ONE:Basic Definition
Gold Shaking Table
Gold shaker table (also called shaking table, gold concentrating table) is a mainstream wet gravity separation equipment for recovering fine gold, widely used in alluvial gold, rock gold, tin, tungsten, chrome, silver and other heavy mineral beneficiation.
TWO:Working Principle
Separation relies on the density gap between gold (high specific gravity ~19.3) and gangue (quartz ~2.65), driven by three combined forces：
Longitudinal reciprocating jerk motion
The head mechanism delivers fast backward stroke + slow forward stroke; inertia pushes heavy gold particles forward toward the concentrate outlet.
Transverse flushing water flow
Thin water film flows across the inclined deck perpendicularly to vibration, washing light waste sand sideways to tailings discharge.
Stratification by riffles
Parallel raised riffle grooves on the deck trap dense gold at the bottom of grooves; light gangue floats on top and gets swept away by cross water.
Result: Materials divide into 3 products in fan zones on the table:
Concentrate (high-purity gold)
Middlings (mixed ore for reprocessing)
Tailings (worthless gangue).
THREE:Core Structure
Table deck：Fiberglass / rubber coated surface with customized riffle patterns; inclined angle adjustable
Head motion drive unit：Eccentric crank + motor, controls stroke length & vibration frequency
Support frame & rockers：Heavy steel base for stable shaking
Feed box & water distribution trough：Evenly supply ore slurry and flushing water
Angle adjustment assembly：Tilt angle fine-tuning for different grain sizes.
FOUR:Main Classification & Application
1. By feed particle size
Coarse sand table: Feed 0.5–2 mm (coarse gold grains)
Fine sand table: Feed 0.074–0.5 mm (fine gold powder)
Slime table: Feed 0.02–0.074 mm (superfine gold dust)
2. By scale
Industrial large table: Capacity 0.5–6 t/h, for large gold wash plants
Mini portable table: 20–200 kg/h, small-scale mining, lab test
Multi-layer shaking table: Double/triple deck, save floor space, boost output.
Key Technical Parameters (Standard 6-S Model)
Feeding density: 15%–30% solid slurry
Vibration frequency: 400–1200 strokes/min (low freq for coarse gold, high for fine gold)
Stroke: 8–18 mm
Deck tilt angle: 0°–10° adjustable
Power: 1.1–3 kW
Daily throughput: 20–60 tons raw ore
