EN 1097-9; UNI 8520-13-16
Nordic Abrasion
Machine has been developed for testing
the resistance of aggregates to wear by abrasion from studded tyres. The test
is performed on natural or artificial stones and aggregates between 11.2 mm and
16.0 mm.
The test consists of a rotating aggregate in a drum containing steel
abrasive balls and water. The machine consists of an electronic control unit
and a rolled stainless steel drum having an internal diameter of 206.5 mm,
internal length of 335 mm and thickness of 6 mm. The drum is rotated at a speed
of 90 ± 3 r.p.m. 3 wings are installed inside of the drum to allow the balls
and aggregates to be mixed properly.
The abrasion loss rate of aggregates is calculated after the specified
number of revolutions stated in the relevant standard.
110 V 60Hz version should be mentioned on order if required.
11,1 mm diameter steel balls ( 3.5 kg.) should be ordered separately.
The Nordic
Abrasion Machine is supplied complete with;
Steel Balls, Ø 15 mm, 7 kg
