Structure Design and Analysis of Tube-type Helix Dryer

In order to avoid the disadvantage of fire drying,the dryness technology route is established for slimy materiel based on heat exchange and heat radiation.It is mainly used for fine coal,residual coal,fine mine powder and chemical materiel dehydration.And especially it is an indirect dryness system for fine and washy materiel.A tube-type dryer is designed which is substituted for lamina-type dryer.Heat stress analysis is conducted by ANSYS.The tube-type dryer achieves the separation of heat source and material for safe process.Moreover,the performance of dryer and quality of product are increased with the tube-type construction.At the same time,the manufacture cost and power are reduced.It is valuable to the design and remodel of similar machine.
