Paper Title
Experimental Research The Moisture Migration Characteristics Of Coal Material

Abstract
Moisture migration characteristics play an important role in bulk solids handling and conveying. This paper investigates the moisture migration characteristics of coal after cyclic drainage. Based on experimental research, the relationship between moisture content and material height is approximately linear after 24-hour oscillation. Besides, this work also shows how the mass median diameter affects average moisture migration rate of coals with two different saturation levels.
