us4498632a - process for grind-drying wet solid fuel

In a process and apparatus for grinding and drying a solid fuel such as brown coal or lignite to form dust, in a fan type mill, in the presence of a hot drying gas with a low oxygen content, fine components of the fuel in dust form are separated out before the grinding step and dried. The remaining coarser portion of the fuel is introduced into the drying gas before the grinding step, in
