Attrition

Abrasion refers to the material loss on the surface of a component caused by mechanical stress, particularly friction. This type of wear occurs on coatings, textiles, rubber components, metals, and fabrics and leads to the formation of fine particles. In filtration technology, abrasion is relevant in two ways: first, filter media must be abrasion-resistant to withstand continuous stress from particle flow, cleaning processes, and the mechanics of the equipment; second, abraded particles themselves can enter the process as contaminants. GKD uses high-strength metal and plastic monofilaments for its process belts and filter fabrics, which provide high abrasion resistance through optimized weave designs. Smooth surfaces minimize adhesion and protect the fabric. Correct installation, sufficient support, and defined scraping mechanisms also reduce abrasion. Wear measurements and laboratory tests allow filter media to be designed for specific load profiles, ensuring long service life and process reliability.
