DECANTER CENTRIFUGES & PLANTS FOR SOLID/LIQUID SEPARATION HILLER DRIVE SOLUTIONS FOR DECANTERS DRIVE SOLUTIONS FOR DECANTERS Hiller decanter centrifuges consist fundamentally of a rapidly rotating bowl for generating high centrifugal forces and a screw conveyor that clears the solid material in the bowl. The requirement for the screw conveyor is to generate a high torque at a lower differential speed in relation to the bowl. HILLER offers 5 DRIVE SYSTEMS, that fulfil these requirements. ■ very good operability ■ permanent display of all important operating data All drive systems are also available for applications in EX zone. ■ individually programmable control response ■ clear interface between centrifuge and plant ■ remote monitoring possible
