For this kind of sample, we recommend using a cutting like PULVERISETTE 15 or Universal Cutting Mill PULVERISETTE 19. |

Equipment: |
Rotor with straight cutting edges and fixed knives made of tool steel + sieve insert 0,75 mm trapezoidal perforation made of stainless steel |

Complete sample amount has been ground within 60 seconds. Sieve insert and grinding chamber are mainly free of residues. A rapid cleaning can be performed by vacuuming with a soft brush.
For a comminution of up to 100 g of sample, about 4-5 minutes might be needed.

Instead of a 0,75 mm sieve insert as used in result 1, a 0,5 mm sieve insert has been used for this trial. Complete sample amount has been ground within 60 seconds. Sieve insert and grinding chamber are mainly free of residues. A rapid cleaning can be performed by vacuuming with a soft brush.
We are guessing that a comminution of up to 100 g of sample will also take about 4-5 minutes.

In our last trial, a 0,25 mm sieve insert has been used for the comminution of sample. Just the previously performed trials, the complete sample amount could be ground within one minute. With all 3 trials, some particles have been able to pass the openings of the sieve insert longitudinal. For this, still longer pieces can be found after grinding.
We are guessing that also about 5 minutes should be necessary to grind 100 grams of sample.
