Vibro mills : For grinding and producing fine particle size less than 1 micron in a cost effective manner. Since high impact like conventional costly ball mills are not required in vibro mills. Instead a large number of low energy impacts are necessary using small grinding media with high vibration or rotation rate.
Recommended grinding media : Cylinders of Ø 6.0 mm to Ø 20.0 mm.
Recommended media charge : 60 - 70% of mill’s useful vol.
Calculation of media load
Vibro mill net volume is 350 Ltr charging with Ø 12.5 mm cylinders.
60% mill’s vol = 350 Ltr x 1.6 kg/Ltr (Bulk density of Steatite media)
That is 336kg of Steatite grinding media required for 350 ltr capacity vibro mill
