The Sandvik QA451 is the world’s only triple deck Doublescreen and offers you unrivalled throughput and control. We developed this machine to provide you with massive stockpiling capabilities.
The QA451 is a formidable solution with two inline 10′ x 5′ screenboxes, a large feed hopper and extended conveyors. We have designed the QA451 to work in closed circuit with our tracked crushers. You can optimize the feeding position to upstream units as the fourth product conveyor slews and raises / lowers hydraulically. To provide ultimate flexibility the QA451 can also work as a stand-alone screening and stockpiling system. In this mode the unit can produce four sized products with fifth oversize material scalped off at the grid.
