How to Choose the Right Shaking Table for Your Mineral Processing Plant – A Buyer’s Guide
This procurement Q&A guide covers key factors when buying a shaking table for mineral separation, including working principle, technical parameters, model comparison, and cost considerations.
1. What is a Shaking Table and How Does It Work?
A shaking table is a gravity separation equipment widely used in the beneficiation of fine-grained minerals such as tungsten, tin, tantalum, niobium, gold, and other precious metals. It separates materials based on density and particle size by combining a reciprocating motion with water film flow. The table surface has riffles that allow heavy particles to be captured and discharged along the concentrate end, while light particles are washed away.
2. Key Technical Parameters to Consider
When selecting a shaking table for your plant, the following parameters must be evaluated:
| Parameter | Typical Values / Options | Remarks |
|---|---|---|
| Table Type | 6-S, LY, XZY, YC, etc. | 6-S is the most common for coarse feed; LY for fine sand |
| Feeding Size | 0.074 – 2 mm (coarse), 0.037 – 0.074 mm (fine) | Overly fine or coarse particles reduce recovery |
| Capacity | 0.5 – 1.5 t/h per table (coarse), 0.1 – 0.5 t/h (fine) | Depends on feed density and particle size |
| Stroke Length | 10 – 30 mm (adjustable) | Shorter stroke for fine separation |
| Stroke Frequency | 180 – 300 strokes/min | Higher frequency increases separation intensity |
| Water Flow Rate | 10 – 50 L/min | Adjustable based on washing requirement |
| Table Deck Slope | 0 – 10° (transverse), 0 – 2° (longitudinal) | Adjustable to control product grade |
| Motor Power | 1.1 – 2.2 kW | Depends on model |
| Deck Material | Fiberglass, wood, metal, or rubber | Fiberglass is durable and corrosion resistant |
3. Common Models & Their Best Applications
| Model | Deck Size (L×W, mm) | Best For | Feed Size (mm) | Capacity (t/h) |
|---|---|---|---|---|
| 6-S 7.5㎡ | 4500×1850 | Coarse tungsten/tin | 0.074 – 2 | 1.0 – 1.5 |
| 6-S 4.08㎡ | 3000×1620 | Medium sand | 0.074 – 1 | 0.5 – 1.0 |
| LY 2100×1050 | 2100×1050 | Fine sand & slime | 0.037 – 0.074 | 0.1 – 0.5 |
| XZY 2600×1300 | 2600×1300 | Gold, tantalum, niobium | 0.037 – 0.5 | 0.2 – 0.6 |
4. Procurement Checklist – 5 Critical Questions to Ask Your Supplier
Q1: What is the maximum feeding moisture content the table can handle?
A: Most shaking tables require feed with moisture around 25–40% by weight. Higher moisture may cause clogging.
Q2: Can the stroke length and frequency be adjusted on site?
A: Yes, a good supplier provides easy stroke adjustment via eccentric wheel and frequency via pulley change or VFD.
Q3: What type of deck surface is recommended for my ore?
A: For abrasive ores like tin, fiberglass deck with rubber lining is preferred. For gold, a smooth rubber deck helps recover fine particles.
Q4: How long is the typical deck lifespan under 8-hour daily operation?
A: Fiberglass decks last 3–5 years; wood decks need replacement every 1–2 years.
Q5: Are spare parts (riffle bars, eccentric shaft, drive belt) readily available?
A: Ensure the supplier stocks common spares or offers a list of interchangeable parts.
5. Cost vs. Performance – Making a Wise Investment
Shaking tables are relatively low-cost compared to spiral concentrators or centrifugal concentrators, but their efficiency heavily depends on operator skill and feed preparation. Always request a laboratory-scale test report from the manufacturer using a representative ore sample before placing a large order. Table prices vary from $3,000 to $15,000 depending on size and deck material. For multi-table setups, consider the layout and trough design to minimize floor space.
6. Final Tips for First-Time Buyers
- Always look for a 12-month warranty and after-sales technical support.
- Check if the supplier provides free on-site installation guidance or training.
- Request a manual with detailed maintenance schedules for drives and bearings.
- Verify the table’s compliance with ISO or CE standards if exporting to your region.
By evaluating these technical parameters and asking the right questions, you can select a shaking table that delivers consistent recovery and low operating costs for decades.
