PULP & PAPER


GOING VERTICAL IN DEWATERING VERTICAL SCREW THICKENER


Taking it vertical — often, the simplest ideas are the best. The pioneering Vertical Screw Thickener (VST) is a screw press with a vertical design, which enables pulp thickening from low (3%) to high (>30%) consistency within one innovative unit. The self- fi lling and gravity-assisted dewatering principle scores important points:


• Higher throughput and plup dryness because the available screen area is fully used


• Even dewatering from top to bottom, thus eliminating fluctuations being passed on to subsequent equipment


• Perfect for retrofit installations thanks to its very small footprint


Thus, the Vertical Screw Thickener offers significantly higher dewatering efficiency* and can be applied in processing all types of pulp.


* Compared to a conventional screw press in the same application
