1. PAINPOINT DRIVEN OPENING

Are you managing escalating costs and unpredictable downtime in your gravity separation circuit? Inconsistent feed rates, inefficient water management, and high maintenance cycles on your concentration tables directly impact your bottom line. These operational challenges manifest as lost fine gold, increased reagent consumption, and laborintensive cleanup procedures. How do you achieve consistent, highgrade concentrates without sacrificing throughput or requiring constant operator intervention? The solution lies in optimizing a core component of your recovery plant: the shaking table.

2. PRODUCT OVERVIEW

Our Wilfleystyle mineral concentrating shaking table is engineered for the efficient separation of heavy mineral particles, specifically for gold recovery in both alluvial and hard rock processing plants. It operates on the principle of differential particle density and size across a riffled deck subjected to a reciprocating motion.

Operational Workflow:
1. Slurry Introduction: A controlled slurry feed (typically 2030% solids) is introduced at the head of the table.
2. Stratification & Separation: The reciprocating motion and wash water flow stratify particles; denser minerals (e.g., gold) settle into the riffles, while lighter gangue material is carried across and off the table.
3. Concentrate Collection: Highgrade concentrate is channeled to specific collection points along the side of the deck, with middlings and tails directed to separate outlets.

Application Scope: Ideal for final concentration of gold from cyclone underflow, centrifugal concentrator tailings, or as a primary concentrator for coarse liberated gold. Effective on particle sizes typically between 100 mesh and 1 mm.

Limitations: Not suitable for slimes (ultrafine particles below ~400 mesh). Performance is dependent on consistent feed density and particle size distribution. Requires a stable, level installation foundation.

3. CORE FEATURES

Precision Deck Motion | Technical Basis: Balanced headmotion mechanism with adjustable stroke length | Operational Benefit: Delivers optimal particle stratification and transport for a wider range of feed materials | ROI Impact: Improves recovery rates by 38% on marginal ores compared to worn or poorly tuned mechanisms.

Modular Riffle System | Technical Basis: Interchangeable rubber riffle mats with varied patterns | Operational Benefit: Allows rapid configuration change for different mineral suites or particle sizes, minimizing downtime | ROI Impact: Reduces changeover time by up to 70% versus bonded wooden decks.

Integrated Water Distribution | Technical Basis: Laminarflow wash water channels with independent bank controls | Operational Benefit: Provides even, controllable water flow across entire deck width for sharp separation bands | ROI Impact: Cuts process water consumption by an estimated 1525% through targeted application.

LowMaintenance Drive Assembly | Technical Basis: Enclosed gearbox drive with oil bath lubrication and standard Vbelt connection | Operational Benefit: Eliminates daily greasing points, reduces failure risk from slurry contamination | ROI Impact: Lowers annual bearing and drive maintenance costs by approximately 40%.

Reinforced Structural Frame | Technical Basis: Fabricated steel frame with vibrationdampening crossbracing | Operational Benefit: Maintains critical deck levelness under load, prevents harmonic vibration that disrupts separation | ROI Impact: Extends structural service life, protects against costly foundational stress damage.

6. APPLICATION SCENARIOS

[Hard Rock Gold Mill – Flotation Tailings Cleanup] Challenge: A milling operation was losing fine liberated gold to flotation tailings due to inefficient scavenging. Existing tabling was hampered by inconsistent feed from cyclones.

[Solution]: Two ST4422 shaking tables were installed in parallel to process cyclone underflow. Modular riffles were configured for fine gold recovery (~100 mesh).

[Results]: Field data shows an additional 0.8 g/ton gold recovered from tailings stream, generating a payback period of under nine months based on throughput.

[Alluvial / Placer Operation – Primary Concentration] Challenge: A placer site needed a robust primary concentrator that could handle variable clay content without constant clogging or operator adjustment.

[Solution]: Implementation of shaking tables with enhanced wash water controls allowed operators to quickly adapt to changing feed conditions.

[Results]: Plant availability increased by 12%, and concentrate grade improved by 22%, significantly reducing downstream smelting charges.
