Improved Extec Jaw Makes SAIE Debut

Friday, September 21st, 2007

Extec Screens and Crushers Ltd will use the SAIE exhibition in Bologna, Italy (24 to 28 October 2007) to highlight its position at the forefront of crushing and screening equipment design. It’s display will showcase the company’s popular S-4 screen and the C-10+ track-mounted jaw crusher that is making its SAIE debut.
Visitors to the SAIE exhibition in Italy (24 to 28 October 2008) will have the opportunity to view the latest equipment developments from world-leading crushing and screening equipment manufacturer, Extec Screens and Crushers Limited. The company, now part of Sandvik Mining and Construction, returns to the Bologna showground with a display that includes the recently upgraded C10+ jaw crusher which is making its SAIE debut.
Low-Maintenance Design
The new C-10+ builds upon the reputation of the larger Extec C-12+, the best-selling track-mounted jaw crusher in the world, and is designed specifically for applications in small quarries, demolition sites, and recycling facilities. With a working length of under 12.5 metres and an operating weight of 32.1 tonnes, the C-10+ is powered by a 160 kW Caterpillar C6.6 diesel engine that meets all known emissions regulations and which offers excellent fuel economy. A vibrating feeder ensures a consistent flow of material to the unit’s 1,000 x 650 mm fully-adjustable and hydraulically-controlled jaw crusher.
The C-10+ is designed for optimum uptime coupled with the lowest possible levels of maintenance. The jaw action can be quickly and easily reversed to free blockages while a “fast track” facility helps clear the machine of tangled steel reinforcing bar, a common cause of crusher downtime in recycling applications. The entire machine can also be raised hydraulically to facilitate cleaning and routine maintenance duties. In addition, the Extec C-10+ is supplied with SKF sealed for life bearings and an automatic jaw lubrication system as standard.
Doublescreen Performance
Joining the C-10+ on the Extec Screens and Crushers stand is the S-4 screen, a new track-mounted mobile screen that is designed for a multitude of quarrying, mining and recycling applications and which provides optimum performance in a variety of materials including sand, gravel, coal, limestone, granite and construction and demolition waste.
Weighing 28.0 tonnes, the S-4 is the smaller brother to the world leading Extec S-5 and shares many of the features and benefits of its larger sibling. The Extec S-4 is powered by a Deutz BF4M 2012 diesel engine developing 74.9 kW that meets or exceeds all known emissions regulations and which boasts a fuel consumption of just 19.3 litres/hour under 100% engine load.
Despite its compact dimensions – 15.8 metres long by 16.8 metres wide in working configuration with the conveyors extended – the Extec S-4 utilises two independently-adjustable screen boxes to produce a screening area that is equivalent to a traditional 4.8 x 1.5 metre screening system.
Driven and angled separately, this unique Extec Doublescreen system allows the first screen box to be used to remove fines in even the most cohesive materials, while the second screen box acts as a materials grader. As a result, the Doublescreen system is able to produce consistently precise material grades.
To supplement the productivity and versatility of the Extec S-4, the unit is offered with a variety of optional extras including a remote control system, shredder box for green waste applications, and a vibrating grid.
Extec Screens and Crushers Ltd will be appearing on Stand D91-E90 in Area 48 of SAIE’s Bologna showground.
