As one of the most classic and reliable gravity separation machines, the mining shaking table is widely used for the fine classification and separation of gold, tungsten, tin, lead, zinc, manganese, chrome, and other metallic and non-metallic minerals. Featuring high concentration ratio, precise sorting performance, low energy consumption, and simple operation, it has become essential equipment for small and medium-sized mineral processing plants worldwide.
1. Working Principle of Shaking Table
The shaking table separates minerals relying on the density difference of mineral particles, differential reciprocating motion of the table surface, and transverse water flow. The whole separation process is pure physical gravity sorting without chemical reagents.
Step 1: Particle stratification
The pulp is evenly fed to the inclined table surface. With the longitudinal asymmetric reciprocating movement and transverse thin water flow, mineral particles are fully loosened and layered. High-density mineral particles sink to the bottom layer, while low-density gangue particles float on the upper layer.
Step 2: Zonal separation
The differential motion of the table pushes high-density valuable minerals toward the concentrate outlet. Meanwhile, the transverse water flow washes low-density waste rock and impurities toward the tailing outlet.
Step 3: Final discharging
Minerals with different densities form an orderly fan-shaped distribution on the table surface. Concentrate, middlings, and tailings can be discharged separately in one single operation, realizing efficient and precise mineral separation.
2. Main Equipment Structure
The shaking table adopts a simple and durable integrated structure, mainly composed of six core parts: transmission head, table surface, frame, feeding tank, water tank, and slope adjusting device, with low failure rate and easy daily maintenance.
-
Transmission Head: The core power component that drives the asymmetric reciprocating movement of the table. The stroke and frequency are adjustable to adapt to different mineral sizes.
-
Table Surface: The working sorting surface with longitudinal riffles to prevent mineral loss. The transverse inclination angle can be adjusted freely.
-
Sturdy Frame: High-strength steel structure ensures stable operation, shock resistance, and long service life.
-
Feeding & Water Tank: Realize uniform feeding and water supply to ensure consistent sorting effect.
-
Slope Adjuster: Flexible adjustment of longitudinal and transverse angles to match various mineral processing requirements.
