The working principle of quartz sand dryer

  Quartz sand dryer is a new type of drying equipment developed by Zhengzhou Jiutian. It has the characteristics of reliable operation, large production volume, high work efficiency and low overall energy consumption. When the initial moisture content of sand is 20%, the final moisture can be dried below 0.5-1%. On the basis of saving production costs and improving economic benefits, it greatly meets the needs of large sand manufacturers.

  Working principle:

  The material enters the inner layer of the dryer from the feeding device to realize downstream drying. The material is continuously picked up and scattered under the copying plate of the inner layer to realize heat exchange, and the material moves to the other end of the inner layer and enters the middle layer. , countercurrent drying is carried out, and it is continuously and repeatedly raised in the middle layer, in a way of advancing two steps and one step back. The material in the middle layer not only fully absorbs the heat emitted by the inner layer drum, but also absorbs the heat of the middle layer drum. dry state. The materials that achieve the drying effect are quickly discharged under the action of hot air, and the materials that do not achieve the drying effect cannot travel quickly due to their own weight. The energy-saving sand dryer produced by the company can make full use of waste heat, reduce heat dissipation loss, increase heat exchange area, and greatly improve the evaporation intensity per unit volume of the dryer, thereby effectively improving the utilization rate of heat energy, reducing energy consumption, making thermal efficiency has been greatly improved.
