|With the desired Cutting Mill PULVERISETTE 15, smaller amounts of sample can be ground to < 2 mm. It is also possible that smaller sieves can be used for grinding to e.g. < 1 mm (with higher amounts of residue inside the grinding chamber).|
rotor with straight cutting edges and fixed knives made of tool steel
+ sieve insert: 2,0 mm trapezoidal perfotration made of stainless steel
||app. 1,5 kg|
||output: 1,36kg; < 2 mm|
Complete sample amount has been fed within 3 minutes. After a total of 4 minutes, grinding process has been interrupted. Already 1,36 kg of ground sample could be found inside the collecting pan. A higher amount of residue use to be left in the grinding chamber, sticking lightly by electrostatic charge (typical for most plastic samples).
It is possible that a longer grinding time will raise the output somehow. Nevertheless, grinding chamber can be cleaned rapidly by vacuuming with a soft brush. Even higher amounts might be ground this way.
Also a Universal Cutting Mill PULVERISETTE 19 might be capable to grind such samples with several advantages (regarding cleaning, handling and available accessories).
