Because this causes particularly great wear on the ship unloaders, the port commissioned the company Kalenborn France to provide wear-proof lining for its cranes. The challenge: to protect chutes and filling shafts as well as channels and pipes. A suitable form of wear protection had to be found for all elements.
Kalenborn decided on a combination of three materials: KERAFLEX, KALMETALL and KALOCER. The transfer chute, whose impact surface has to withstand a material throughput volume of 4,000 tons an hour, was reinforced with KERAFLEX. The ceramic plates vulcanised into rubber mats have an extremely hard and wear-proof surface. Impact resistance is provided by the 10-mm-thick rubber layer and optimal vulcanisation of the components. The unloading surfaces of the conveyor belts were also fitted with KERAFLEX. Because the conveyor belts work at a speed of between 3.6 and 5 metres a second, high wear protection is particularly important here.
Feeding chutes and filling shafts were lined with KALMETALL-W and KALOCER. The combination of the KALMETALL-W hard overlay-welded plates and the KALOCER high alumina ceramics unites optimal wear protection with outstanding gliding properties.
A consignment warehouse has meanwhile also been constructed on site: here the employees in charge of facility maintenance can independently remove and process the required materials.
