ABSTRACT:
A screening apparatus for separating acceptable and rejectable material from a pressurized stream of fluid pulp is provided. The screening apparatus includes a housing with a chamber having a geometry conducive for deflecting air and light materials radially away from an axis of rotation and to peripheral regions of the housing. The chamber is disposed at one end of the housing and has a dimension defined by an axial spacing between the housing and an end portion of a screen basket, the axial spacing along the axis of rotation increasing with increasing radius relative to the axis of rotation. Deflecting the air and light material away from the axis of rotation improves the separation of acceptable and rejectable materials from the fluid pulp and reduces wear of the internal components of the screening apparatus.
