PGNAA Process Control
Real-time elemental analysis for on-line quality control in cement, coal, and mineral processing.
The Challenge
Real-Time Quality Control for Bulk Processing
Cement plants, coal processors, and mineral beneficiation operations depend on precise knowledge of raw material composition. Yet most rely on periodic laboratory sampling — collecting a grab sample every few hours and waiting for results. By the time the analysis returns, tonnes of off-spec material may have already entered the process.
Our Approach
Continuous Elemental Analysis on the Conveyor
ASPL Fusion deploys Prompt Gamma Neutron Activation Analysis (PGNAA) systems for on-line, real-time composition monitoring on moving conveyor belts. A neutron source irradiates the material, and characteristic prompt gamma rays reveal the elemental composition — continuously, without contact, and without stopping the belt.
Our NuKG knowledge graph has indexed 25 published PGNAA papers spanning cement, coal, and mineral processing applications.
Why It Matters
Key Benefits
Continuous Monitoring
Second-by-second composition data replaces hourly grab samples, enabling immediate process adjustments and eliminating off-spec production windows.
Non-Contact Analysis
The measurement is made through the conveyor belt without sampling, handling, or process interruption — suitable for abrasive, wet, or hazardous materials.
Proven Industrial Impact
PGNAA installations worldwide demonstrate 5-10% throughput improvements and measurable reductions in quality variability.
Who This Serves
Industries & Applications
- Cement plants controlling raw mix composition and reducing clinker variability
- Coal processing facilities monitoring ash, sulphur, and moisture content in real time
- Mining operations optimising ore grade measurement and mineral beneficiation recovery
- Bulk commodity handlers requiring continuous quality verification at loading terminals
