Paper Making Suction Couch Roll for Paper Mill
The structure of the suction couch roll is similar to that of the vacuum roll, but there are several differences. The vacuum chamber width of the vacuum press roll is narrower, usually 100mm. The diameter of the small hole in the surface of the vacuum press roll is about 4.5mm. The opening rate of the roll surface is low, which is generally 15-25%. The surface of the vacuum press roller roller surface needs to be wrapped, and the thickness of the film is 20mm.
The pressure of suction couch roll is different according to the moisture content of wet paper, the quantity and type of paper, and the strength of roll shell. Generally, the vacuum degree of the vacuum press roller of 20-50KN/m. medium speed paper machine is generally 39.2-49Kpa, and the high-speed paper machine can reach 58.6-63.6Kpa.
Suction couch roll can remove more water from wet paper, increase the sensitivity of paper and compare with ordinary roller, and the paper is less crushed. The dehydration is uniform along the width of the width, and the blanket is more stable.
Material:The shell of the suction couch roll is made by centrifugal casting of tin bronze or stainless steel material.
