included a new bale pulper with an innovative new rotor design, two OptiFiner deflakers, an OptiFiner Pro refiner and an under machine pulper.
Co-operation is the key After the start-up, the Essity crew and Valmet worked closely to tune up the system. The target is to use more wet strength, and the percentage of recycled paper used has increased from 20 to 60 per cent. According to Bellucci, the supplier’s support in problem solving is important. “We’ve met with trust and openness. Valmet has been open to our suggestions too, and we’ve worked together very well, despite some challenges,” adds PM operations manager Matteo Vanuzzo.
Innovative pulper rotor increases efficiency Essity’s bale pulper is equipped with completely new rotor geometry, which dampens the impact of bales, reducing the load on the shaft, bearing, motor and drives, and creating a much stronger pumping effect for improved disintegration efficiency and a shorter retention time. This in turn reduces energy consumption and increases pulping capacity. “The new bale pulper is
working out very well for both the operation and the operators. We can now repulp every kind of wet strength broke without any problem at the engine’s maximum speed,” says Vanuzzo. “We can also run the rotor energy efficiently, without
jeopardising the correct mixing of dyes. We’ve been able to halve the discharging time, and the working environment is safer for the operators,” he continues. “The mill is also happy with the energy-efficient deflakers and refiners. The system is working well, and we’re enjoying producing the right quality for our customers with increased profitability,” confirms Bellucci. “I think we have the greatest team I’ve ever been part of at this mill. We can do everything with this team – hit the customer’s quality targets and keep aiming higher,” says Vanuzzo. More information from
