Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industry and coal in coal mine, etc. Rotary dryer can be widely used to dry various materials, and it is simple to be operated. Working principle:
Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator.The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.
