Automatic Discharge Gold Concentrator Gold Ore Processing Equipment

Product Specification

Automatic discharge gold concentrator

1.Product Introduction Gold Ore Processing Equipment

Designed for continuous, unattended gold enrichment, this system integrates a PLC (Programmable Logic Controller) system with pneumatic or electric backwash valves. It automatically triggers high-pressure water backwashing every 1–4 hours of operation, thoroughly flushing and collecting enriched gold concentrate from the rotor grooves without manual intervention or downtime. Featuring a robust Q235 carbon steel frame and a stainless steel inner cone, its critical components boast a service life exceeding 8,000 hours. Throughput capacities range from 0.6 to 80 t/h, making it ideal for both stationary plants and mobile skid-mounted systems. Leading models, such as the STLB-20 to STLB-100 series, provide a full-cycle automated workflow—from feeding and enrichment to discharge and self-cleaning.

2.Application Gold Ore Processing Equipment

• Continuous Placer Gold Mining: Ideal for 24/7 non-stop gold extraction in high-throughput alluvial deposits and paleochannels, significantly boosting operational efficiency.

• Hard Rock Gold Pre-concentration: Serves as the core gravity separation unit in grinding circuits, enabling an integrated "Crush–Grind–Auto-Discharge" workflow with minimal manual oversight.

• Tailings Resource Recovery: Provides automated scavenging of historic tailings to recover micro-fine gold (grades 0.1–0.5 g/t), aligning with "Zero-Waste Mine" initiatives.

• Overseas Small-Scale Projects: Reduces reliance on skilled labor in regions with high labor costs or technical limitations (e.g., Africa, Southeast Asia), enhancing project economics.

• Mobile Processing Platforms: Can be integrated into trailers or containers to form an automated "Crushing–Grinding–Centrifugal Separation" skid-mounted system for rapid deployment and site relocation.

3.Working Principle Gold Ore Processing Equipment

• Slurry Feeding: Slurry with a concentration of 30–50% is pumped into the bottom of the high-speed rotating conical rotor.

• Centrifugal Enrichment: The rotor generates 200–600G of centrifugal force; high-density gold particles are flung toward and captured within the inner wall grooves, while light gangue is discharged via the overflow.

• Auto-Discharge Trigger: The PLC system automatically initiates the discharge sequence based on a preset timer (1–4 hours) or accumulated throughput.

• High-Pressure Backwashing: Solenoid valves open, and high-pressure water (0.1–0.2 MPa) jets from the rotor center, flushing the enriched concentrate into a collection tank.

• Closed-Loop Operation: Upon completion of discharge, the system resets automatically without stopping, immediately entering the next enrichment cycle for continuous operation.

• Remote Monitoring: Select models feature wireless communication modules, allowing real-time tracking of status, discharge frequency, and power consumption via mobile or PC.

4.Advantages Gold Ore Processing Equipment

• Fully Automated Operation: Eliminates manual downtime for discharge, increasing equipment utilization by over 30% with "one-button" start/stop.

• Superior Recovery Rate: Achieves 97%–99% recovery for fine gold (0.004–0.074mm), outperforming traditional semi-auto units (90–95%).

• 24/7 Continuous Capability: Supports non-stop operation, increasing daily throughput by 40–60% and significantly lowering unit processing costs.

• Reduced Human Error/Loss: The closed discharge system prevents concentrate spills or contamination during manual handling, ensuring stable recovery.

• Low Maintenance Intensity: Extended service life for key components (8,000+ hours) reduces the frequency of maintenance-related downtime.

• Smart Control Integration: Supports remote monitoring, self-diagnostics, and cloud data uploads, fitting the requirements of Smart Mines.

• Rapid ROI: Using the STLB-60 (10–15 t/h capacity) as an example, annual gold recovery of 2–4 kg typically results in a payback period of <10 months.
