SOLID BOWL SCREW CENTRIFUGE HAVING COARSE MATERIAL OUTLET IN BAFFLE PLATE

摘要

The invention relates to a solid bowl screw centrifuge for separating suspensions in at least two phases and having feed devices and discharge openings for the fluid and solid phases, a rotatable drum (1) and a rotating transport screw (4) arranged coaxially in the drum (1) that circulates at a differential speed to the drum (1) and the screw tube (8) thereof having helical screw blades (5) and at least one baffle plate (16) having a gap to the drum (1). The baffle plate (16) is designed as a spiral and has at least one enlarged gap opening (25) that enables the passage of collected material through the baffle plate gap and is attached to a spandrel (22) where the baffle plate (16) meets the screw blade (5).
