Efficient wet strength broke pulping after stock preparation rebuild

Essity’s Collodi Mill in Italy solved their stock preparation challenges by rebuilding the existing system. TM2 produces colored tissue grades and that places high requirements on stock preparation, especially in terms of capacity, energy consumption and safety. The rebuild included a new bale pulper with an innovative rotor design well suited for wet strength broke repulping, two OptiFiner deflakers, an OptiFiner Pro refiner and an under machine pulper.
