Before the birth of sand rotary dryer, if people want to dry sand material, the common way is natural air drying on a broad field. However, if it is rainy day, the drying efficiency would be severely influenced. Along with the scientific and technological development, we successfully invent an amazing machine, called sand dryer machine. Even drying is of great importance for improving the drying efficiency of rotary sand dryer. The following content will discuss about the improvement techniques on even drying.

In order to realize even drying in sand rotary dryer, we can increase the contacting space and prolong the contacting time between sand materials and hot air in rotary drum based on axial units. At the same time, we can transform the lifting boards to increase the distribution area in cross section of rotary drum. Also, we can lengthen the rotary drum.

As long as we improve the flow rate of hot air, the heat transfer coefficient and drying speed can increase directly. Meanwhile, timely changes of hot air can be realized, which is good for outer diffusion. However, the improvement of flow rate would decrease the stay time of hot air in rotary drum, seriously influence the thermal efficiency and cause the waste of heat energy.
