Silicium oxide (molten)

Protocol number:	M0098315
Industry:	Chemistry, Ceramics / glass industry
Feed Size:	6 cm
Desired Fineness:	6 mm
Quantity:	0,3 kg
Recommendation:	We recommend using a Jaw Crusher PULVERISETTE 1 Model I for grinding. With standard geometry, higher output of particles < 8 mm is expected. With changed geometry setting, the output of particles < 6 mm length will take much longer.

Result 1

	Jaw Crusher PULVERISETTE 1 classic line Model I gap position 1.0 - changed geometry
Equipment:	crushing plates made of hardmetal tungsten carbide
Feed quantity:	95 g
Feed Size:	app. 1 cm
Grinding time:	3 min
Final fineness:	< 6 mm
Comments:	Previously, the sample has been ground with standard geometry within < 20 seconds. The resulting particles have been used for this trial. It took about 3 minutes until the brittle sample has been ground. Afterwards, all sample use to be < 6 mm as desired. It is also possible using the intact sample for a direct grinding (without a pre grinding step), but total output might be lower compared to this step wise grinding trial.
