Description of Nordic Abrasion Machine
Nordic Abrasion Machine has been developed for testing the resistance to abrasion/wear from studded tyres. Test is performed on natural stones and aggregates between 11.2 mm and 16 mm. Test consists of rotating aggregates in drum with steel abrasive balls and water. The machine consists of an electronic control unit and a rolled stainless steel drum having an inside diameter of 206.5mm, internal length 335mm and thickness of 6mm. The drum is rotated at a speed of 90±3 r.p.m. 3 mixer arms are installed inside of the drum to allow balls and aggregates to be mixed properly. The abrasion loss rate of aggregates is calculated after specified number of revolutions stated in the related standard.
