Principle of working 

The dry-mix mortar dryer utilizes advanced foreign technology introduced by Zhengzhou DMG Mining Machinery. It consists of three concentric cylinders of varying diameters, interlocked and arranged according to a specific mathematical relationship and structural form.

Based on the principle of thermal energy, the cylinders are equipped with lifting and guiding plates at varying angles and spacings. This structure ensures that the material being dried moves along the spiral path under the influence of gravity, maintaining sufficient residence time and dispersion within the cylinders. This allows for sufficient heat exchange between the material and the hot air flow from the combustion chamber, eliminating the drawbacks of conventional drying equipment, which often result from wind tunnels in their cross-sections, resulting in a small heat exchange area and low evaporation intensity per unit volume. The unique three-cylinder structure surrounds the inner and middle cylinders within the outer cylinder, creating a self-insulating system. Heat dissipated from the surfaces of the inner and middle cylinders participates in the heat exchange with the material in the outer cylinder. Since the outer cylinder is at the cooler end of the hot air flow, the heat dissipation area and heat energy loss are significantly reduced. The energy-saving three-drum dryer can make full use of waste heat, reduce heat loss, increase heat exchange area, and greatly improve the evaporation intensity per unit volume of the dryer, thereby effectively improving the utilization rate of thermal energy, reducing energy consumption, and significantly improving thermal efficiency.
