Centrifuge Filter Bags

Centrifuges operate on the principle of centrifugal force and a filter cloth to separate solids from liquids. High rotational speed provides high centrifugal force that allows the suspended solid in the feed to settle on the surface of a filter media. Washing processes can be applied at the same rotational speed and in the same centrifuge vessel. Centrifuges are used in discontinuous or batch operations. The use of dedicated our fabrics allows reduction of the residual moisture in the filter cake to minimum values.

Materials

Depending on the grade of automation, bulk size and solid discharge, there are different types of centrifuges in use that require a filter media:

• Bag centrifuge (top discharge).
• Peeler centrifuges (vertical and horizontal).
• Inverting filter centrifuge.

Applications

Typical applications are in life science, Pharmaceutical (API, insulin, oncology), fine chemicals where high purity and closed filter systems are required. Further applications are in food (starch & tapioca), minerals (base and precious metals, coal, fertilizers and in environmental (FGD, gypsum).

Fabrication Solutions

Philite®’s products for centrifuge filters are matched to the filter machines used, whether they are peeler centrifuges, bag centrifuges or inverting filter centrifuges. Our ready-made solutions are based on optimized designs that have been proven in use over many years. Thanks to our wide range of fabrication capabilities and technologies, we are able to provide customer-specific products for optimal fit and function.

Our double layer fabrics technology combines a fine filter fabric (particle retention) and an integrated backing cloth (drainage) in one filter cloth. This fabric is available in a wide range of polymers, such as PP, PET giving our customers an excellent solution based on their chemical and thermal requirements.

Our filter bags meet the highest quality requirements and offer decisive advantages:

• Low downtime.
• High product yield.
• Ease of installation.
• Excellent cake release
