curd soap

Protocol number:	M003063
Industry:	Chemistry
Feed Size:	< 2 cm
Desired Fineness:	< 800 µm
Quantity:	90 g
Recommendation:	We recommend using a Variable Speed Rotor Mill PULVERISETTE 14 for comminution of sample.

Result 1

	Variable Speed Rotor Mill PULVERISETTE 14 classic line rotor speed: 20.000 rpm
Equipment:	impact rotor with 12 ribs made of stainless steel + impact bar (item #14.2850.00) + sieve ring: 2 mm trapezoidal perforation for impact bar
Feed quantity:	94 g
Feed Size:	< 2 cm
Grinding time:	3 min
Final fineness:	< 800 µm
Comments:	Before grinding, the massive soap bar has been cut into small pieces with a maximum length of ~ 2 cm. Afterwards, sample have been fed to the machine and got ground within 3 minutes. Because curd soap tends to smear over sieve ring and rotor, we ground the sample with the optional impact bar. The resulting particles of sample use to be < 0.8 mm in diameter; a few particles use to show a length of ~ 2 mm. It might be possible using a smaller sieve ring for when a pre grinding step might be performed or sample will be embrittled previously.
