Result 1

	Cutting Mill PULVERISETTE 19 large speed 50-700 rpm
Equipment:	Disk milling cutter rotor with indexable inserts and fixed knives made of tungsten carbide + 4 mm sieve cassette made of stainless steel
Feed quantity:	1 kg
Feed Size:	< 13 cm
Grinding time:	5 min
Final fineness:	< 4 mm
Comments:	Also standard rotor and rotor made of tungsten carbide with V-cutting edges are available and possible to use. If a content of stones or nails could not be excluded, we recommend using the disk milling rotor for a fast fixing if an insert becomes damaged. The sample was been fed in portions. An output of 250 g/min is possible without problems. After grinding, only a minimum amount of sample was left on top of the sieve cassette. A grinding of higher amounts is possible. The maximum diameter of the resulting sample is 4 mm, the longest pieces show a length of < 1,5 cm.
