Принцип работы

decanter_small_end_hub1 Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that results from the rotation then causes sedimentation of the solids on the wall of the bowl.

The conveyor rotates in the same direction as the bowl, but slightly slower, thus moving the solids towards the conical end of the bowl. A special Liquid Lock conveyor design (patent pending) accelerates light particles before discharge for optimum separation. It also facilitates the small footprint.

Separation takes place throughout the entire length of the cylindrical part of the bowl. Relatively low G-force is needed for the i-DW decanter to deliver good performance in terms of capacity and cake dryness. This contributes to low power consumption.

The clarified liquid leaves the bowl by flowing out of the casing via special patented energy saving Power Tubes that enable lower speed of discharged effluent. The cake leaves the bowl through the solids discharge openings into the casing.
