Vacuum Suction Couch Press Roll
Vacuum Suction Couch Press Roll Description
Vacuum Suction Couch Press Roll 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.
