Part two: Brief introduction of rotary drum dryer
Rotary drum dryer is mainly applicable for drying materials in agricultural industries as well as in the fields of
cemet, contruction,building materials,chemicals, food, light industry,medicine and mining,etc.
It can be used to dry material materials with specified moisture and size.
Feeding and discharging unit is installed with thermocouple to control drier temperature.
The temperature change of drier's feeding end can be indicated by the thermometer to control the inner drier
temperature(generally 250-350°C).
Part three: The working principle of rotary drum dryer
The raw materials are sent to hopper of rotary drum 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.
