Working principle of drum dryer:
Materials are sent to the hopper of rotary drum dryer by belt conveyor or bucket elevator. The barrel of drum dryer is installed with an angle. Raw materials enter into the barrel from the higher side of the drum dryer, and hot air enters into the barrel from the lower side. Then materials and hot air will mix together in the rotary drum dryer. The moisture will be evaporated by the high temperature of the hot air. The materials go to the lower side when the barrel rotates. Lifters on the inner side of the barrel lift materials up and down, which makes materials and hot air mix completely, so drying efficiency is improved.
