REDUCTION OF TOTAL COST OF OWNERSHIP

The ANDRITZ hyperbaric disc filter is a very competitive technology for filtration requiring high throughputs as the cost per ton will be less compared to other equipment for high tonnages. Customers can save up to 50% of the total cost of ownership thanks to:

Lower filter cloth consumption
Fully automated and continuous operation
Highest specific throughput generated thanks to the high-pressure system
Small footprint as less space is required for a large filter area

LOWEST RESIDUAL MOISTURE

Moisture content is an important key parameter in many processes. Thanks to the high pressure differential of up to 5.8 bar, the ANDRITZ hyperbaric disc filter can obtain a low residual moisture and thus meets process requirements and save transportation costs because of the reduced weight.

CLEAR FILTRATE

The ANDRITZ hyperbaric disc filter generates a clear filtrate, thus avoiding accumulation of fine particles in the process water circuit and optimizing water recirculation in the system.

YOUR BENEFITS

Up to 50% better in total cost of ownership thanks to lower filter cloth consumption, fully automated and continuous operation, highest specific throughput, and small footprint
Highest throughput and lowest residual moisture due to high pressure differential of 2 up to 5.8 bar and continuous operation
Increased heating value of fine coal and cost savings in thermal drying (or possibly operations without drying) thanks to lower moisture content
Lower cost for conveyors and other peripherals due to continuous operation
Clear filtrate for optimized water recirculation to avoid accumulation of fine particles in the process water circuit
Processing of fine ore
Less emissions to the environment thanks to closed system design

FEATURES

Performance monitoring through inspection window
Field-tested double gate valve
20 stainless steel filter cells per disc for a better internal process
Up to 50% depth of submersion of the filter discs in filter vat, enabling higher throughput and greater flexibility in terms of process parameters
“Snap-blow“ discharge ensures that the filter cake is removed entirely, generating higher throughput with fully automated cake discharge and no manual support required
Stainless steel filter vat for reduced corrosion
Easy-to-change stainless steel filter segments and filtrate pipes for easy maintenance
