Abrasive material derived from ferroalloy slag is applied for metal surfaces cleaning.
Abrasive material grains of 0.16 - 2.5 mm size comes to no less than 91% from a lot mass, where the grains content from 0.63 mm to 2.5 mm inclusive comes to no less 80% from the whole mass. The grains content of size less than 0.16 mm does not exceed 4%, and the grains content of 2.5-4 mm size comes to no more than 5%.
Granulometric analysis – 0,16-2,5 mm
Bulk density – 1200-2000 kg/m3
Abrasive capacity – no less than 0,01 g/sm2
