2015-10-15  Grindability tests which aim to analyse the grindability of biomass to 75 μm are flawed, as the target size for optimal combustion of biomass and the setting for the classifier output from full scale mills is an order of magnitude of higher than this. The BWI test can be used to analyse the mill behaviour of biomass in a tube and ball mill.
