As a core gravity separation equipment, Jiangxi Mingxin Shaking Table achieves accurate sorting by leveraging the synergy of mechanical vibration + transverse water flow and utilizing the differences in material specific gravity and particle size. It is widely suitable for the recovery and sorting of fine-grained materials such as waste lithium batteries, circuit boards, and metal slag, with no chemical agents involved throughout the process. Green and efficient, it is a practical choice for renewable resource recovery and mineral separation.
The sorting core of Mingxin Shaking Table lies in enabling materials with different characteristics to complete the precise separation of stratification - migration - zoning on the bed surface. Slurry prepared to an appropriate concentration enters from the feeding trough at the high end of the bed surface. Driven by the transmission mechanism, the bed surface performs an asymmetric reciprocating motion, and at the same time, the transverse flushing tank continuously injects water to form a thin water film. Under the dual action of vibration and water flow, particles in the slurry are quickly loosened and stratified: valuable particles with high specific gravity such as metals settle to the bottom layer of the bed surface and are in close contact with it; light non-metallic particles with low specific gravity float on the upper layer.
The asymmetric vibration of the bed surface provides longitudinal power for the heavy particles at the bottom layer, making them move slowly along the bed surface to the concentrate end on the uphill side; the light particles on the upper layer are dominated by the scouring force of the transverse water flow and discharge to the tailings end along the transverse inclination of the bed surface. Materials with different specific gravity and particle size form a clear fan-shaped zoning on the bed surface, and concentrate, middling and tailings are accurately discharged from different outlets. Valuable materials can be enriched and impurities separated in a single operation.
The bed surface of Mingxin Shaking Table is equipped with special wear-resistant riffles, which can effectively prevent the transverse sliding of heavy particles and further improve the sorting accuracy. The bed slope, stroke frequency and flushing water volume can be flexibly adjusted, which can be adapted to the characteristics of different materials such as lithium battery powder, circuit board crushed material and metal ore sand, taking into account both sorting efficiency and enrichment ratio. It enables the efficient recovery of valuable resources in waste materials and provides stable and reliable sorting support for the renewable resource recovery production line.
