Sandvik QA331 Mobile Screen

The Sandvik QA331 Tracked Screen is a robust, highly durable machine, designed specifically for the recycling and contractor market. QA331 incorporates a 14′ x 5′ two bearing screen box with an adjustable screening angle. The bottom deck has an extra 6 degree screening angle for ultimate screening performance. This feature, coupled with the larger screening surface area, and increased throw on the screenbox, enhances screening efficiency and capacity through the actual screenbox itself.

Features and values

  • High production rate through large screening area, high frequency double deck screen and a six degree inclined angle on screen-box to produce a “banana” effect
  • Suitable for working at the quarry face, inner city development or recycling centre
  • Modern chassis design ensures in-built machine quality and strength for maximum up-time
  • Designed for optimum fuel economy and low operating costs

Sandvik QA451 Doublescreen

The Sandvik QA451 is the world’s only triple deck Doublescreen and offers you unrivalled throughput and control. We developed this machine to provide you with massive stockpiling capabilities.

The QA451 is a formidable solution with two inline 10′ x 5′ screenboxes, a large feed hopper and extended conveyors. We have designed the QA451 to work in closed circuit with our tracked crushers. You can optimize the feeding position to upstream units as the fourth product conveyor slews and raises / lowers hydraulically. To provide ultimate flexibility the QA451 can also work as a stand-alone screening and stockpiling system. In this mode the unit can produce four sized products with fifth oversize material scalped off at the grid.

Features and Benefits:

High production capabilities due to its large screening area
Oversize conveyor which features both hydraulic raise / lower and hydraulic slew functions
User friendly control panel with sequential start-up for ease of operation.
Hydraulically folding walkways for ease of maintenance and set up
Full radio remote control as standard for safe and easy set up
Designed for optimum fuel economy to lower your operating costs

Sandvik QA441 Doublescreen

The QA441 is a highly productive 20 x 5′  double deck screen that comes equipped with Sandvik’s patented, world class, heavy duty Doublescreen system.

With two independent double deck screens you will effectively get one machine able to perform two screening processes on one plant.

Sandvik have designed this machine to suit the needs of larger operators. It incorporates a large feed hopper, two independently angled screen boxes and extended product conveyors that offer massive stockpiling capabilities. All of this is carried on a durable chassis that is designed to withstand the rigours of a bigger quarry or recycling applications.

Features and Benefits:

  • Massive production capabilities due to its substantial screening area
  • Independently adjustable screenbox angles delivering ultimate precision screening
  • Large volume hopper complete with remote control hydraulic tipping grid.
  • User friendly control panel with sequential start-up for ease of operation
  • Wrap around hydraulically folding walkways for operator safety

Sandvik QE341 Scalping Screen

The QE341 Mobile Scalper is the most advanced, heavy duty, tracked mobile scalping screen on the market.

Sandvik have designed it to handle your most difficult infeed material with a wide hopper opening, aggressive screenbox and oversize conveyor. This also ensures a free flow of material from front to back.

The QE341 Mobile Scalper features a double-plated apron feeder as standard, ensuring it can handle heavy duty scalping applications. The middle and over size conveyors can be hydraulically lowered to feed material into a cone or primary. This revolutionary mobile scalping screen is purpose built for the recycling and quarrying markets. Customer feedback was an integral element in the production of the QE341, and has resulted in a mobile scalping screen that is as user friendly as it is productive.

Applications include screening quarry overburden, blasted rock, landfill mining, C&D waste, aggregates, slag heaps, environmental clean-ups and topsoil/subsoil.

Features and Benefits:

  • Operator safety ensured with radio tracking and feeder control as standard
  • Uniquely aggressive screenbox with 9mm of throw at over 1000 rpm
  • Hydraulic folding maintenance platforms for ease of service and maintenance
  • Easy operation through a unique colour-coded control panel with one touch start/stop
  • Optimum fuel economy at less than 15 l/hour to lower your operating costs
