Working Principle & Process Flow
Our sand dryer adopts advanced imported technology and consists of three concentric cylinders with different diameters, nested and combined in accordance with specific mathematical relationships and structural designs. Based on the principle of thermodynamics, the cylinders are equipped with lifting plates and material guide plates at different angles and intervals. This structure ensures that the materials to be dried move along the spiral direction under gravity, maintaining sufficient residence time and full dispersion inside the cylinders. As a result, the materials undergo thorough heat exchange with the hot airflow from the combustion chamber, eliminating the defects of conventional dryers such as small heat exchange area and low unit volume evaporation intensity caused by air pockets in the cross-section.
The special triple-cylinder structure enables the inner and middle cylinders to be surrounded by the outer cylinder, forming a self-insulating system. The heat emitted from the surfaces of the inner and middle cylinders is reused for the heat exchange of materials in the outer cylinder. Meanwhile, the outer cylinder is located at the low-temperature end of the hot airflow, significantly reducing the heat dissipation area and heat energy loss of the entire equipment. The energy-saving triple-cylinder dryer can fully utilize waste heat, reduce heat dissipation loss, and increase heat exchange area, thereby greatly improving the unit volume evaporation intensity of the dryer. This effectively enhances heat energy utilization rate, lowers energy consumption, and significantly improves the thermal efficiency of the sand dryer.
