THE ABRASION BEHAVIOUR OF MATERIALS FOR DREDGER COMPONENTS, DUE TO SAND/WATER MIXTURES

Abrasion of dredger parts under the influence of water/sand mixtures, is related firstly with the nature of the type of sand in the sand/water mixture and the specific gravity of the mixture, and secondly with the type and quality of the component materials. A number of fundamental forms of abrasion are distinguished. Studies on the abrasion subject have been performed in two ways, namely the fundamental research work in the laboratory of the Mineral Technological Institute, and field research work in actual dredger practice. The well-known standard wear tests have been carried out in the laboratory for a long time, additionally field research results have motivated abrasion testing stations to be developed for directed, accelerated studies. This equipment has allowed the testing of construction of a wide variety of types and composition. These test have provided inside knowledge of the wear behaviour of several types of material. The state of the materials under review, i.e. structure, hardness and mechanical properties are the variable factors. In conclusion the results are being used to optimise the selection of materials for actual service duties.
