ANALYSIS OF THE INFLUENCE OF MINI-PIPES DIAMETER IN THE PERFORMANCE OF A NON-CONVENTIONAL ROTARY DRYER

摘要

Conventional rotary dryers are used in many industrial sectors. The present work analyzes the drying of granulated fertilizers in a non- conventional dryer. The major characteristic of this new dryer is the presence of an aerated system consisting of a central pipe from which a series of mini-pipes conduct the hot air directly to the particle bed that is flowing at the bottom. This work has tested several diameters of mini pipes and the better experimental results were obtained with mini pipes of 9 mm.
