Bond Grindability Test Procedure. The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured.

Oct 15, 2015· 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.
