Hammer mill could crush straws into canicaceous materials, which can be processed to feedings and biomass fuel. Compared to traditional fuel, biomass fuels have the same volume calorific value and the features of strong combustion, long burning time and quick ignition, which is another ideal replacement of traditional fuels.
