The QA441 is the largest two deck tracked mobile screen equipped with Sandvik’s world class Doublescreen system. 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 and secondary screening angles can be adjusted relative to each other, offering customers exceptional flexibility and massive throughput. Designed for quick and easy set-up, the QA441 is built to withstand the rigours of a large quarry or recycling application. It incorporates a number of features for improved safety and control, including a user-friendly electrical control system with sequential start-up for ease of operation and remote control which comes as standard.
The QA441 lends itself to many applications including iron ore, aggregates, topsoil, recycling, inerals, coal, sand and gravel.
