Iron (pellets)

Protocol number:	M001156
Industry:	Metallurgy
Feed Size:	< 1cm
Desired Fineness:	100% < 75 µm; d50 < 30µm
Quantity:	20 g
Recommendation:	A grinding of such a brittle sample use to be possible with a Vibratory Micro Mill PULVERISETTE 0. To reach the desired fineness, about 10 minutes of grinding use to be necessary.

	Vibratory Micro Mill PULVERISETTE 0 amplitude: 2,0 mm
Equipment:	mortar made of stainless steel with 50 mm Ø steel grinding ball
Feed quantity:	20 g
Feed Size:	< 1 cm
Grinding time:	10 min
Final fineness:	100% < 75 µm 50% < 19,6 µm
Comments:	The sample use to be brittle enough for a direct grinding without a pre grinding of up to 1 cm long pieces. After 10 minutes of grinding, the sample has been ground to a fine powder. To determine the present fineness, we used our Laser Particle Sizer ANALYSETTE 22 Compact. The desired task of 100 % < 75 µm and d50 < 30 µm has been fulfilled. A longer grinding time is not necessary.
