Grooved press roll is a more recent innovation in trasverse-press design with higher dewatering efficiency. The grooved press roll is always applied to middle or high speed paper making machine.It can undergo higher linar pressure. The grooves in the roll cover provide easily accessible receptacles for the expelled water.The helically cut grooves are typically 0.100 inch in depth,0.020 inch wide on 0.125 inch center.The maximum lateral distance for water travel in the grooves press is therefor ,only 0.050 inches,as compared to typical figures of 0.2 and 0.75 inch respectively for the suction press and plain press.Since the grooved roll is solid,higher pressure can be appied . The water caught in the groove is thrown off by centrifugal force and the roll is cleaned by suction of sprays and doctor. We can supply all kinds of grooved press rolls according to your requirements in your paper mill with best service.
