Dewatering conveyors are produced solely under the company’s own management at Hessels Zeefbanden. Including the metal rods that are processed within them. These metal rods in different alloys are rolled at the ends after which they can be nailed on to the dewatering conveyor belts. The rods are rolled by heating the metal. Heating the metal produces much fume and dust emission, which is hazardous to staff. After rolling, hazardous substances are also produced. The rods are taken to what is commonly referred to as a “flash-off” location where they can flash off for a while longer. The challenge was, therefore, to not just provide the customer with an extraction solution for the metalworking process, but also a suitable one for this post process.
