Sandvik QA451

Mobile doublescreen

Building upon the highly advanced features of the QA440 and original QA450, the QA451 represents the second generation product with numerous product refinements, whilst retaining the triple deck screen box that enables it to produce up to four different product types plus one oversize.


Designed with maximum productivity, the QA451 incorporates a large feed hopper, two large screen boxes and extended conveyors that afford massive stockpiling capabilities.


The QA451 screenbox makes use of the tried and tested Doublescreen technology but with a unique triple deck design.
