working principle
  The hot air enters the bottom of the dryer tangentially, and is driven by the agitator to form a powerful rotating wind field. Paste material enters the dryer from the screw feeder. Under the strong action of the high-speed rotating stirring blade, the material is dispersed under the action of impact, friction and shearing force. The block material is quickly crushed, fully contacted with hot air, and heated. ,dry. The dried material after dehydration rises with the hot air flow, the grading ring traps large particles, and the small particles are discharged from the center of the ring to the outside of the dryer and recovered by the cyclone separator and dust collector. The incomplete or large materials are thrown to the wall by centrifugal force. , And fall to the bottom to be crushed and dried.

Note: 1. The amount of water evaporation is the water that evaporates per hour when the inlet air temperature is 180°C and the outlet air temperature is 80°C.
  2. In addition to the above models, special designs can be made for users,
  3. The above installed capacity is a standard package, and the power package can be significantly reduced according to different materials.
