Coal mills are designed to handle hard and brittle materials whilst biomass fuels are fibrous and often rather soft. The biomass particles can be significantly larger than coal particles and still burn out completely, so the classifiers will need to be modified or run in a different way to avoid unessecary grinding work that will increase power
