The Extraplus is a robust extraction system designed to operate in large silos (up to 25 m in diameter) with all materials from flakes to wood chips. The device uses a central rotating turret equipped with a progressive pitch extraction screw with milling teeth, which ensures excellent processing of the entire layer of material on the silo bottom. Thanks to the hydraulic drive, the system guarantees an easy restart even after long periods of standstill, combining high efficiency, reliability, and low maintenance costs.
