Sandvik QE441FF

Free Flow mobile scalper

Our QE441 Free Flow provides you with two screening solutions in one unit. The heavy duty scalping screen allows you to process large un-screened material on the top deck, whilst providing a fine screening solution for difficult to screen material on the bottom deck. It is your ideal solution for materials with a high fines content, such as soils, aggregates, ores, waste, biomass and other waste derived fuels including products with high moisture contents.


Featuring a highly productive 5.4 x 1.75 m Free Flow screen, this incorporates a rigid scalping top deck and a dual motion lower screen deck. The powerful snapping of the bottom deck media generates an active “flip-flow” material movement which generates a huge throw that propels material upwards and outwards separating material as it does so and thereby eliminating plugging and blockages. This mobile solution offers the user-friendly features of the 1-Series screens including an electrical control system, which improves both operational effectiveness and machine safety. The QE441 also comes equipped with 2 speed radio control tracking as standard.

  • Aggressive Free Flow screen with wide range of adjustable throws and speeds enables the bottom deck to be tailored for numerous applications
  • Easy operation through a unique colour-coded control panel with sequential start / stop
  • Operator safety ensured with 2 speed radio tracking and feeder control as standard
  • Massive stockpiling capability through integrated hydraulic conveyors
  • Compatible for 2-way or 3-way split configurations
