Working Principle
  After the wet material is put into the dryer at one end of the dryer, the material is evenly distributed and dispersed in the dryer, and the material is evenly distributed and dispersed in the dryer, and it is fully contacted with the hot air of the countercurrent (counter current), which speeds the heat transfer and passes to the driving force. During the drying process, the material can be adjusted and moved to another part of the star unloading valve of the dryer to discharge the finished product under the action of the plate with inclination and hot air flow.

Characteristics
◎The rotary dryer has a high degree of mechanization and large production capacity.

◎The fluid has low resistance and low function through the cylinder.
◎The adaptability of the material is relatively strong.
◎The operation is stable, the operation cost is low, and the drying uniformity of the product is good.
Material to be dried
◎Large particles in chemical, mining, metallurgical and other industries, the proportion of heavy materials drying, such as mining, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.
 ◎Drying of powders and granular materials with special requirements, such as HP foaming agent, distiller's residue, light calcium carbonate, activated clay, magnetic powder, graphite and residue.
◎Materials that require low temperature drying and require large quantities of continuous drying.
