which is unique to Powerscreen in heavy-duty mobile screens, ensures the effectiveness and efficiency of the16ft x 5ft screenbox while maintaining high throughput productivity. According to Powerscreen, the extreme screening acceleration gives the Warrior 2100 improved capabilities over its class rivals, especially in sticky scalping applications. During the event the machine processed mixed demolition waste which included grass, soil, concrete, wood and asphalt, and was configured with a top-deck combination of 60mm fingers and 60mm punch plate, and a bottom deck of 40mm mesh.

Premiertrak 300

The Premiertrak 300 jaw crusher featured the new, optional, hydrostatic drive system, allowing it to reverse and unblock or run continuously in reverse for asphalt applications. The machine is configured to run at low engine rev/min, resulting in a high level of fuel efficiency and very low noise emissions, making it well suited to operations on urban sites. At the Open Days, the Premiertrak 300 crusher was configured with its vibrating grizzly feeder equipped with 50mm bofor bar on the top deck and 30mm mesh on the bottom. The closed-side setting (CSS) was set to 40mm while running in both asphalt and recycled concrete applications.

Other benefits of the machine include: large clearances in the bypass chute to improve material flow and reduce the chance of blockages in sticky material; a large under-crusher clearance and full tunnelling to reduce the chance of a blockage due to rebar build-up; and a conveyor that can be lowered hydraulically for ease of access and to reduce downtime should a blockage occur.

With all folding done hydraulically, rapid set-up times are possible with no need for operatives to work at height. Plant control is via an easy-to-use PLC screen system, with jaw speed and CSS quickly changed via a single button that allows the machine to be adjusted to suit the application, with no tools required.

Also in action during the Open Days was the Premiertrak X400S jaw crusher, which has been developed to incorporate a fully independent, high-amplitude, hydraulically driven pre-screen with increased drop angle on the bottom deck to improve machine throughput and overall capacity. In order to facilitate improved pre-screened material flow, the discharge opening from the under-chute has been increased from 200mm to 320mm, allowing faster movement of pre-screened material in the crushing chamber bypass. At the event, the Premiertrak 400 was fitted with pre-screen bofor bars of 60mm on the top deck and 30mm on the bottom deck. With a closed-side setting of 45mm, the machine was being used to process recycled concrete containing a high percentage of rebar.

Trakpactor 320SR

The Trakpactor 320SR is a mid-sized horizontal impact crusher that has been redesigned with a number of key enhancements to offer operators and contractors excellent reduction and high consistency of product shape for performance in quarrying and recycling applications. The plant is capable of working in the most demanding environments and offers rapid set-up time, a fuel-efficient direct-drive system and an output potential of up to 320 tonnes/h. The plant also features a recirculating conveyor which raises for transport allowing more ground clearance under the machine when moving on site and/or loading for transport. One of the most innovative features of the Trakpactor 320SR crusher is its quick-detach post-screen section, which allows the machine to be converted into a standard Trakpactor 320 unit, providing operators with the versatility required for use in a variety of different applications.

Established models

As well as the four machines taking part in the live demonstrations, a further four well-established Powerscreen machines were on static display – a Trakpactor 250 impact crusher, a 1000 Maxtrak cone crusher, a Chieftain 1700 screen and a Warrior 1400X screen. Designed especially for the recycling and demolition markets, the Trakpactor 250 has special features designed to prevent chamber overload and damage. Capable of processing a wide range of material at a high output, the plant is versatile, easy to operate and fuel efficient due to its direct-drive system.

The 1000 Maxtrak is a small-to-medium-sized cone crusher which has been designed for direct-feed applications without pre-screening when working with clean rock. At its heart is the Automax cone crusher which provides excellent reduction and product cubicity for the production of high-quality aggregate and sub-base material. Hydraulic release capabilities are designed so that any uncrushable material entering the chamber is safely discharged.

The Chieftain 1700 is a mid-sized tracked mobile screen aimed at end-users requiring high volumes of finished products in applications including topsoil, coal, crushed stone, recycling, iron ore, and sand and gravel, while the Warrior 1400X has been specifically designed for economy, with a reduced engine running speed and enhanced hydraulics offering a reduction in fuel consumption of up to 15% compared with its predecessor.

Commenting on the Open Days, Powerscreen’s international sales director, Colin Clements, said: ‘The Open Days were an outstanding success and feedback from distributors and customers has been fantastic. Economic conditions globally may be challenging, but Powerscreen are committed to enhancing the experience of all their customers, to reinforce their position as the world’s leader in mobile crushing and screening equipment for our key sectors, and to continue to innovate as we have in the past.’
