ABSTRACT:
A process is provided for drying raw material that comprises solids and a substantial amount of moisture. The process in its basic form involves the steps of forming the raw material into pellets by extrusion under pressure through a forming die into pellets with the solids compacted into a cohesively secured mass and then drying the pellets thus formed to reduce the moisture to a desired percentage. Raw material that has an excessive amount of moisture such that they cannot be extruded are first mixed with a dry material to reduce the moisture content to the point where they can be extruded.
