hello;
What is the different between "decanter centrifuge" and ordinary "nozzle-disc centrifuge" ? both are for solid-liquid separation .
Thanks for all replies

RE: hello; What is the different bet
Decanter centrifuges handle more solids than the "nozzle-disc" centrifuge but the "nozzle-disc" machines have a greater removal of finer particles due to a greater area.
The "nozzle-disc" centrifuge typically spins on a vertical axis. The conical discs are like having an inclined (or lamella) settler subjected to a high gravity. Solids (with a little more liquid) are ejected through nozzles in the outer solid bowl. There are also "split-bowl" machines having upper and lower bowl sections that can be periodically and momentarily separated to eject accumulated solids.
Bird Machine builds a lot of the Decanter type; see cutaways at

Alfa Laval builds both types.
