The machine, receiving its global launch at Hillhead 2010, boasts 40% more screening area than its predecessor, the QE340, and its stockpiling conveyors are both wider and higher to deal with the increased production capacity and facilitate larger stockpiles.
Punched plate, heavy duty mesh, rock fingers or grizzly bars can be fitted to the top deck while heavy duty mesh or fingers can be fitted to the bottom to match specific application and material requirements.
The QE440, fully tracked for on site mobility, comes complete with a more powerful, yet economical engine to power the machine whose applications include the screening of heavy overburden at a quarry face; pre-screening and scalping; recycling of construction and landfill waste, and separation of cohesive aggregates.
"The QE440 has a total scalping area of 5.5m x 1.75m/5m x 1.75m) and is capable of being fed by large crushers, yet precise enough to produce accurate aggregates, and tough enough to recycle mixed materials," says Sandvik.
With a heavy-duty crusher-type chassis, the machine can operate in the most hostile environments; has massive stockpiling capability through integrated hydraulic conveyors, and is easily transported from site to site.
