Product Specification

AI-driven automatic liquid level control system for flotation cells

1.Product Introduction Ore Beneficiation Equipment

The AI-Driven Automated Level Control System is the intelligent core of flotation cell management. By integrating high-precision sensors with AI algorithms, it enables real-time monitoring and dynamic regulation of pulp levels. The system architecture consists of a Perception Layer (ultrasonic/float level gauges), a Control Layer (PLC + AI Engine), and an Execution Layer (electric valves or VFD pumps). It provides millisecond-level response to fluctuations, ensuring a stable froth layer and significantly enhancing separation efficiency. Furthermore, it supports seamless integration with reagent dosing and froth imaging modules to establish a comprehensive, closed-loop intelligent control system.

2.Application Ore Beneficiation Equipment

• Large-Scale Polymetallic Concentrators: Stabilizing pulp levels during roughing and cleaning stages to maximize concentrate grade and recovery.

• High-Value Associated Mineral Recovery: Enhancing micro-fine mineral capture in Cu-Mo separation and gold tailings reprocessing through precision level management.

• Smart Retrofitting of Legacy Plants: Replacing manual weir adjustment with automated systems to transition from "experience-driven" to "data-driven" operations.

• Tailings & Environmental Management: Enabling interlocked level control in tailings pump pits and thickeners to mitigate spill risks and reduce water consumption.

• Laboratory & Pilot Platforms: Supporting collaborative level control experiments across multi-cell series to facilitate flotation kinetics research.

3.Working Principle Ore Beneficiation Equipment

• Perception Layer: Utilizing dual-redundant sensors (ultrasonic + float) to collect real-time pulp level data, combined with froth imaging analyzers to identify mineral enrichment status.

• Control Layer: The AI model fuses parameters such as slurry density and feed rate to dynamically optimize PID control strategies, providing advanced disturbance compensation and precise regulation through a combination of feedback and feed-forward loops.

• Execution Layer: Adjusts the opening degree of discharge valves or pump frequencies to regulate discharge flow, thereby stabilizing the froth layer thickness.

• HMI (Human-Machine Interface): The supervisory system provides visual displays of level curves, control commands, and alarm logs, supporting remote monitoring and automated alerts.

4.Advantages Ore Beneficiation Equipment

• High-Precision Control: Maintains level accuracy within ±2mm, a 70% improvement over manual adjustment.

• Rapid Response: System response time is <3 seconds, preventing efficiency drops caused by sudden surges or level fluctuations.

• Increased Recovery: Boosts concentrate recovery by 2%–7% while reducing tailings grade by 30%–50%.

• Energy & Resource Savings: Optimizes aeration and discharge flows to achieve 8%–12% energy savings.

• Stability & Reliability: Boasts a system availability rate of >99% and a fault prediction accuracy of >90%.

• Extensibility: Supports linkage with reagent dosing, density, and grade analysis systems to build a Digital Twin of the plant.

• Significant ROI: For a 1,000 t/d plant, the system can potentially increase annual concentrate production by 12,000 tons, leading to a rapid return on investment.
