D5LLTC decanter centrifuge from Andritz

Andritz decanter centrifuges are designed for reduced space requirement and power consumption at identical throughput and offer unrivalled performance.

ANDRITZ, the world leader in sludge treatment technology, has once again revolutionized the drive system for decanter centrifuges: after the double drive with energy re-circulation, the new TC decanter centrifuge is the first centrifuge with a co-axial driving system, featuring a novel synchronous motor and coupling type. It is protected by worldwide patents and is used in centrifuges for thickening and/or dewatering of WWTP sludge.

The drive system is unique in that:

The new-generation motor comes without bearings and fixed windings

It is directly coupled to the Cyclo reducer and therefore acts both as main and secondary motor, controlled by frequency inverter, in order to optimize the bowl and the scroll speed.

It has very precise differential speed and torque control.
