Once again, TEREX Pegson is taking the valuable opportunity of exhibiting at Bauma 2007 - the international showcase for the construction, mining, quarrying, recycling and materials handling industries. TEREX Pegson has always recognised the importance of their export markets and has developed a network of over 100 appointed dealers, which are internationally recognised for delivering the highest possible standards of sales service and product support. In addition to the company's own experienced sales engineers and technical staff on the stand, regional distributors Christophel GmbH and Kolsch Baumaschinen GmbH (who also represent Powerscreen International) will be manning the crushing and screening display area to offer sales advice on products being exhibited at the show.

Forming an integral part of the impressive TEREX Group Stand (704/705 - F7) TEREX Pegson is exhibiting three of the company's most successful crushing plants.
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.

Users of the best-selling 1000 Maxtrak will have already experienced the ability of this plant to accept an "all-in" clean feed and to produce high throughput, excellent reduction and product shape. The new 1000SR retains these advantages but also allows customers 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 screen section incorporates a simple and effective system providing access for mesh changes, screen and fines conveyor maintenance.

The generously proportioned hopper has a convenient feed height of 2.8m, with a 1000mm wide variable speed feed conveyor carrying the material to the cone crusher - maximum feed size varies between 63mm and 195mm depending on crusher configuration 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 is a 1525 x 3350mm and the underscreen stockpiling conveyor is 1400mm in width, having a stockpiling height of 2.93m. Power is provided by a 258kW CAT C9 engine, with a highly fuel efficient direct drive configuration. The plant also features state-of-the-art CANBUS PLC controls. The new 1000SR can achieve capacities of up to 180 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 conveyor 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 packed with customer benefits, is highly fuel efficient, capable of huge reduction ratios and has an output capacity of up to 450 tonnes per hour. The model on show is equipped with an under pan feeder and is being displayed feeding a mobile screening plant - the brand new Horizon 5163 being launched at Bauma by fellow Terex Group company Powerscreen International - clearly demonstrating the compatibility of both Pegson and Powerscreen plants, which frequently work in tandem to produce high specification end products and excellent throughput capacities.

The 1412 Trakpactor is equipped with a Hazemag AP-PH 1214/Q impactor with four reversible and replaceable fixed blowbars. This new plant offers impressive reduction ratios, producing up to 85% passing -32mm on primary limestone applications in one pass. Designed with a 1200mm wide product belt, it has 3.92m discharge height and is able to raises/lower hydraulically, giving a massive under chassis clearance for the removal of rebar.

A particular feature of this crushing plant is the hydraulic apron control system incorporating 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. A hydraulic tilting feed plate is also fitted to improve blockage clearance. The 1412 Trakpactor incorporates the latest high-technology PLC control system, with minimal wiring, and this can be used to automatically regulate the feed to the crusher based upon engine load.

The X400 Series - Show Debut
The X400 primary crusher series was launched by TEREX Pegson in early spring last year and, making its first public appearance at an exhibition, is already well established as a highly productive, economical and versatile range of mobile crushing plants, equally at home in the quarry or on recycling applications. This plant has been designed to provide unsurpassed reliability, is simple to operate and has excellent under engine access for easy maintenance with a hydraulically tilting product conveyor. There are two versions available to suit customers' requirements. The XR400 with hydraulic release and the XA400 with hydraulic adjustment and tonnage rate up to 350 tph.

The X400 series has a highly aggressive crushing action and the high-swing jaw facilitates easy material entry into the crushing chamber. The hydraulic adjustment (XA400) enables 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 frequent 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. The crusher will self-protect and open in the event of an overload being encountered - particularly prevalent in the recycling of construction and demolition waste. The hydraulic release feature 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 track is site proven for the toughest of terrains.

Driven by a Caterpillar 172kW C9 engine, the 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. In these days of increasing fuel and hydraulic oil prices, significant annual savings in running costs are easily achievable compared with similar sized competitors' products. 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 to 3.9m for even better stockpiling. For transport, the conveyor can quickly be lowered to reduce the overall height dimension of the plant.
