Large quarry operators and aggregates producers of virgin and recycled materials can now benefit from Extec’s Doublescreen design technology, following the introduction of the new S-7 track-mounted mobile screen. The unit is the largest model yet in the company’s S-series of screens and is designed to provide high levels of productivity, mobility and versatility. And, most significantly, it is capable of producing four products via the triple deck construction.
The machine features the same Double-screen design as the smaller S-4, S-5 and S-6 but boasts a triple-deck configuration together with an additional side conveyor. Together with a large feed hopper with optional double-deck vibrating grid and a set of extended conveyors, these features make the Extec S-7 the most productive mobile screen in its class, the company states. With a transport weight of 85,142 pounds (38.2 tonnes), the Extec S-7 is powered by a Deutz BF4M 2012 diesel engine developing 100.4 hp (74.9 kW) that meets or exceeds all known emissions regulations.
The Extec S-6, which is 59 feet, nine inches (18.0 metres) in length, utilizes two independently-adjustable screen boxes that each measure 10 by five feet (3,048 x 1,524 mm) to produce an exceptionally large screening area for optimum efficiency. Like the S-6 model, the Extec S-7 is carried on a large, durable chassis that provides enhanced strength and rigidity. A self-loading hydraulic bogie provides independent transport capability.
