Introduction
When it comes to recovering fine heavy minerals, shaking tables are one of the most precise gravity separation devices available. They use a combination of riffled deck motion, water flow, and gravity to create perfect stratification of minerals by specific gravity. China has become a global leader in manufacturing high-efficiency shaking tables for recovering gold, tin, tungsten, tantalum, chromite, and other valuable minerals from fine-grained ores and tailings.
If you need reliable, cost-effective, and high-precision gravity separation solutions for fine minerals, this guide covers everything you need to know about China’s shaking table industry.
I. Understanding Shaking Tables
What is a Shaking Table?
A shaking table, also known as a gravity shaking table or wilfley table, is a gravity separation device that uses a combination of reciprocating deck motion, water flow, and riffles to separate fine minerals based on their specific gravity. It is widely used for recovering fine particles of gold, tin, tungsten, tantalum, chromite, and other heavy minerals from 0.037mm to 2mm size range.
Core Working Principle
Shaking tables operate on three key actions working together:
- Deck Motion: The table deck moves back and forth asymmetrically (slow forward stroke, fast return stroke), carrying material toward the discharge end while allowing stratification.
- Water Flow: A stream of water flows along the deck from the feed side, washing lighter particles downward while heavy particles are held back by riffles.
- Riffle Action: Riffles (grooves or ridges) on the deck create turbulence and capture heavy minerals, allowing them to settle and move along the deck.
The result is three distinct product streams: concentrate (heavy minerals), middlings (mixed particles), and tailings (light waste).
Key Technical Features of Chinese Shaking Tables
- High Separation Precision: Capable of separating minerals with specific gravity differences as small as 0.3
- Fine Particle Recovery: Effective recovery down to 0.037mm (37 microns)
- Adjustable Operation: Stroke length, stroke frequency, water flow rate, and deck tilt angle can be adjusted for optimal performance
- Multiple Deck Options: Single, double, triple, and 4-deck configurations available for different capacity requirements
- Durable Construction: Fiberglass-reinforced plastic decks with epoxy surface for long service life
- Low Operating Cost: No chemicals required, low power consumption, minimal maintenance

VI. Why Choose Chinese Shaking Tables?
6.1 High Separation Precision
Chinese shaking tables are designed to achieve sharp separation even when specific gravity differences between target mineral and gangue are small. The adjustable stroke, frequency, water flow, and deck tilt allow operators to fine-tune performance for specific ores.
6.2 Fine Particle Recovery
While many gravity devices lose efficiency below 0.1mm, Chinese shaking tables effectively recover down to 0.037mm (37 microns). This makes them ideal for recovering fine gold, tin, and tungsten that would otherwise be lost to tailings.
6.3 Cost-Effective
Shaking tables have no moving parts in contact with the slurry except the deck drive mechanism, which means low maintenance costs. They use no chemicals, only water and gravity, making them environmentally friendly and inexpensive to operate.
6.4 Durable Construction
Modern Chinese shaking tables feature fiberglass-reinforced plastic decks with epoxy surfaces that resist wear and corrosion. The deck drive mechanisms are built for continuous operation with minimal maintenance.
6.5 Multiple Configurations
Chinese manufacturers offer single, double, triple, and 4-deck shaking tables to match capacity requirements from 0.5 to 8 tons per hour per machine. Laboratory-scale tables are also available for test work.
