Problems are often encountered with conventional rolls when processing pulp. The rolls cause high specific pressures as well as a short nip. To prevent this, Voith is now offering a new polyurethane (PU) roll cover that has been developed for press rolls: the IntensePress. This has been specifically designed for use in the demanding applications of pulp machines and twin-wire presses.

Voith offers a new polyurethane (PU) roll cover that has been developed for press rolls: the IntensePress. This has been specifically designed for use in the demanding applications of pulp machines and twin-wire presses.

The decisive advantage of IntensePress is its high chemical resistance. Furthermore, it is characterized by a high level of temperature resistance. Both features increase the running time of the roll, simplify work processes, and thus increase the machine’s productivity. The high chemical and temperature resistance are made possible by a new type of polyurethane.

To provide customers with the best possible output when using IntensePress, Voith is investing in individually tailored advice. The roll cover’s PU surface is modified according to individual requirements, for example, to achieve a greater open surface and thus increased dewatering performance and a higher dry content. IntensePress can also ensure a wider nip and, in doing so, minimize the specific pressure. Voith determines what the optimal nip load will look like for each customer, taking into account the individual operating conditions.

Voith not only offers the new type of polyurethane for press rolls but also for suction press rolls. The PU cover IntenseFlow, for example, has the same properties as IntensePress but differs in its surface geometry, which has been adapted to suction press rolls.

IntensePress is available in the following four versions: smooth, blind-drilled, grooved, and blind-drilled and grooved. In addition to the suction holes, IntenseFlow is available with the following surface finishes: blind-drilled, grooved, and blind-drilled and grooved.
