Description

This article describes an implementation of the vibrating screen sizing methodology described by Metso (Viilo, 2011), coupled with the classification methods of Whiten and White (1977), Dehghani et al. (2002) and Firth and Hart (2008).[1][2][3][4]

The Metso vibrating screen model may be invoked from the Excel formula bar with the following function call:

=mdUnit_Screen_Metso(Parameters as Range, Size as Range, Feed as Range, OreSG as Range, Rows as Range)

Invoking the function with no arguments will print Help text associated with the model, including a link to this page.
