Online LIBS Elemental Analysis
The online LIBS elemental analyser, developed by our partner Nuctech, is based on laser-induced breakdown spectroscopy (LIBS) technology, is specifically designed for mine conveyor belts and metal separation scenarios,
enabling real-time online detection and analysis of ore and metal components. This device is directly integrated above the conveyor belt. It uses high-energy laser pulses to excite the plasma on the surface of ores and metals and combines AI algorithms to analyse spectral data. It can complete qualitative and quantitative analysis of over 50 elements such as Fe, Cu, Li, and Mg within 1 second, with detection accuracy reaching the ppm level and repeatability error less than 5%.
The system adopts a modular design and supports seamless integration with various central control management platforms. It can obtain ore and metal detection data once every second
and is compatible with high-speed conveyor belts (≤4m/s), providing a contactless and full process detection solution for the detection process.
Product Category: Rapid Analysis for QA/QC, Elemental Analyzer, Cement & non-metallic resources, Coal, Metal Ore Mining.
Application
- Real‑time quality analysis for conveyor‑belt ore/coal/cement grade monitoring
- Metal sorting and separation
- High‑speed production line elemental detection (≤4 m/s belt speed)
Features
- Fully automatic high throughput. It operates continuously for 24 hours, obtaining detection data once every second without any manual intervention.
