Jaw Crusher PULVERISETTE 1 classic line Model I

gap position 1 (smallest gap)

crushing jaws made of tempered steel

With a start size of 60 mm, the present pieces use to be too big for a direct grinding with e.g. Disk Mill PULVERISETTE 13. A pre crushing is required. For this, we used the Jaw Crusher PULVERISETTE 1 Model I in our first trial. With Model II, up to 95 mm long pieces can be fed for pre grinding.

The complete amount of 5 kg of sample has been ground in smallest gap position to < 8 mm within 5 minutes.

The Model II with its wider grinding chamber might need about 3-4 minutes for the same amount of sample.

The pre ground sample is small enough for feeding to the Disk Mill PULVERISETTE 13 (see result 2).

Disk Mill PULVERISETTE 13 classic line

gap setting: 0,5 mm

grinding disk made of hardend steel casting

2 kg of pre ground sample have been used to demonstrate a fine grinding with Disk Mill PULVERISETTE 13. With a gap setting of 0,5 mm, it took exactly 2 minutes until all sample has been ground.

Afterwards, we checked the present fineness by sieving an aliquot with our Vibratory Sieve Shaker ANALYSETTE 3 Pro and a 500 µm mesh.

Already 92 % of sample use to pass a 500 µm mesh.

To achieve 100 % < 500 µm, still smaller gap setting can be set.
