40-70mm Steel Suction Pressure Drilling Paper Machine Roll

40~70mm steel sutcion Pressure drilling Roll

40~70mm steel sutcion Pressure drilling Roll Introduce

Suction rolls are located in different positions of a paper machine: Suction Forming Rolls, Couch Rolls, Pick-Up rolls, Suction Press Rolls with shell in stainless steel or bronze, with a silent drilling pattern to less the noise. The internal suction box in stainless steel has air-loaded seals made of anti-wear graphite-based material and moreover internal showers with re-circulation are provided. Both the suction angle and width are adjustable during the production.
The vacuum box can be divided in different zones, for different levels. The connection with the vacuum system is provided on the front side or on the drive side if the roll is not directly driven, thus avoiding the installation of the internal bearing, useful solution for smooth operations and an easy maintenance.
