SANDVIK QA451 MOBILE SCREEN

QA451Sandvik

Mobile triple deck Doublescreen... in Action

ULTIMATE SCREENING SOLUTION
The QA451 is the largest and most impressive mobile tracked screener in the Premium range and the only screener in the world with a triple decked Doublescreen screening system. Building upon the success of the QA450, the QA451 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 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.
