Featuring the patented, world-class heavy duty Doublescreen screen box from Sandvik, the QA441 is the ideal solution for large-scale aggregates producers requiring large throughput and high screening accuracy. Two high velocity screens that work independently to each other, the primary screen works as a fines extractor, whilst the secondary screen operates as a grader. Two processes combined on one plant, both primary & secondary screening angles can be adjusted relative to each other. User-friendly features include an updated feeder hopper & feeder drive, an “easy to use” control system with sequential start-up. The QA441 lends itself to many applications including iron ore, aggregates, topsoil, recycling, minerals, coal, sand and gravel.Find out specs and more about the Sandvik QA441 by contacting us or visiting www.rocktechnology.sandvik.
