gap position: 3.0

With a gap position 3.0, a first pre grinding step has been realized. Such pre ground sample might get ground to < 10 mm as desired in gap position 1.0 (see result 2).

We are expecting that a direct grinding with smallest gap position will consumption more time as a stepwise grinding.

The complete lump of metal has been ground within 60 seconds. Lateral support walls and crushing jaws use to free of residues; even higher amounts of sample can be ground this way.

Pre ground sample from result 1 has been used for this trail.

The total sample amount has been ground within 1 minute. Crushing jaws and lateral support walls are free of residues; a grinding of higher amounts is still possible.

The majority of ground particles use to show a length of ~ 8 mm. Only a few particles can be found with a maximum length of ~ 10 mm. The thickness of ground particles use to be around 4 mm and finer.

This cast iron sample use to be very brittle. For a daily grinding of such small amounts, also a Disk Mill PULVERISETTE 13 might be capable to achieve much finer results (with smaller gap settings) if desired.
