Comparative evaluation of three classical sizing methods of

1. Three screening methods can be used to select the vibrating screen: ACM, PKM and KM.
2. No screening method can calculate screen aperture smaller than 0.297mm.
3. The KM is not able to calculate screens with apertures smaller than 1.0mm.
4. The smallest deviations were obtained by the PKM, with Gneiss as feed material, screen apertures ranged from 4.76mm to 19mm and moisture ranged from 2.12% to 3.3%.
