How a Shaking Table Works
A shaking table separates minerals purely by their specific gravity difference — no chemicals, no heat. Three simultaneous forces act on the slurry to stratify and sort particles into a fan-shaped discharge pattern.
01
Asymmetric Vibration
The drive unit creates a slow forward stroke and fast return stroke. Heavy particles are carried updip by inertia on the forward stroke; lighter particles are left behind on the fast return.
02
Transverse Water Flow
Wash water flows across the deck from the launder side toward the tailings side. Lighter, smaller particles are swept sideways faster; heavy particles resist the water and travel further up the deck.
03
Fan-Shaped Discharge
The combined action stratifies particles into a fan: high-SG concentrate at the top, middlings in the middle, and tailings at the bottom. Splitters divide each zone for separate collection.
Why no chemicals are needed
Shaking tables exploit only the physical property of specific gravity — the same principle as gold panning. This makes them environmentally clean, low-cost to operate, and suitable for small-to-medium scale artisanal and commercial operations worldwide.

Recoverable Minerals
Any mineral with SG significantly higher than gangue (quartz SG 2.65) can be recovered. A minimum SG difference of 1.0 is recommended for effective separation.
Gold
SG 19.3Alluvial and hard-rock fine gold; high SG difference enables excellent recovery
Tungsten (Wolframite)
SG 7.1–7.5Primary beneficiation method; concentrates up to 65% WO₃ in one pass
Tin (Cassiterite)
SG 6.8–7.1Fine cassiterite recovery down to 0.1 mm; industry standard for tin dressing
Tantalum & Niobium
SG 5.6–8.1Rare metal concentration; often combined with magnetic separation
Chromite
SG 4.5–4.8Pre-concentration before smelting; removes gangue silicates efficiently
Iron Ore (Fine)
SG 4.9–5.3Fine hematite and magnetite slimes recovery; supplement to magnetic separation
Main Components
Six key components — each adjustable during operation to optimise recovery and grade for your specific ore.
Deck Surface
Fiberglass or rubber-lined deck with longitudinal riffles (grooves). Riffles trap heavy minerals while lighter particles are swept transversely by wash water. Spacing and height are optimised per feed size.
Drive Mechanism
Eccentric or vibrating drive unit creates asymmetric reciprocating motion — a slow forward stroke and fast return. The resulting differential inertia moves heavy particles updip along the riffles.
Stroke Adjuster
Adjusts stroke amplitude (8–36 mm) while running. Longer stroke moves material faster and suits coarser feed; shorter stroke improves fine-particle separation.
Tilt Adjuster
Controls the deck's cross-slope (0–5°). Steeper slope increases water velocity and suits faster-settling heavy particles; shallower slope suits fine slimes.
Feed Box & Splitter
Distributes feed slurry evenly across the full deck width. Splitters at the discharge end separate concentrate, middlings, and tailings zones for independent collection.
Wash Water Launder
Distributes clean wash water across the full deck width. Water flow rate is the most critical operating variable for recovery and grade.
Selection Guide
Four key parameters determine the right shaking table configuration for your ore.
01
Determine Feed Particle Size
The 6-S(4500) standard deck handles 0.074–2 mm. For feed below 0.074 mm (slime), specify the LS-4500 slime deck variant with finer riffles and lower wash water velocity.
02
Estimate Required Capacity
Shaking tables are low-capacity precision separators — typical range is 0.1–2.5 t/h per unit. Large operations run multiple tables in parallel. Calculate total feed tonnage and divide by model capacity.
03
Confirm Specific Gravity Difference
Shaking tables rely on SG difference between target mineral and gangue. Minimum SG difference for effective separation is 1.0. The larger the difference (e.g. gold SG 19.3 vs quartz SG 2.65), the higher the recovery.
04
Plan Concentrate Handling
Shaking tables produce a continuous fan of concentrates, middlings, and tailings. Plan collection launders and splitter positions before installation. Multiple passes (re-tabling) improve final grade.

Maintenance Schedule
Shaking tables are low-maintenance, but riffle wear and wash water consistency are critical for maintaining recovery rate.
Every Shift
- Check deck surface for worn or missing riffles — replace immediately to avoid recovery loss
- Verify wash water flow rate is steady; fluctuations cause grade/recovery swings
- Inspect stroke length with a ruler; adjust if outside target range
- Clean feed distributor of coarse material build-up
Weekly
- Lubricate eccentric drive bearing per maker's spec (typically grease, monthly)
- Check all deck fastening bolts for looseness due to vibration
- Inspect splitter positions and re-set if concentrate/tailing boundary has shifted
- Clean rubber deck surface with soft brush — do not use metal scrapers
Monthly
- Measure riffle height at multiple points; replace deck if riffles are below 50% original height
- Inspect drive spring or rubber mounting for fatigue cracks
- Check motor current draw — rising current with no load change indicates drive wear
- Re-calibrate tilt angle with a digital level

Shaking Table FAQ
Short answers to common procurement questions before requesting quotation.
What particle size range works best on a shaking table?
Shaking tables are strongest in fine to medium particle ranges where specific-gravity contrast is clear. Very fine slime feeds may require dedicated table configuration.
How much throughput can one table handle?
Single-table capacity is relatively low and depends on ore type and feed size. Larger projects usually deploy multiple tables in parallel.
What controls the grade and recovery balance?
Stroke, deck slope, wash-water flow, and splitter position are the main tuning variables. Small adjustments can significantly change separation results.
Is shaking table suitable for gold and tin recovery?
Yes. It is a standard gravity concentration unit for gold, tin, tungsten, and other high-specific-gravity minerals in appropriate size ranges.
