Abstract
A decanter centrifuge is disclosed for separating a liquid feed mixture into constituent parts. The decanter centrifuge includes a bowl assembly mounted for rotation about a longitudinal axis. Opposite ends of the bowl assembly are rotatably supported by first and second bearings. A motor is engaged with one end of the bowl assembly for rotating the bowl about the longitudinal axis. A screw conveyor is coaxially mounted within the bowl with a conveyor shaft attached thereto. A gear box is located between the second bearing and the bowl and includes a transmission engaged to the shaft. The transmission rotates the conveyor at a relative speed with respect to the bowl. A plurality of circumferentially spaced posts mount the gear box to the bowl, spacing the gear box apart from the bowl. Effluent discharge ports on the bowl discharge effluent into the space between the bowl and the gear box.
