Spiral Mesh Belts
Averinox 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 Averinox to develop a wide range of spiral mesh belts for mechanical dewatering of liquid to solid for any kind of material.
Averinox has a 24-hour service facility available that can provide immediate assistance, supply and/or mounting of metal conveyor belts.

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
Averinox 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.

Averinox Spiral belts are made with special first quality yarns in 100% polyester. Every Averinox 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.
