This series of instruments employs Prompt Gamma Neutron Activation Analysis (PGNAA) technology to perform real-time, accurate analysis of key coal quality indicators, including ash content, moisture, total sulfur, calorific value, and ash composition.

On one hand, it enables real-time, precise monitoring of coal quality parameters at critical process points in coal preparation plants—such as raw coal, dense medium clean coal, total clean coal, and final product coal—providing essential data for intelligent optimization and control of coal washing processes. This maximizes clean coal recovery rates and ensures stable product coal quality.

On the other hand, it supports fully unmanned coal quality inspection for incoming coal at power plants, cement factories, and other end-user facilities, improving the accuracy of raw fuel data and enhancing overall plant intelligence. This contributes to realizing intelligent optimization and control throughout the entire coal preparation process.
