Drying of granular materials using an induction heated double-screw conveyor

Martel, Sylvain, 1980- January 2008 (has links)
An experimental study of the drying of sand using an induction heated double-screw conveyor (screw shaft radius 0.0381 m, blade radius 0.0883 m, thread pitch 0.0869 m, heated length 1.96 m) is presented. The main aim was to improve the understanding of the operating characteristics of the dryer and obtain data for testing and refining future mathematical models. In the drying tests, power to the induction coils was controlled to obtain uniform screw shaft temperatures between 150 to 250°C. The angular rotation speed of the screws ranged between 2.5 to 15 rpm; and inlet moisture content (mass fraction of water) was varied between 0.1 to 10 %. The sand used had a mean effective diameter of 0.38 mm, particle density of 2743.7 kg/m3, and uncompacted dry bulk density of 1508.2 kg/m3. The results of sand characterization tests, conveying tests without induction heating, and drying tests are presented and discussed.
