1.Working principle of suction couch rollerThe working principle of suction rollers is mainly based on the principles of vacuum adsorption and pressure difference. When the pulp passes through the vacuum roller, the vacuum chamber inside the roller forms negative pressure, attracting the moisture in the pulp. After being adsorbed onto the surface of the roller shaft, the moisture content of the paper significantly decreases through subsequent pressing and drying processes.
