Rotary Dryer

The advantages of Rotary dryer:
  High dry capacity, smooth rotation, low energy consumption, easy operation, high output and so on.
  Rotary dryer Instruction:
  Dryer also named as Drying Machine and Rotary Dryer. Dryer is mainly consist of rotary body, raw material feeding plate, driving and supporting device, etc.Rotary dryer is widely used for drying slag, clay, limestone and other materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control dryer temperature. The temperature change of dryer's feeding end can be indicated by the thermometer to control the inner dryer temperature ( generally 250-350°C).
  Rotary dryer Structure:
  Rotary dryer machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.
  Rotary dryer working principle:
  Rotary dryer adopts direct flow type of heating with heat source from firing unit. The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the dryer is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering .Its principle of operation: the raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dried.
