TEREX Pegson crushers on static display include the well-established and successful Metrotrak HA, XR400, 1000SR and 1412 Trakpactor mobile plants. In the demonstration area, TEREX Pegson is working an XA400 feeding a 1300 Maxtrak paired with a Powerscreen Horizon 6203R screening plant which, in turn, is feeding the new XV350, which recirculates oversize back into the Horizon 6203R. This new Powerscreen plant is three-way splitting and stockpiling end-product sizes of -5 +0mm, -20 +5mm, -20 +10mm. Also on demonstration is a second 1412 Trakpactor equipped with an underpan feeder specifically designed for recycling applications and which can achieve a throughput in excess of 500 tonnes per hour.

TEREX Pegson and Powerscreen International's impressive two-storey joint hospitality suite features displays and information areas on all aspects of crushing and screening applications with Pegson and Powerscreen plants, together with sales engineers and product support personnel from both companies on hand at all times. This co-operative venture is a reflection of the strengthening and aligning of their worldwide distributor network and is indicative of the synergy that exists between the two companies and their compatible product ranges.

World Premiere - The New XV350
This latest development from the engineers at TEREX Pegson features the well-proven TEREX Canica 2050 DG vertical shaft impactor. This is driven from the 438HP Caterpillar C13 engine via a self adjusting HFO clutch with a wedge belt drive through a countershaft assembly. The VSI is fitted with a shoe and anvil arrangement, which is interchangeable with a variety of other configurations depending on the requirements of the application.

The XV350 is fed by a 1.3m wide variable speed incline feed belt which can be hydraulically raised and lowered for transport purposes. This new plant accepts a maximum feed size of up to 102mm, producing a maximum throughput of up to 350 tonnes per hour - depending on the application. The throughput material from the VSI is fed onto a 1m wide product conveyor which has a 3.46m discharge height. The XV350 is controlled by a state-of-the-art touch screen control panel.

For true site mobility, this new plant comes equipped with a heavy-duty crawler undercarriage on the well proven Terex Pegson "I" beam chassis. 500mm wide heavy-duty trackpads ensure excellent traction with optimum operational stability. An umbilical control is used for tracking speed and direction.

Standard specifications include spray bars with atomizer nozzles for dust suppression at the crusher mouth, product conveyor feed and discharge end.

The Metrotrak HA
The Metrotrak HA mobile jaw crushing plant features Pegson's own development in CSS hydraulic adjustment of the "M" Series single toggle jaw. This uses two tapered cross beams, obviating the need for shims and drawback rod for adjustment (40mm to 100mm); feed opening is 900mm X 600mm. Caterpillar powered and equipped with a high efficiency HFO self-adjusting clutch with electro-hydraulic operation, the Metrotrak HA is capable of an ouput of up to 175 tonnes per hour, depending on setting and material feed.

The large hydraulically folding feed hopper has a 3.6m³ capacity and is constructed from reinforced Hardox wear-resistant plate. The 800mm X 3800mm vibrating grizzly feeder has a heavy-duty mechanical vibrating unit with twin cast eccentric shafts. Finger bars and underscreen allows grizzly fines to be directed on to the main product or optional side conveyor by fitting a blanking mat or wire meshes with a choice of apertures. Variable speed control allows smooth and continuous materials feed.  The integral product conveyor is 800mm wide and the discharge height is 2.9 metres. The heavy-duty crawler track undercarriage, fully skirted conveyor and remote control ensure that the plant can be set up very quickly and easily moved on site.

Dust suppression sprays are fitted as standard and among the optional extras available are:- Side/dirt conveyor; radio remote control; magnetic overband separator.

The X400 Series
The X400 series is on show in both hydraulic adjust (XA400) and hydraulic release (XR400) versions. Designed and built for primary crushing, these versatile crushers are equally productive and include features that are ideal for both quarrying and recycling applications.

The XA400 has a highly aggressive crushing action with hydraulic crusher setting adjustment. The high-swing jaw eases material entry into the crushing chamber and the hydraulic adjustment has been developed to enable crusher setting changes to be made quickly and easily over a wide range.  The adjustment is activated without the need to release the draw-back mechanism and this system is particularly suitable for applications where regular jaw setting adjustments are required.

The XR400 with hydraulic release has been specifically designed to alleviate problems associated with crusher overload which can be encountered when tramp metal enters the crushing process - particularly prevalent in the recycling of C&D waste. The hydraulic release is fully adjustable, quick and easy to reset and makes blockage clearance a simple process. This saves time and money by allowing the crusher to continue processing with minimal disruption to the task while, at the same time, protecting the jaw mechanism from potential damage.

There are numerous innovative features on the X400 series to improve productivity and enhance maintenance procedures. For example, the feed hopper is constructed from 15mm heavy-duty Hardox for prolonged active life and is hydraulically folding with boltless fixing; there is a newly designed and improved crusher drive access system; an easy access power pack canopy; hydraulic and oil filter changes are only required at 2000 hours intervals; there is also excellent under crusher accessibility for the safe and easy removal of wire with a hydraulic titling conveyor system. The strong I-beam construction of the chassis is designed and built to withstand even the most arduous of conditions and the low ground pressure crawler tracks are site proven for the toughest of terrains.

Driven by a Caterpillar 172kW C9 engine, the new X400 series is PLC controlled for optimum performance with finger-tip actuation and simple, automatic start sequence.  The highly efficient HFO direct drive system engineered into the plant gives remarkably low fuel consumption figures - as little as 22 litres per hour, depending on the application. A new style of vibrating grizzly feeder, with an extended twin cartridge grizzly section, actively discourages pegging and blinding. An improved impact area under the product conveyor, at the crushing discharge point, has been introduced and the hydraulically elevating and lowering product conveyor itself has an increased discharged height for even better stockpiling. For transport, the conveyor can be quickly lowered to reduce the overall height of the plant.

The numerous options on the X400 series include dirt conveyor with a new troughing system, overband magnet, radio remote control and under feeder screen. For additional belt protection on recycling applications, TEREX Pegson can also offer an optional under crusher flipper plate.

The 1000SR Combined Crushing & Screening Plant
The 1000SR mobile plant combines the high performance of the popular tracked 1000 Maxtrak with a double deck sizing screen and a re-circulating system all on one single tracked chassis. This enables customers to take advantage of the well-known and site-proven benefits of the Automax cone crusher, which is now incorporated into a closed circuit screening plant, thereby eliminating the need for separate screening. This versatile, mobile combination plant is ideally suited for secondary and tertiary applications in quarrying, where high quality, low flake, single size aggregate and "all in" sub-base materials are required.

The 1000SR accepts an "all-in" clean feed and produces high throughput, excellent reduction and product shape whilst also allowing operators to recirculate oversize from the screen, or to stockpile it if required. In addition the plant is also able to produce two further screened product sizes when the optional additional stockpiling conveyor is included. The fines conveyor incorporates a simple and effective system providing access for mesh changes, screen and conveyor maintenance.

The generously proportioned hopper has a convenient feed height of 2.8m, with a 1m wide variable speed feed conveyor carrying the material to the cone crusher - feed size options are between 63mm and 195mm and a metal detector is fitted on the feed belt. Oversize material is recirculated via the 500mm wide closed circuit conveyor. The two-deck sizing screen has an area of 1525mm x 3350mm and the underscreen stockpiling conveyor is 1400mm wide with a stockpiling height of 2.93m. Power is provided by a 258kW CAT engine, with a fuel miserly direct drive configuration and the plant also features state-of-the-art CANBUS PLC controls. The new 1000SR can achieve capacities of up to 225 tonnes per hour and is capable of stockpiling 1, 2 or 3 product sizes.

Optional extras include bottom deck stockpiler, screen bottom deck meshes, side conveyors and remote control.

The 1412 Trakpactor
This track-mounted primary impactor from TEREX Pegson is simple to operate, easy to maintain and uncomplicated in design. Versatile enough to be equally at home in quarries or on recycling duties, the 1412 Trakpactor is highly fuel efficient, capable of huge reduction ratios and has an output capacity of up to 550 tonnes per hour. The model on demonstration is equipped with an under pan feeder designed for use on recycling applications.

The 1412 Trakpactor is equipped with a Hazemag AP-PH 1214/Q impactor with four reversible and replaceable fixed blowbars. This plant offers impressive reduction ratios producing, for example, up to 85% passing -32mm on primary limestone applications in one pass.

A particular feature of this crushing plant is the hydraulic apron locking facility, including hydraulic overload protection. This eliminates apron bounce, maximises the reduction, provides consistent product size with less oversize than conventional spring loaded impact crushers, as well as an additional protection against tramp metal - particularly important on recycling applications. The crusher opens and adjusts hydraulically and a hydraulic tilting feed plate is also fitted to improve blockage clearance. The 1412 Trakpactor incorporates the latest high-technology PLC control system which can also be used to automatically regulate the feed to the crusher based on engine load.

The 1300 Maxtrak
The 1300 Maxtrak is based around the company's famous Automax cone crusher featuring a high performance 1300mm cone and available with a choice of liners suitable for secondary, or tertiary applications.

The Cat powered 1300 Maxtrak can be used for making aggregates, surface dressings, road-base or rail ballast, with capacities up to 360 tonnes per hour depending on the

material feed sizes and products required. The 1300 Maxtrak can also be used as a primary crusher, where the feed material is of a size to readily enter the crushing chamber - for example on gravel crushing applications.

A unique system, with feed hopper and level probes, ensures continuous choke feeding of the cone crusher, improving cubical shape and increasing fines production for 'road-base' use. In most applications, this unique system is able to take an "all-in" feed from the jaw crusher, thereby eliminating the need for pre-screening which would reduce the cubicity of the finished product. The generously proportioned feed hopper can accept material from a loading shovel, excavator or conveyor.

The taper roller bearing design of the Automax, with hydraulic setting, tramp release and unblocking system ensures excellent productivity and ease of operation. Adjustment can be made "on the run", using the touch button controls with direct read-out of the closed side setting. The 1300 Maxtrak is equipped as standard with dust suppression spays and a metal detection system to reduce the chance of tramp metal entering the crushing chamber.
