Disc filter upgrade
Stable discs in unstable times
In a disc filter, the discs rotate at about one revolution per minute. Larger disc diameters, higher inlet consistency, or hydraulic turbulence in the vat cause axial deflection of the discs. In the worst case, this can lead to the sectors colliding with the chutes or the cleaning lances. Entire discs may be damaged, entailing unnecessary costs for replacement parts and repair work.
The ANDRITZ disc stabilization system is a package of complementary parts:
- Guide rolls limit the axial movement of the sectors.
- Ring fastening elements enhance the stiffness of the disc and form a smooth running surface for the guide rolls.
- Slide shoes are mounted at the bottom of the vat and prevent serious disc damage caused by chute impacts. The ANDRITZ sliding blocks can be installed from outside the vat without having to remove the sectors or center shaft.
- Reinforced sector holders increase the stability of the disc (only suitable for cassette-type sectors).
The savings are easy to explain:
- Direct savings: No need to replace defective discs and other disc filter parts that have been damaged.
- Indirect savings: Damaged discs may cause unplanned machine shutdowns for emergency repairs.
- And although you continue production while waiting for delivery of the replacement parts, you lose huge sums of money due to the reduced output (with fewer discs in your disc filter).
