Abstract: A centrifuge (2) for separating solids from liquid of a slurry with a conveyor (12) having a hub (14) rotatable about an axis (34) and at a helical blade (16) extending axially and radially from the hub. A bowl (4) including a cylindrical section (6) extending from an upstream end of the conveyor and a conically diverging screen section (10) extending to a downstream end of the conveyor extends about the conveyor and is rotatable about the axis. The conically diverging screen section includes an angle (40) that reduces the coefficient of friction of the solids to allow a cake formed of the solids to slide in a controlled manner forward on the conically diverging screen section with minimal back pressure, but without allowing the solid cake to break loose from the conically diverging screen section and slide out of the centrifuge in an uncontrolled manner.

Abstract: A vibrating centrifuge includes a housing; a basket rotatably supported by the housing; a main drive motor operatively connected to the basket to rotate the basket; a vibration transfer shaft operatively connected to the basket at a first end of the vibration transfer shaft to vibrate the basket; and at least one vibration motor resiliently connected to the housing and operatively connected to the vibration transfer shaft at a second end of the vibration transfer shaft. A vibration drive for a centrifuge including a basket rotatably supported in a housing includes a vibration transfer shaft operatively connected to the basket at a first end of the vibration transfer shaft; and at least one vibration motor connected to a mount, the mount being resiliently connectable to the housing, the vibration transfer shaft being connected to the mount at a second end of the vibration transfer shaft.

Abstract: A centrifuge (2) includes a conveyor (12) including a hub (14) rotatable about an axis (34) and at least one helical blade (16) extending radially from the hub and in the axial direction of the hub. A bowl (4) extends about the conveyor and is rotatable about the axis. The bowl includes a cylindrical section (6) extending from an upstream end of the conveyor and a conically diverging screen section (10) extending to a downstream end of the conveyor. The bowl may also include a conically converging section (8). The conically diverging screen section includes an angle (40) that reduces the coefficient of friction of the solids to a point that allows the cake formed of the solids to slide in a controlled manner forward on the conically diverging screen section with minimal back pressure but without allowing the solid cake to break loose from the conically diverging screen section and slide out of the centrifuge in an uncontrolled manner.
