Shaking Table

A shaking table, also known as a "separation plate," "mineral processing shaking table," or "gravity shaking table," is a gravity separation device that separates mineral particles based on differences in density and size.

Its core feature is the use of an inclined bed surface with specific grooves. Under the combined action of asymmetrical reciprocating motion and the scouring effect of lateral water flow, different particles in the fed slurry exhibit different movement trajectories, thus forming fan-shaped zones on the bed surface and efficiently separating concentrate, middlings, and tailings.

Core separation principle: Gravity separation

A shaking table is a typical gravity separation device. It does not rely on chemical reactions but utilizes the differences in physical properties between the minerals to be separated and the gangue minerals—primarily density, and secondarily particle size and shape. Denser, smaller particles tend to move in one direction, while less dense, larger particles move in the other.

As a cleaning unit (core role): This is the shaking table's most important role. It is typically located in the later stages of the mineral processing flow, receiving the rough concentrate from roughing equipment such as jigs, spiral concentrators, and centrifugal concentrators. The shaking table's task is to "fine-refine" the rough concentrate, obtaining qualified high-grade concentrate that can be directly sold.

• Flow Example: Raw ore → Crushing → Grinding → Spiral sluice/jig (roughing) → Shaking table (cleaning) → Concentrate.

As a scavenging unit: Sometimes it is also used to process tailings from other gravity separation equipment, recovering valuable minerals, reducing metal loss, and improving the overall recovery rate.
