Abstract

A process for the drying of pulp which process comprises the steps of, providing a pulp comprising cellulosic fibres (fibers), conducting the pulp to a wire (2), dewatering the pulp by the aid of a suction roll (1) wherein the suction roll has an open surface area of above 60% and a shell (3) thickness of above 50mm. By increasing the open surface area of the suction roll the dewatering of the pulp is increased. A suction roll for performing the process is also described.
