Nordic Ball Mill

Standard: EN 1097-9

Product number: 42-06300

A sample of aggregate with a fraction of 11.2 – 16 mm is tumbled together with steel balls and water in the rotating blast drum. Three ribs, mounted on the inside of the drum, improve the mixing.

The contents are tumbled in the drum with an abrasive effect. After the prescribed number of revolutions, the contents are emptied and the aggregate sample is sieved to determine the amount of worn material.

Abrasion loss is calculated after a certain number of revolutions specified in the standard.

The machine can run two Nordic ball drums simultaneously, or can be used for Micro Deval tests with up to 4 standard drums. Through a selector you select either the Micro Deval test with a speed of 100 rpm, or the Nordic ball test with a speed of 90 rpm.

The machine has the dimensions 1270 x 590 x 400 mm

You do not have to buy all the drums at the same time, but can supplement with the drums you want.
