Powerscreen to launch new machines at ConExpo

Powerscreen Trakpactor 320SR impact crusher

Latest crushing and screening machines to make their debut at North American equipment show

POWERSCREEN have confirmed the three new exhibits they will showing at the forthcoming ConExpo-Con/Agg 2014 show, to be held from 4–8 March 2014 at the Las Vegas Convention Centre.

The latest machines on display – a Premiertrak 300 jaw crusher, Trakpactor 320SR impact crusher and Warrior 2100 screen – will showcase the company’s new, updated paint scheme that maintains the traditional Powerscreen green colour while adopting a dark grey colour on the chassis and conveyors.

The Premiertrak 300 jaw crusher features a new hydrostatic drive system option allowing the machine to reverse and unblock or run continuously in reverse for asphalt applications. It is also designed to run at low engine rev/min, resulting in improved fuel efficiency and reduced noise emissions.

The Premiertrak 300 includes a vibrating grizzly feeder set with 50mm bofor bars on the top deck and 30mm mesh on the bottom. The closed-side setting (CSS) can be set to 40mm while running in both asphalt and recycled concrete applications.

Other benefits 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 tunneling to reduce the chance of blockage due to rebar build-up; and a hydraulically lowering conveyor that offers good access to reduce downtime should a blockage occur.

The Trakpactor 320SR (pictured) is a mid-sized horizontal impact crusher that has been redesigned with a number of key enhancements to ensure 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 benefits from rapid set-up time, a fuel-efficient direct-drive system and an output potential of up to 320 tonnes/h. The 320R unit also has a recirculating conveyor, which raises for transport allowing more ground clearance under the machine when moving on site and loading for transport.

One of the key features of the Trakpactor 320SR crusher is a quick detach post-screen section that converts it into a standard Trakpactor 320 unit. This provides operators with greater versatility in a variety of different applications.

The Warrior 2100 screen has been engineered to include Powerscreen’s Triple Shaft technology, which was first developed for the successful Warrior 2400 – a model that is now well established in markets worldwide.

The Triple Shaft technology, unique to Powerscreen heavy-duty mobile screens, ensure that 16ft x 5ft screenbox is highly effective and efficient while maintaining excellent throughput productivity.

The extreme screening acceleration is said to offer the Warrior 2100 screen improved capabilities over its class rivals, especially in sticky scalping applications. The machine can process mixed demolition waste, including grass, soil, concrete, wood and asphalt, and can be configured with a combined top deck of 60mm fingers with 60mm punch plate and a bottom deck of 40mm mesh.
