Vol. 7, iss. 2

The aim of the present study was raising the innovativeness of sand reclamation units through application of a new material - austempered ductile iron (ADI) - for elements exposed to abrasion wear and impacts. Methods used for casting of ADI blades for disk-type reclamation units were described along with the results of tests and measurements of the obtained hardness, strength and microstructure. The ready ADI castings of blades were next subjected to performance tests to compare them with the conventionally made cast steel blades operating under industrial conditions. The obtained results of the tests confirmed high properties and numerous benefits offered by ADI respetive of cast steel used as a material for elements of sand reclamation units.
