burned lime

Protocol number:	M0097205
Industry:	Construction materials
Feed Size:	3 cm
Desired Fineness:	90 µm (up to 90 % < 90 µm can be reached)
Quantity:	~ 0,5 kg (or higher)
Recommendation:	A grinding of higher amounts is possible with Disk Mill PULVERISETTE 13. With a start size of up to 3 cm, we recommend pre crushing bigger particles before feeding.

Result 1

	Disk Mill PULVERISETTE 13 classic line gap setting: 100 µm (smallest possible gap setting)
Equipment:	grinding disks made of hardened steel cast
Feed quantity:	600 g
Feed Size:	3 cm
Grinding time:	4 min
Final fineness:	90 % < 0,09 mm
Comments:	Complete sample amount has been fed and ground within 4 minutes. A few of the particles show a maximum length up to 3 cm. This might be potential candidates which can jam the feeding funnel. For a constant feeding without jamming, we recommend only using particles < 2 cm. In our trial, all particles have been fed without problems, a support of feeding with a brush has not been necessary. Because a bit of the fine dust escaped the feeding funnel, we were placing the tube of a vacuum cleaner next to the machine. After 4 minutes, all samples have been ground. Mainly electrostatic charged sample use to remain inside the grinding chamber. Cleaning can be performed rapidly by vacuuming with a soft brush. To determine the achieved fineness, we sieved out an aliquot of ground sample with our Vibratory Sieve Shaker ANALYSETTE 3 Pro and a test sieve of 90 µm mesh. Already 90 % of ground material is able to pass the mesh of the test sieve.
