The dryer de-agglomerator device (22) reduces the moisture content of the incoming ore, especially in circumstances where the low-grade iron ore has previously been stored as wet tailings or processed by wet methods. The dryer includes a tube and a hot gas generator, which most often will use natural gas or heavy fuel oil as fuel.
