Sandvik at the Double


SANDVIK has introduced the new QA441 Doublescreen, 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 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 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, which is celebrating its 15th anniversary this year, 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.

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