On-line Conveyor XRF Analyzer

Real-Time Elemental Analysis. Directly on the Conveyor.

CON-X provides continuous, non-contact and non-nuclear elemental analysis of material moving on a conveyor belt, helping mining and mineral-processing operations monitor grade variation and make more informed blending, beneficiation, and process-control decisions.

Baltic Scientific Instruments Designed and manufactured by Baltic Scientific Instruments, Latvia. Distributed and supported through an international partner network.

Overview

Better Visibility Into Material Grade

Laboratory analysis remains important for calibration and verification, but sampling provides results for selected samples at specific points in time. Material composition can vary between samples. CON-X adds continuous on-belt measurement to give plant teams more frequent information about the material moving through their process.

Continuous On-Belt Measurement

Monitor elemental composition of material moving on the conveyor, rather than relying only on intermittent sample results.

More Timely Process Information

Use ongoing grade information to support blending, beneficiation, and operational decisions.

Designed for Plant Integration

Measurement data can be integrated with plant control and monitoring systems using supported interfaces, subject to project configuration.

Non-Nuclear

CON-X is a non-nuclear device, without the burden of nuclear licensing, safety and high costs.

CON-X complements laboratory analysis; it does not remove the need for appropriate calibration and verification.

How It Works

How CON-X Works

The CON-X on-line conveyor XRF analyzer measures characteristic X-ray fluorescence from material moving on a conveyor belt. The system processes the detected signals to provide elemental measurement results over a configured measurement period.

  1. Measure

    The analyzer head is installed above or across the conveyor to measure the moving material without direct contact.

  2. Analyze

    The detector measures characteristic X-ray fluorescence signals associated with elements in the material.

  3. Use the Results

    Elemental results and configured averages can support grade monitoring, process decisions, historical trending, and plant-system integration.
