A rotary dryer consists of a rotating barrel that is used to dry materials like minerals, clay, and coal. Materials are fed into the higher end of the sloped barrel where they mix with hot air entering from the lower end. As the barrel rotates, materials move downwards via gravity while mixing with hot air due to lifting vanes inside the barrel. This allows for thorough drying of materials in an efficient manner. The document also provides technical parameters for different rotary dryer models varying in diameter, length, rotation speed, weight, power, and volume.

ROTARY DRYER
Brief introduction
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.
