turquoise (China)

Protocol number:	M0098239
Industry:	Chemistry, Geology / mineralogy
Feed Size:	3 – 4cm
Desired Fineness:	< 1 cm
Quantity:	up to 40 kg
Recommendation:	For this sample we recommend a Jaw Crusher PULVERISETTE 1 Model I. For higher amounts of sample Model II is beneficial.

Result 1

	Jaw Crusher PULVERISETTE 1 classic line Model I gap position: 1.0 (smallest gap)
Equipment:	crushing jaws made of tempered steel
Feed quantity:	1 kg
Feed Size:	3 – 4 cm
Grinding time:	90 s
Final fineness:	< 8 mm
Comments:	The Jaw Crusher PULVERISETTE 1 Model l is suitable for a crushing of this kind of sample to < 8 mm. Higher amounts can be ground without problems. Maximum output will be achieved when the grinding chamber will be almost filled completely. At the end of the grinding process, the output will become lower too. For a desired amount of 40 kg, we are guessing that about 45-50 minutes might be necessary. Model II with wider crushing jaws might be faster for grinding an equal amount (approximately 30-40 minutes) .
