glass

Protocol number:	M0097208
Industry:	Chemistry, Ceramics / glass industry
Feed Size:	2-3 cm
Desired Fineness:	< 500 µm
Quantity:	500 g
Recommendation:	Bigger amounts of sample can be ground with our Disk Mill PULVERISETTE 13 to the desired fineness. This sample did not jam the feeding funnel. With particles > 2 cm, we generally recommend a pre crushing (e.g. with Jaw Crusher PULVERISETTE 1 Model I).

Result 1

	Disk Mill PULVERISETTE 13 classic line gap setting: 500 µm
Equipment:	grinding disks made of zirconium oxide (ZrO2)
Feed quantity:	504 g
Feed Size:	2-3 cm
Grinding time:	1,5 min
Final fineness:	< 500 µm
Comments:	Your sample contains a few particles with up to 3 cm length. Such sample can jam the feeding funnel. When sample stick in the funnel, feeding can be supported with a brush, or a pre crushing (e.g. with a jaw crusher) can be performed. Pre crushed sample also might get ground faster. For a grinding of the total amount of your sample, 90 seconds use to be required. With a gap setting of 0,5 mm; particles can pass the gap after one dimension uses to be < 0,5 mm. For this, still particles with up to 0,7 mm can be found in the ground sample. After grinding, gap between the disks uses to be free of residue; only electrostatic charged sample use to remain inside the grinding chamber and can be removed by vacuuming with a soft brush. It is still possible to reduce the gap setting for a finer grinding result.
