Such types of spiral dryer fabrics for belt press filter are stuffed with filler mono-filaments in the spiral loops to reduce the permeability. These spiral fabrics are widely used for sludge or sewage dewatering in many industries such as paper mills, effluent treatment plants, mining and mineral industry.
Polyester spiral press filter belt is also a monofilament polyester fabric but not like a woven fabric, instead this is a polyester fabric with spiral twisted wires where pins hold the spirals together like a chain.
Most of the polyester spiral press filter belt is being used within the dewatering industry to separate sludge from water within filter belt presses. Polyester spiral fabric belts are also being used within the food industry to dry fatty milk and whey powders on, or to separate solids from liquids. Other applications and industries are chemicals, pharmaceutical, coals washing and paper pulp washing. The polyester spiral fabric can be equipped with or without filling yarns which enables to adjust and customize the air and liquid permeability.
