Rotary dryer is the most common application of mining machine and it is most widely used drying equipment .And it is suitable for drying metallic and non-metallicCharcoal/ coal industry.including charcoal briquetting production line. magnetic heavy floating concentrate, cement industry clay ,Many other drying applications.
Working principle of rotary dryer 1. Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator. 2. Materials enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, and then materials and hot air mix together. 3. Materials go to the lower side by gravity when the barrel is rotating. 4. Lifters on the inner side of barrel lift materials up and down in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of rotary dryer.
