WRT spiral belts are mostly applied in transportation and filtration or separation applications for waste water treatment , in municipal plants, private plants, etc. A spiral belt, also called ( spiral fabric, link fabric or belt filter ) is the ideal solution for dewatering cases. A long experience in the field of industrial fabrics and a constant attention to ecology have allowed WRT to develop a wide range of spiral mesh belts for mechanical dewatering of liquid to solid for any kind of material.Our product range covers all sludge belt press liquid filtration applications, such as: Dewatering of inert sludge from quarries or mines , Dewatering of biological or chemical sludge from municipality sewage plants ,Pressing of grapes, fruit and others.WRT spiral belts are also used at critical stages of Particle Board, Medium Density Fibreboard (MDF), Oriented Strand Board (OSB), Hardboard & Wood Veneer processes and for the manufacture of ceiling tiles, etc.
WRTSpiral belts are made with special first quality yarns in 100% polyester. Every WRT spiral belt is heat-set granting a high degree of stability and long running life. Advantages of our spiral belts are among others: strength, flat surface, good air permeability, stable property against heat and moisture, low thermal shrinking, less elongation at heat and a long lifespan.Spiral belts are connected spirals by use of cross wires. The spirals contain filling wires, through which the open area is determined.
Features & Benefits: High strength ,Stable under high tension ,High resistance against abrasion , Can be made on size on site ,Seamless - the seam has exactly the same strength of the belt ,Can be repaired easily on site ,Durability, smoothness and good dirt release ,Filled or unfilled to achieve different filtration characteristics(Air permeability: 250 to over 1000 CFM) ,Sealed edges for lasting, economical solutions . Widths up to 6 linear m ,Standard lengths to 60-80 m .pH range 2 to 8.
