Experimental Study of the Volume Drying Shrinkage
Low-temperature and humid drying experiments [temperatures of 20–30 °C; relative humidity (RH) of 40–60%] were conducted to investigate the drying shrinkage of lignite at low temperatures. The moisture content and volume variations of lignite during low-temperature drying were measured to analyze the change in the water content and volume drying shrinkage rate under low-temperature drying
