Abstract

The angle (alpha) of the bars (11) in the screening surface is 2-20 deg. relative to the cylinder axial direction. A cylindrical screen (10) for fibrous suspensions of lignocellulosic material comprises a number of bars held together by support rings to form gaps (12) in the cylinder length direction. The angle of the bars relative to the cylinder axial direction is 2-20 deg.
