The working principle is that when the temperature at the bottom of the dryer reaches 400 ℃ -800 ℃, the material is fed from the feeding port by the elevator, and under the action of gravity, it is dispersed, crushed, and the dispersion device is evenly distributed inside the dryer to flow (ensuring the heat exchange effect of the material inside the dryer). Hot gas is generated by the lower hot air furnace and moves from bottom to top, coming into contact with the material. Through various means such as heat conduction, convection, and radiation, heat is transferred to the material, causing the temperature of the material to continuously rise and the moisture to evaporate. Finally, the material that meets the moisture requirements is discharged from the lower outlet, and the gas with water vapor is extracted from the chimney by the fan. The scope of application of the rotary dryer has made significant breakthroughs and innovations on the basis of the traditional single cylinder rotary dryer structure. From the perspective of drying mechanism, the exchange between materials and hot air flow is more comprehensive, scientific and reasonable, and all thermal indicators have reached a leading level. Suitable for drying various raw materials such as clay, gypsum, coal, slag, coal gangue, mixtures, dry mixed mortar, yellow sand, iron powder, etc. It is also suitable for drying raw materials in the production of phosphate and composite fertilizers, as well as various loose materials in industries such as metallurgy and chemical engineering
