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.

Widely used in building materials , metallurgy , chemical industry, cement industry bake dry limestone slag , fly ash , coal dust, slag, clay and other materials.

1. The dryer is of strong overload capacity resistance, large process load, low fuel consumption, and low cost.
2. It adopts direct flow drying method. The gas fume and the material go to the dryer from the same side. By using the hyper thermal gas fume, the evaporation strength is very high. With the low outlet temperature, the heat efficiency is very high.
3. The operating parameter can be changed according to different materials. So that the material can form a stable fabric curtain and achieve fully heat exchange.
4. The new type feeding and discharging device solve the problem of feeding jam, discontinuous and uneven feeding, and returning charge which lighten the load of dedusting system.
5. The new inner structure strengthens the cleaning and heat conduction of the dispersed material, and eliminates the bonding in the inner drum wall. The adaptability to the material moisture and stickiness is stronger.
