Building upon the highly advanced features of the existing doublescreens, the QA450 introduces a triple deck screen box, and extra side conveyor that enables it to produce up to a total of 5 product materials. Designed for maximum productivity, the QA450 incorporates a large feed hopper, a pair of large screen boxes and extended conveyors that afford massive stockpiling capabilities. The screenbox in the QA450 makes use of the tried and tested doublescreen design, but now with a unique triple deck design cementing Sandvik its position as a true world leader.
