ANDRITZ hyperbaric disc filter HBF

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 ANDRITZ hyperbaric disc filter HBF to be a superior solution for mining applications in combination with high throughputs.
