With dewatering belts made of polyester or polyphenylene sulfide, considerably dryer sludges can be attained in serial dryers. These synthetic meshes cover working temperatures ranging from 80 to 200°C and pH values of 1–14. The belts, woven from robust monofilaments and given extensive subsequent treatment, can stand extremely high surface loads. Their specific structure also ensures excellent cleaning of the belt. The patent-pending GKD-PAD seam further develops the conventional hook seam, thereby providing operators with a considerably thinner seam than the previous glue-compressed seam while maintaining the high quality standards. The hook seam, which is covered by a textile pad, is melted and pressed together with glue into the mesh using a novel heating press. The seam is not only easy to use but also particularly durable and persistent. The GKD-PAD seam has proved its worth in various applications, especially in the sewage sludge dewatering and the fruit juice industry running on twin-wire belt presses. — GKD – Gebr.
