QE341 Scalper/Screen

The new QE341 represents the most advanced and complete mobile scalper yet designed. Customer feedback has been an integral element in the development of this model and the most sought-after features have been incorporated into this unit.
Our goal of minimum user intervention means that we have focused on delivering huge stockpiling capacity, with ease of stockpile removal, uninhibited material flow and ability to handle the toughest of material with an apron feeder fitted as standard.
The 16’ x 5’ / 4.7 x 1.5 m screenbox is highly aggressive with 9mm throw operating at over 1000 RPM. This ensures that even the most difficult materials can be handled effectively.
Whether it’s working before or after a primary crusher or as a stand alone unit, the QE341 is designed to deliver high production with clean separation, the exceptional on-board conveyors ensure that the delivery is in harmony with the throughput.
Applications include screening quarry overburden, blasted rock, landfill mining, C&D waste, aggregates, slag heaps, environmental clean-ups and topsoil/subsoil.
