Abstract
A process and apparatus for drying material, in which a previous dried material is mixed into the wet material to be dried to produce a dried mixture of different particle sizes. The process for drying material requires less industrial equipment implemented in a more economical and simpler plant that can be operated with low energy and maintenance requirments. The amount of fine material obtained after drying is measured and the amount of fine previously dried material mixed into the wet material to be dried is then set in inverse proportion to the quantity of fine dried material produce.
