Rotary Drum Dryer is used for drying material with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. It can be used for drying many kinds of materials such as limestone slag, coal powder, clay stone etc. It has advantage of reasonable structure, high efficiency, and low energy consumption.

Rotary dryer mainly consists of rotary body, raw material feeding plate, lifting blade, driving and supporting device, sealing ring and etc.

Working principle of operation:
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.
