Operating principle of the pusher centrifuge

1
1
Suspension inlet

The centrifuge is continuously fed with the suspension to be separated (solid-liquid mixture) via the inlet pipe. In case of poor flow characteristics, the feed is effected via an inlet screw conveyor (not shown).

2
2
Suspension distributor

The distributor accelerates and distributes the suspension over the entire periphery of the sieves in the filling area of the first basket stage. Ferrum offers various application-specific distribution systems for even and gentle acceleration and distribution of the suspension.

3
3
First basket stage

he greatest part (approx. 80%) of the liquid is already filtered out in the feed zone of the first basket stage, where a stable cake forms. The first basket stage performs, along with a rotational, also an axial pusher movement (oscillation movement).

4
4
Second basket stage

The cake is pushed in annular sections by each pusher movement from the first to the second basket stage.

5
5
Solids discharge

After the second basket stage, the solids leave the centrifuge via the discharge channel and the solids housing. Depending on the application, different discharge systems are used.

6
6
Product washing

If necessary, impurities in the mother liquor are washed out. The wash liquid is applied continuously over the cake via several adjustable wash nozzles.

7
7
Filtrate housing

The filtrate (filtered mother liquor and wash liquid) is collected in the filtrate housing and drawn off. Depending on the application, different filtrate housings and filtrate cyclones are used.

8
8
Filtrate separation

If necessary, the filtrate can be drawn off separately in each filtrate zone by means of separation plates fitted in the filtrate housing and disposed of or reused (e.g. counterflow washing).

9

Rinsing

The centrifuge process area is cleaned using rinsing liquid supplied through optimally arranged cleaning nozzles. Periodic rinsing prevents the crystal formation in the sieves and deposits in the solids housing.

The greatest part (approx. 80%) of the liquid is already filtered out in the feed zone of the basket, where a stable cake forms. The pusher plate oscillates forward and backward and pushes the cake towards the rear AND front solids discharge.
