Overview of Shaking Table
Shaking Table (also known as a concentrator table) is a high-efficiency gravity separation equipment engineered exclusively for fine-grained mineral sorting. As a core product in mineral processing lineups, this shaking table leverages advanced mechanical design and durable materials to separate minerals based on differences in density, particle size, and shape—delivering reliable performance for both small-scale labs and large industrial plants.
Crafted with user needs in mind, the Shaking Table features a tilted reciprocating bed (lined with proprietary wear-resistant polyurethane) and a calibrated water distribution system. It is optimized to process particles ranging from 0.02 to 2 mm, with customizable bed sizes (0.5–8 m²) and motion parameters to match specific ore types—from gold and tungsten to coal and non-metallic minerals. Every unit undergoes strict quality inspection by professional technical teams, ensuring consistent separation accuracy and long-term operational stability.
How Shaking Table Works
The Shaking Table operates on the principle of gravity separation, enhanced by precision engineering that maximizes mineral recovery:
Uniform Feeding: Mineral slurry (ore + water) is evenly distributed onto the upper end of the table’s bed via a specially designed feed chute. Simultaneously, low-pressure washing water (controlled by adjustable nozzles) is sprayed to disperse particles and prevent clumping.
Asymmetric Reciprocating Motion: Driven by a high-torque motor and an exclusive crank mechanism, the bed performs an asymmetric reciprocating movement—slow and long on the forward stroke (to push dense minerals) and fast and short on the backward stroke (to avoid dragging light particles). This motion is key to separating valuable minerals from gangue.
Gravity-Driven Classification: Denser minerals (e.g., gold, tin) are pushed toward the concentrate outlet (lower end of the bed tilt) by the reciprocating motion, while lighter gangue (e.g., quartz) is washed by water toward the tailings outlet (upper end). Medium-density “middlings” (reprocessable material) collect in the middle zone, minimizing resource waste.
Parameter Tuning: Operators can easily adjust stroke length (5–20 mm) and frequency (180–300 strokes/min) via an intuitive control panel. For new ore types, professional technical teams provide recommended settings to ensure optimal separation efficiency from day one.
Core Advantages of Shaking Table
Compared to generic shaking tables or alternative separation technologies (e.g., flotation, magnetic separation), the Shaking Table stands out with unmatched benefits:
Superior Separation Precision: Delivers sharp density-based sorting, producing high-purity concentrates (e.g., 95%+ tin concentrate, 98%+ coarse gold recovery). The asymmetric motion design reduces “middlings” volume by 15–20%, cutting downstream processing costs.
Exceptional Durability: The bed’s polyurethane lining—developed and supplied with proprietary technology—resists wear, corrosion, and particle adhesion, extending service life to 5–8 years (twice that of rubber-lined tables). Key components (crank, bearings) use industry-standard specifications for easy maintenance.
Low Operational Costs: Requires only 1.5–3 kW of power (depending on size) and 2–6 m³ of water per ton of ore—far less than flotation systems. Water-saving spray nozzles further reduce consumption by 10%, lowering long-term operational expenses.
Easy Operation & Maintenance: No specialized training is needed thanks to user-friendly controls. Routine maintenance (e.g., lubricating the crank, cleaning nozzles) takes minimal time, and a global spare parts network ensures quick component replacement.
Strong Versatility: Adaptable to diverse minerals and scenarios—from recovering precious metals in placer mines to upgrading coal in power plants. Compact lab-scale models are also available for ore testing and flowsheet optimization.
Key Applications of Shaking Table
The Shaking Table is trusted by customers worldwide across multiple mineral processing sectors:
Precious Metal Recovery: Ideal for gold, silver, and platinum-group metals (PGMs). The shaking table excels in both artisanal mines (small 0.5–1 m² models) and large industrial operations (3–8 m² beds), delivering high recovery rates even for fine gold particles.
Rare Metal Sorting: Critical for separating tungsten, tin, tantalum, and niobium—minerals where purity directly impacts market value. The polyurethane bed prevents cross-contamination, ensuring concentrates meet refining standards.
Coal Beneficiation: Removes pyrite and sulfur-bearing impurities to improve coal quality and reduce environmental emissions. The shaking table is designed for low water usage (3–5 m³/t coal), aligning with sustainable production goals.
Non-Metallic Mineral Processing: Separates barite (for oil drilling), fluorite (for metallurgy), and magnesite (for construction) from gangue. Custom bed widths (1.2–3.6 m) are available to match throughput requirements of 5–100 t/h.
Lab & R&D: Compact models are used in mineral labs to analyze ore grade, test separation efficiency, and optimize production flowsheets—providing data support for large-scale project planning.
