Designed for the aggregates producer that requires large throughput, true mobility and clean gradings, Sandvik’s QA450 screening configuration consists of two individual 10- x 5-ft. screen boxes incorporating three decks in each screen box, allowing for a more concentrated screen. Each screen box possesses its own separate drive, and is angled to aid the screening process. The screen box arrangement presents a massive screening area, yet allows for an incredibly clean product through the independent set up of the two screen boxes. An extra side conveyor enables the QA450 to produce up to a total of five product materials. Longer, chevron belted side conveyors feed directly into a cone crusher, and/or offer stockpiling capacities.
