The Sandvik QA451 mobile screen is the largest and most impressive mobile tracked screener in the Sandvik Premium range; and the only screener in the world with a triple-decked doublescreen screening system.
The world’s first triple-deck Doublescreen, the QA451 is capable of producing large volumes of high specification product. Featuring two in-line 3 x 1.5 m / 1 O’ x 5′ screen boxes these provide you with ultimate flexibility and control. The first screen performs as a fines extractor, whilst the second screen performs as a grader. Two processes combined on one plant. offering exceptional flexibility and massive throughput.
Building upon the success of the QA450, the QA451 mobile screen represents the next-generation model with numerous product enhancements to produce a more user-friendly, efficient, and productive unit. The QA451 is designed specifically to work in a closed circuit with our tracked secondary and tertiary crushers. The hydraulically folding fourth product conveyor slews and raises/lowers hydraulically to optimise the feeding position to these upstream units. Alternatively, the QA451 can work as an extra-large stand-alone screening and stockpiling system producing four sized products with a fifth oversize material scalped off at the grid. Designed with maximum productivity, the QA451 incorporates a large feed hopper, two large screenboxes, and extended conveyors that afford massive stockpiling capabilities. This heavy-duty machine also offers exceptional ease of use through the PLC control panel which features simple sequential start-up and a user-friendly interface.
