Comprehensive understanding of grinding aids
The majority of commercial grinding aids have boiling points and decomposition temperatures that are significantly above the grinding tempera - ture (e.g. PG, DEG, TEA, see Table 1). Their vapour pressures are low but sufficiently high that they are presumably dispersed via both mechanisms, gas phase transfer as well as surface contact transfer.
