Result 1

	Mini Cutting Mill PULVERISETTE 29 speed: 6000 revolutions per minute
Equipment:	sieve insert: 4 mm square perforation rotor: Rotor with straight cutting edges material: hardened stainless steel
Material attributes:	SIM-cards
Feed quantity:	1,1 g
Feed Size:	12 mm
Grinding time:	40 seconds
Final fineness:	majority < 3 mm
Comments:	Seven SIM cards were provided. Due to their light weight, we fed the cards in together using the optional helix plunger. The grinding noise was slightly harsher, but still acceptable. After approximately 30 seconds, all cards had entered the grinding chamber. The grinding noise ceased after about 40 seconds, and the mill was stopped. Minimal residue remained in the grinding chamber. For quick cleaning of the grinding chamber, we recommend using a vacuum cleaner and a soft brush. Compressed air can also be used.
