The main feature of the vacuum transfer roll is that there are many through holes with smaller diameters on the roll shell. The through holes pass through the lining layer and the body layer, and the inner cavity of the roll shell maintains a continuous vacuum during operation. The function of the vacuum degree of the inner cavity of the vacuum press roll is to force the water squeezed out of the nip to pass through the felt, through the through holes on the vacuum roll, and enter the inner cavity of the roll shell. This process takes a certain amount of time. The higher the vacuum degree of the vacuum roller vacuum area, the shorter the time. In the same time, more water will be sucked out, and the paper will be dehydrated more, that is, the dehydration capacity of the vacuum roller the stronger.
