Continuous Centrifugal Dehydrators are centrifugals with a filtering basket. They assure the separation, the drying and eventually the continuous washing of a solid phase suspended into a liquid phase.

They are recomended for:

- centrifugal drying of mineral wellcrystallised products.

- centrifugal drying of organical synthesis products.

- centrifugal drying of fibrous products

- drying of crystals of size larger than 75 microns

Special types for:

- operation in dangerous atmospheres

- high and low pressure

- high and low temperature

- sterile atmosphere

Construction:

- in mild steel, stainless steel or special alloys

- truncated conical basket rotating at high speed, equipped with a filtering medium adapted to the

handled product

- screw conveyor rotating at a speed different from that of the basket

- external casing to collect the dried product the mother liquors and the wash liquors

- slurry feed pipe

- rotating gear box with oil bath controlling the relative speed between basket and srew conveyor

- safety device preventing overloading of the rotating gear

- wash pipe

- seal permitting operation in dangerous atmosphere

- outlet for the wash liquor

- outlet for the filtrate

- outlet for dry product

Operation:

- the slurry to be treated (on the sketch) is fed through feed pipe D.

- under the centrifugal effect, the solid product (on the sketch) is thrown against the innner wall of

the basket

- it is then continuously discharged by the screw conveyor B through outlet K.

- the filtrate liquid (on the sketch) is continuously discharged through outlet J

- the wash pipe G permits the inlet of a liquid to wash the treated product during centrifugation and

before discharge
