Paper Machine Roller with Suction Vacuum Press Roll and Vacuum Touch Rolls and Suction Press Rolls Description

Paper Machine Roller with Suction Vacuum Press Roll and Vacuum Touch Rolls and Suction Press Rolls is mostly used in medium and high speed paper machines. The upper roller of vacuum press is stone roller, and the lower roller is vacuum roller. The structure of the vacuum roller is basically the same as that of the vacuum couch roll. The roll shell is made of bronze or stainless steel, and the thickness of the shell is determined by the required stiffness and strength. Other working parameters of the paper machine, such as speed and vacuum degree, remain unchanged. The thicker the roll shell is, the smaller the dewatering capacity is. In high-speed papermaking, the moisture in the blanket and wet paper is sucked out, passes through the eyelet on the roller, and then turns around the vacuum suction area before being thrown into the white water pan by the centrifugal force of the roller. The function of the vacuum chamber is only used to suck the air in the hole of the shell. The thicker the roller shell is, the more the volume of air is pumped. Therefore, the vacuum roller with thin shell made of high-strength metal is beneficial to improve the press dehydration efficiency.
