The QE441 Free Flow is Sandvik Mobile Crushers and Screens’ new scalper range model.
The model is said to be a versatile and highly efficient mobile solution for handling sticky, moist and wet materials with a high percentage of fines, and to be an ideal solution for processing materials such as soils, aggregates, ores, waste, biomass and other waste-derived fuels, including products with high moisture contents.
“We have designed this unit based on the sturdy crusher-style chassis of our QE441, combined with a highly productive and aggressive double-deck Free Flow screen,” says Sandvik.
“The heavy-duty scalping screen allows you to process large un-screened material on the rigid scalping top deck, whilst providing a fine screening solution on the dual motion lower deck. The powerful snapping of the bottom deck media generates an active ‘flip-flow’ movement which generates a huge throw that propels material upwards and outwards separating material as it does so and thereby eliminates any plugging and blockages. This results in the processing of more sellable products and less waste.”
The QE441 Free Flow chassis is designed to accommodate interchangeable side conveyors and is compatible for two-way or three-way split configurations, and the modular design screen box offers easy replacement of screen media.
