Ferro vanadium

Protocol number:	M0097144
Industry:	Metallurgy
Feed Size:	< 1 cm
Desired Fineness:	< 500µm (< 150µm reached)
Quantity:	270 g
Recommendation:	We recommend using Vibration Cup Mill PULVERISETTE 9 for a rapid grinding to desired fineness. Also a planetary mill like Planetary Mill PULVERISETTE 5 classic line can be used for a dry grinding of higher amounts.

	Planetary Mill PULVERISETTE 5 classic line with 4 grinding bowl fasteners main disk speed: 360 rpm
Equipment:	250 ml grinding bowl made hardmetal tungsten carbide (WC) + 6x 30 mm ø WC grinding balls
Feed quantity:	270 g
Feed Size:	< 1 cm
Grinding time:	5 min
Final fineness:	< 500 µm
Comments:	After 5 minutes of dry grinding, all sample has been comminuted to < 500µm. Sample is not sticking to bowl or balls, a longer dry grinding time is still possible to achieve a better grinding result (see result 2).

	Planetary Mill PULVERISETTE 5 classic line with 4 grinding bowl fasteners main disk speed: 360 rpm
Equipment:	250 ml grinding bowl made of hardmetal tungsten carbide (WC) + 6x 30 mm ø WC grinding balls
Feed quantity:	270 g
Feed Size:	< 1 cm
Grinding time:	10 min
Final fineness:	< 200 µm
Comments:	After a total grinding time of 10 minutes, fineness has been determined by sieving with a 200 µm mesh test sieve on Vibratory Sieve Shaker ANALYSETTE 3 Pro. All particles have been able to pass the sieve. Biggest particles might have a length of ~ 150 µm. Still longer grinding times are plausible.

	Vibrating Cup Mill PULVERISETTE 9 speed: 1300 rpm
Equipment:	100 ml grinding set made of tempered steel (with 1 disk + 1 ring)
Feed quantity:	270 g
Feed Size:	< 1 cm
Grinding time:	2 min
Final fineness:	< 150 µm
Comments:	After 2 minutes of grinding at 1300 rpm, all sample use to be ground < 150 µm. Because sample is not sticking to puck, ring or grinding set, a longer dry grinding time is still possible to maintain a better grinding result. For a grinding to < 500 µm, probably 1 minutes of grinding might be fulfilling with our Vibration Cup Mill PULVERISETTE 9.
