A system for drying and preheating small metallic particles such as chips, turnings, borings and the like to remove volatiles therefrom which includes a dryer working in conjunction with a briquetting press. The dryer includes a drying and preliminary combustion chamber includng a revolving drum therein through which the chips pass. The drying and preliminary combustion is heated and is atmospherically sealed and operated with a reducing atmosphere. The volatiles driven from the metallic particles are passed to a combustion completion chamber which is maintained at a temperature sufficient to burn the combustibles and into which air is injected to complete the combustion. The hot metallic particles are thermally insulated and sealed from the atmosphere while being conveyed from the drying and preliminary combustion chamber to the briquetting press where they are compressed into briquettes for subsequent introduction into induction furnaces and the like.
In apparatus for drying and preheating small metallic particles to remove volatiles therefrom of the type having an internally heated drying chamber and conveyor means within the drying chamber for conveying the particles through the drying chamber, the improvements in the conveyor means comprising:
