ANDRITZ Separation - ANDRITZ Group

- Model HBF - Hyperbaric Disc Filter



Hyperbaric filtration guarantees low residual moisture in combination with high throughputs. The continuous filtration process eliminates all the surge capacity equipment required in batch-type filtration systems. The ANDRITZ hyperbaric disc filter is the right choice inside one unit for continuous filtration, highest solids throughputs, lowest residual moisture, and clear filtrate – and all of that with minimized footprint.

Continuous filtration within the pressure vessel ensures continuous feed and power consumption. This eliminates all the surge capacity equipment required in similar batch-type filtration systems. Hyperbaric filtration has been proven in a large number of plants operating worldwide (Europe, China, Brazil, Russia, USA, Australia, South Africa, India, and Chile).

Calculations taking account of the capital and operating costs prove the hyperbaric filter (HBF) to be a superior solution for mining applications in combination with high throughputs.
