Decanter Centrifuge working principle

2 - phase separation

- 1. Feed

- 2. Liquid phase

- 3. Solids phase

- 4. Pond

- 5. Dry beach

The feed suspension is introduced through an inlet pipe into the feed zone of the conveyor where it is accelerated and directed into the interior of the bowl. The settled solids are conveyed axially towards the small end of the bowl by means of the screw conveyor, which rotates at a slightly different speed than the bowl. On the way to the discharge ports the solids are lifted out of the pond up along the dry beach. The solids are finally discharged from the bowl through the discharge ports into the collecting chamber of the casing that surrounds the bowl. From there the solids are removed by gravity through the outlet funnel. The liquid phase forming a hollow cylinder due to the centrifugal force, and flows towards the large end of the bowl. There the liquid overflows adjustable plate dams into the centrate chamber of the casing and is discharged by gravity.

3 - phase separation

- 0. Food

- 1. Light liquid phase
- 2. Heavy liquid phase

- 3. Solids phase

The light liquid phase is discharged into the casing through radial holes in the large end hub. The heavy liquid phase is discharged through axial holes in the large end hub. The liquid radius for the light liquid phase is smaller than the radius for the heavy liquid phase. The liquid level is controlled by plate dams. In order to prevent the light liquid phase from leaving the bowl through the heavy liquid phase outlet, a separating plate is placed on the inside of the large end hub. The heavy liquid phase has to pass under the separating plate before being discharged into the casing. The liquid radius for the heavy liquid phase is controlled by plate dams. The solids are discharged in the normal way.

The bowl, conveyor, inlet tube, outlets, cover and other parts in direct contact with the process media are all made of stainless steel. The discharge ports, conveyor flights and feed zone are protected with materials that are highly resistant to erosion. The frame is made of mild steel with an epoxy enamel finish.
