'''Spiral dryer''' is widely used in mining, metallurgical, chemical industry, etc. The machine combines the advantages of pneumatic transmission and conduction heating technology and uses air or inert gas as carried medium. The material film lifted along with helix at inner wall will obtain heat continuously and will be dried within 3-15 seconds. | '''Spiral dryer''' is widely used in mining, metallurgical, chemical industry, etc. The machine combines the advantages of pneumatic transmission and conduction heating technology and uses air or inert gas as carried medium.
