Vertical screw thickener: The latest innovation in dewatering

The pioneering Vertical Screw Thickener is a screw press with a vertical configuration and a very small footprint, making it suitable for retrofit installations in existing buildings. The pulp suspension is fed into the top of the machine, and its downward transport is gravity-assisted.
