	Universal Cutting Mill PULVERISETTE 19 Speed 300-3000 rpm
Equipment:	standard rotor with V-cutting edges and fixed knives made of tool steel + sieve cassette: 1 mm trapezoidal perforation + sample exhauster system with cyclone separator
Feed quantity:	38 g
Feed Size:	< 4 cm
Grinding time:	2 min
Final fineness:	< 1 mm
Comments:	Grinding of sample had been performed without any problems. Even higher amounts of sample can be ground; If a higher amount of sample should be ground daily, a rotor with knives made of hardmetal tungsten carbide will show a much longer durability. With the requested cyclone separator, also smaller sieve cassettes can be used for grinding of this kind of sample.
