Sandvik Construction launches new QA441 Doublescreen

Published by
World Cement,

Sandvik Construction has launched the new QA441 Doublescreen, which has been upgraded to encompass the many product refinements of the larger QA451 triple deck version in order to improve operation, efficiency and ease of maintenance.

New features on the QA441 include a colour-coded push button control system with sequential start-up for ease of operation, as well as an updated feeder hopper and feeder drive system for increased throughput. To speed up screen media changes, the QA441 includes hydraulic screen separation, new wrap around walkways, a newly designed access ladder, optimised screen drives and a hydraulic raise/lower facility on the main conveyor. The standard radio remote control and upgraded electrical system will also further enhance operator safety and control.

Featuring the patented Doublescreen system, this unique, technology is a revolutionary design utilising two high velocity screen boxes that work independently of each other; the primary screen works as a fines extractor, whilst the secondary screen operates as a grader. Advantages of the Doublescreen include greater material control, greater adjustability, increased accuracy and higher screening efficiencies, making it ideally suited for producing massive volumes of high specification products, without compromising on productivity.

The QA441 is therefore suitable for large scale aggregates producers, but lends itself to many applications including iron ore, topsoil, recycling, minerals, coal, sand and gravel.
