Pusher Centrifuge By Fenix Process Technologies Pvt. Ltd.

Pusher Centrifuge is a continuous device for separating solid phase from slurry. It is extensively use in chemical, pharmaceutical, food (common salt) and mineral industries.

The feed slurry flows through the inlet pipe over a rotating distributor and on to a rotating basket, trapezoidal by configuration and at high rpm which revolves concentrically within a fairly larger basket rotating at the same speed. Both the baskets are made from perforated metal. Solids are retained by the screen and water/liquid of the slurry is centrifuged out. The size of solid particles to be separated decides the size of perforation of the screen. The wet cake of solids come out from the end of the basket.

A great advantage of this technology is the possibility to wash the continuously moving product during its passage through the basket.

How it operates: Solids collect on the screen while liquids drain through, The pusher plate rotates with the basket and reciprocates, On the forward stroke- the plate pushes solids along the screen consolidating the solids into a uniform cake, On the reverse stroke- fresh screen is exposed and more slurry is deposited, Cake dries as it moves along the length of the screen and wash liquor may be applied to remove impurities and finally Cake is pushed off the discharge end of the screen and collected through a chute for downstream processing.

Fenix added pre-thickening of dilute slurries in its FXPusher models with Mechanical & Hydraulic drives.
