The fine crushing teeth refine the material to the target particle size through shearing and collision. The two-layer structure has a clear division of labor and significantly improves the crushing efficiency. The hydraulic dynamic discharge head monitors the material height in the collection tank in real time through the induction contact. When the zinc powder accumulates to the set position, it automatically triggers the induction valve to control the opening and closing of the door for discharge, avoiding the problem of material blockage or excessive crushing caused by the traditional fixed discharge port.

[0026] (2) The bottom surface of the heating channel is provided with a bottom fire gathering plate, which has a certain arc shape, so that the flame reflection effect is better, the heat loss to the surrounding environment is reduced, more heat is concentrated on the heating channel itself, and the heat transfer to the roasting area is enhanced.

[0027] (3) The combination of multi-layer partitions and shelf grooves allows the zinc powder particles to be placed in layers to avoid uneven heating caused by accumulation. At the same time, the arc-shaped guide grooves and gradient openings form a spiral airflow, which enhances the contact efficiency between the hot air and the material and ensures that the reduction reaction is uniform and sufficient. The assembly isolation net adopts a corrugated metal mesh structure, which not only evenly disperses the airflow to ensure the stable operation of the heating resistance wire, but also physically isolates the material to prevent the risk of short circuit. Combined with the layout of the resistance wire for zoned temperature control, it can achieve precise temperature control and extend the life of the equipment. The exhaust waste heat is used to preheat the fresh air and reduce energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS
