JKL MLPH Horizontal Pressurized In-Line Sampler

The JKL MLPH is an automatic in-line sampler engineered for the extraction of representative sample increments from horizontal pressurized pipelines conveying abrasive mineral slurries. Its heavy-duty mechanical design and controlled actuation system enable full cross-sectional interception of the slurry stream, ensuring technically valid sampling for process control and metallurgical accounting applications.

Operating Principle

The unit incorporates a horizontally traversing linear cutter that passes completely across the internal pipe diameter at a constant and controlled velocity. During each sampling cycle:

1. The cutter traverses the entire slurry stream cross-section.
2. A continuous increment proportional to the instantaneous flow rate is collected.
3. The increment is discharged into a secondary sampling line or collection hopper.

Primary Applications

• Final concentrate pressurized pipelines
• Flotation feed
• Cyclone feed circuits
• Tailings discharge lines
• Grinding and classification circuits

Particularly recommended for high-solids-content slurries exhibiting severe abrasive characteristics.

Key Technical Features

• Flanged horizontal in-line configuration for direct pipeline installation
• Cutter fabricated from reinforced structural steel
• Internal liners in wear-resistant materials (optional: polyurethane, ceramic liners, or hardened alloy steel)
• Pneumatic or electric actuator system with programmable control
• Industrial-grade pressure seals for continuous pressurized operation
• Adjustable cutter velocity according to pipe diameter and slurry flow rate
• Integrated drainage and flushing system
• Designed for PLC and SCADA system integration

Technical Advantages

• High sampling accuracy and repeatability
• Minimizes Fundamental Sampling Error (FSE)
• Reduces bias caused by particle settling and velocity gradients
• Specifically engineered for severe mining operating environments
• Low maintenance due to replaceable wear components

Benefits for Metallurgical Accounting

The JKL MLPH contributes to:

• Improved reliability of metallurgical mass balances
• Reduction of commercial discrepancies in concentrate shipments
• Enhanced real-time operational control
• Compliance with international sampling standards (aligned with ISO 13909 principles and recognized slurry sampling best practices)

Available Configurations

• Nominal diameters customized to client pipeline specifications
• Medium- and high-pressure versions
• Optional secondary sample collection system
• Carbon steel or stainless steel construction
• Fully enclosed versions for corrosive environments

Technical Conclusion

The JKL MLPH Horizontal In-Line Pressure Sampler is a high-performance industrial solution for concentrator plants requiring automatic, representative sampling of abrasive mineral slurries under pressure. It combines mechanical robustness, statistically sound sampling principles, and operational reliability, making it suitable for critical control points in mineral processing plants where sampling integrity directly impacts metallurgical accounting and commercial reconciliation.
