Sandvik QE442 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 18’ x 6’ / 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.
