Excavator pour the materials on grizzly bar to screening,gravel rinsed by high pressure water then discharge form the hindside, material particle size can reach 40 cm. The smaller particles fall to the second floor screen for separation, after sifting through the second layer, the sand water mixture flows into two separate adjustable sluice for gold enrichment.This sluice can be adjusted front and rear angle, left and right balance to achieve maximum recovery rate by adapting to different terrain and operating conditions.
VGM-300

|---|---|
The VGM-300 Portable Vibrating Sieve redefines efficiency in placer gold mining with its integration of hydraulic-driven vibration and adjustable screening technology, designed to maximize gold recovery in challenging conditions. Engineered to handle 50-150 tons of material per hour, this industrial-grade sieve excels at separating gold from clay, gravel, and coarse sediment—even in high-clay environments where traditional sieves struggle. Its modular design allows quick disassembly into transportable components (each under 2 tons), making it feasible to deploy in remote sites accessible only by truck or trailer. Complemented by high-pressure water jets (50 PSI), the system breaks up compacted clay lumps and washes sediment clinging to gold particles, ensuring thorough liberation before separation. The hydraulic motor reduces mechanical failures by 30% compared to traditional electric motors, while lowering fuel consumption through variable speed control.
Parameter | Value |
Screen Size | 1.2m x 3m (adjustable mesh: 5-20mm) |
Power Source | Hydraulic Motor (380V/50Hz) |
Processing Capacity | 50-150 tons/hour |
Weight | 10 tons |
Water Consumption | 500 L/min |
Mobility | Wheeled Trailer Mount |
Hydraulic Vibration Technology: Generates 3,000 RPM oscillations that agitate material evenly across the screen surface, reducing clogging by 40% compared to static sieves and enhancing gold separation efficiency by 30% through consistent particle stratification.
Adjustable Screen Mesh: Interchangeable 5-20mm screens enable precise targeting of gold sizes—5mm mesh captures flour gold and small flakes, while 20mm mesh handles larger nuggets and coarse sediment, adapting to varying deposit characteristics.
Self-Contained Processing System: Integrates a diesel-powered water pump (eliminating reliance on external water sources) and a built-in sluice box, creating an all-in-one solution that reduces setup time by 50% versus modular systems.
Low Maintenance Design: Replaceable polyurethane liners reduce wear from abrasive gravel, extending screen lifespan by 30% compared to steel liners, while quick-release fasteners allow liner replacement in under 1 hour.
Commercial Mining Operations: Processes bulk alluvial deposits in riverbeds, floodplains, and ancient river channels, where gold accumulates in layers of gravel, sand, and clay.
Construction Waste Recycling: Recovers gold from excavated soil in urban development projects, transforming construction byproducts into valuable mineral resources and reducing landfill waste.
Mining Contractors: Delivers reliable performance for short-term projects, including seasonal gold rushes, site evaluations, and emergency recovery operations requiring high throughput.
Q: Can it handle both wet clay-rich sediments and dry gravel?
A: Yes, the high-pressure water jets (50 PSI) effectively break down and wash clay-rich wet materials, while the vibration system agitates dry gravel to separate gold without requiring additional moisture.
Q: What’s the smallest gold particle size it can reliably recover?
A: When equipped with the 5mm mesh screen, the sieve captures particles as small as 0.075 mm, ensuring even fine flour gold is retained for downstream processing.
Q: What maintenance schedule is recommended for optimal performance?
A: Under heavy use (10+ hours daily), screens should be inspected weekly; polyurethane liners typically last 2-3 months before needing replacement. The hydraulic system requires oil changes every 500 operating hours to prevent wear.
