October 23, 2014 – Sandvik Construction announced the launch
of the new QA441 Doublescreen. This latest addition to the Premium range has
been upgraded to encompass the 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 color-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, optimized 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, the technology
is a design that utilizes 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. Doublescreen advantages over
competing products include greater material control, greater adjustability,
increased accuracy and higher screening efficiencies, making this unit ideal
for producing massive volumes of high specification products, without
compromising on productivity.

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

Features include:

•          Patented
Doublescreen featuring two independent two deck screens 6 x 1.5m (20’ x 5’)
equivalent, effectively performing two processes on one plant

•          Versatile
unit, capable of producing large volumes of high specification products

•          Large volume
hopper complete with remote control hydraulic tipping grid

•          Massive
stockpiling capability through integrated hydraulic conveyors

•          Greater
adjustability, increased accuracy and higher screening efficiencies over
competing products

•          Ease of
operation with new color-coded control panel with sequential start up

•          Ease of
maintenance with hydraulically folding walkways on three sides

•          Safety
compliant with the latest Machinery Directives and full radio remote control
throughout.
