Abstract
A method of retrofitting a centrifuge comprises disassembling a known centrifuge and replacing the conical beach section with a shorter beach section, i.e. a beach section having a greater slope. The screw conveyor is replaced with another screw conveyor having outlet nozzles adapted to impart rotational movement to the inlet feed.
Claims5
A method of retrofitting a decanting centrifuge, comprising the steps of:
- a. replacing a bowl section of the centrifuge outer body with a longer bowl section;
- b. replacing a conical section of the centrifuge outer body with a conical section defining a greater slope angle;
- and
- c. replacing a screw conveyor of the centrifuge with a screw conveyor having nozzles therein adapted to impart rotation movement to feed liquid.

A method of retrofitting a decanting centrifuge, comprising the steps of:
- a. adding a segment of a bowl section of the centrifuge outer body, thereby making the bowl section longer;
- b. replacing a conical section of the centrifuge outer body with a shorter conical section, wherein the combined length of the added segment of the bowl section and the shorter conical section is substantially the same as the replaced conical section;
- and
- c. replacing a screw conveyor of the centrifuge with a screw conveyor having means therein adapted to impart rotation movement to a slurry input to the centrifuge.
