Rubber Polyurethane Return Roll for Cardboard Card Paper Machine Making Mills Kraft

Product Description

Product Description
Paper Machine Vacuum Roll Vacuum suction press roll is mostly used in medium and high speed paper machines.
The function of the vacuum chamber is only to suck the air in the shell holes. The thicker the roll shell, the more air volume is sucked. Therefore, the use of high-strength metal to make a vacuum suction press roll with a thin roll shell is beneficial to improve the efficiency of press dehydration. The vacuum pressure roller shell is covered with rubber with a thickness of 30-40mm. The advantage of encapsulation is to make the pressure distribution uniform, reduce the abrasion of the felt, and increase the pressure of the press line. Production practice shows that the axial and circumferential center distance of the holes on the vacuum pressure roller is smaller, and the number of holes is larger, which can significantly improve the dehydration effect of the vacuum pressure roller, thereby effectively eliminating the embossing phenomenon and extending the service life of the felt.
