rotary dryer--key equipment for fertilizer industry plant

rotary dryer

Wet material is loaded from one head of the rotary drum dryer, and then it is stirred by the bafflers that is uniformly distributed in the barrel. Material is uniformly distributed and dispersed in the dryer, fully contact the hot air of parallel (or counter) flow, so the drying process is expedited, and the impulsion power of media transfer is enhanced. During the drying process, material is under the effect of angled baffler and hot air, moves to the star shape unloader that is at the other head of the drver.

Applications of rotary dryer

Applicable for drying big particles, heavy particles in chemical, mining, and metallurgy, such as mining area, cinder of blast furnace, coal, powder of metal, phosphate fertilizer and thiamine.https://www.hnfertilizermachine.com/
For drying the powder or particles with special requirements, such as HP foaming blowing agent, residule of alcohol, light calcium carbonate, active clay, magnetic powder, graphite, and residue of medicine. For materials to be dried under low temperature and large lot continuous production

Working principle of rotary drier

rotary drum dryer principle is that 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 airflow and changed into vapour to be discharged into the atmosphere. Then the materials would be dried.it rotary dryer is used together with npk compound fertilizer granulation equipment to make chemical fertilizer and disc granulator to make organic granules for crops
