Result 1

	Universal Cutting Mill PULVERISETTE 19 Speed 300-3000 rpm
Equipment:	rotor with V-cutting edges and fixed knives made of tool steel + sieve cassette: 0.25 mm trapezoidal perforation
Feed quantity:	65 g
Feed Size:	8 cm (long)
Grinding time:	8 min
Final fineness:	< 0,25 mm
Comments:	The sample was fed in succession of quantities of app. 10g within 6 minutes. After a total grinding time of 8 minutes, grinding has been interrupted. We found an output of 45 g of fine ground sample inside the collecting vessel. About 20 g of sample remains mainly by electrostatic charge inside the grinding chamber. A small quantity of sample use to lie loose on top of the sieve cassette. Openings of the sieve cassette are mainly free of residues. For this, even higher amounts of sample can be ground this way. Cleaning can be performed rapidly by vacuuming with a soft brush.
