Abstract (en)
[origin: EP0616072A1] In the screening process for fibrous suspensions a partition (3, 3') with openings is used, through which the components of the suspension (S) to be screened are classified according to size. In this case, on the supply side (4) to the partition (3,3'), the gentle removal of the rejected components is achieved with the aid of flow vanes (7,7'), while on the passage side (5), pressure surges are generated by means of reamers (6), pass through the openings of the partition and prevent their blockage. <IMAGE>
