The SIEBTECHNIK TEMA TWINCONE decanter centrifuge is a decanter centrifuge with a second bowl cone fitted downstream.
The solid matter is separated and concentrated by sedimentation in the first bowl cone. The second bowl cone has a larger diameter, so a lower head of solid matter forms ahead of the worm channel. On this second bowl cone the product can be washed and the washing liquid drained off separately from the mother liquor.
Because of the larger diameter great centrifugal forces are exerted on the second bowl cone, and these help dewatering.
All SIEBTECHNIK TEMA TWINCONE decanters are adapted individually to the product conditions and system requirements.
The suspension fed in through the inlet pipe is accelerated in a relatively small bowl diameter designed to suit clarification requirements.
The solid matter that has settled in the clarification bowl is pre-thickened by means of a short cone. Here the filling volume of the bowl and therefore the length of the dewatering section can be steplessly adjusted by means of a weir plate.
The pre-thickened solid matter is discharged over the discharge rim at the end of the clarification bowl and into a considerably larger dimensioned drying cone downstream.
Here the solids cake is broken up and redistributed with a lower head of material ahead of the worm channel to match the larger cone volume and accordingly smaller filling volumes between channels.
At the same time the larger diameter of the drying cone guarantees high xg numbers at relatively low rotor speeds. The residual liquid is drained off through a separate liquid outlet in the centrifuge housing.
The solid matter carry-overs in the redewatering centrate are small and because of recirculation into the centrifuge are not to be rated as a loss or a load.
Product washing is also possible with the downstream drying cone, the wash fluid then being drained off separately from the mother liquor.
