    Mass size fractions are not conserved through grinding devices (SAG mill and ball mills). Therefore there is no mass conservation equation for size fractions around the grinding devices and consequently there is no node for grinding devices in mass size fraction networks. The same reasoning applies to Cu-by-size fractions.
