Suitable to work both with virgin pulp, recycled paper and paper machine or converting broke in the stock preparation, the TT Pulper is designed to perform an extremely efficient and low energy slushing. The configuration of the vat and the shape of the rotor optimize the pulping effect on fibers at 5 to 9% consistency, assuring an extraordinarily good fiber circulation within the vat which can be therefore reduced in volume. The rotor, that is vertically adjustable, is manufactured in a special stainless steel highly resistant to abrasion and corrosion and has bottom foils to keep the filtering plate clean.The shaft sealing can be provided with stuffing box and mechanical seal.
The TT Pulper is operated either in batch or on a continuous mode and can be equipped with a secondary pulper (TT VortiScreen-VS1 and/or TT RotatingScreen) in case of recycled paper usage.
Accessories, such as the heavy reject trap and the discharge door, can be fit on the unit depending on the application. In addition, for the larger sizes of the TT Pulper, the drive system includes an orthogonal gearbox rather than the traditional V-belts and pulleys. In all its configurations, the TT Pulper features reliability and ease of maintenance. Existing pulpers can be upgraded by retrofitting the pulper rotor to meet increased process requirements.
