Effect of moisture on energy-size reduction of lignite ...

2020-6-15  Results show that the energy-size reduction process for grinding lignite is markedly influenced by moisture occurrence and content. Removing surface moisture from 37.90% to 16.61% (the air-dried condition) resulted in a slight increase of input energy by 0.04 kWh.t −1 per 10 s. However, with further drying inherent moisture to 0%, the ...
