Abstract
1297425 Pulp screening machine BIRD MACHINE CO 19 May 1970 [2 June 1969] 24142/70 Heading BID An otherwise conventional paper pulpscreening machine has a screen comprising groups of slots, and the slots near the inlet 16 extend at an angle to those near the rejects outlet 30, so that despite the variation in direction of flow of suspension across the screen from inlet to outlet the suspension crosses all the slots in a direction approximately transverse to their length. The screen is cylindrical and suspension from inlet 16 passes over baffle 20 into an annular space between the screen and rotary drum 36 whose surface irregularities clean the screen. Fig. 1 shows only two groups of slots, but there may be intermediate groups, oriented at intermediate angles.
