    Mineral Intelligent Ore Sorting System

    The X ray sorting machine is a fully automatic equipment that utilizes machine vision, deep learning, automation control, mechatronics integration, high-performance computing, and big data technologies. It simulates human visual perception and brain function by different spectral imaging to distinguish the surface corrosion color, texture, fluorescence, energy spectrum, X-ray transmittance, and other features of the ore. It can rapidly and accurately perform qualitative and quantitative analysis of the ore and effectively select the desired ore.

    Application Range

    Non-ferrous metal ores:antimony, gold, copper, lead, zinc, tungsten, molybdenum, tin, nickel, vanadium, titanium, etc.

    Ferrous metal ores: wolfram, iron, manganese, chromium, etc.

    Precious metals: gold, silver, etc.

    Fluorescent ore: scheelite, fluorite, calcite, Malayite, Zircon, lepidolite, dolomite, stratocite, icelandite, opal, massive fluorite, diamond, etc.

    Working Principle

    The lump coal or ore block is uniformly spread through the feeding/belt device, and transferred by the conveyor belt to the position of the X-ray recognition system.

    The ore sorting machine utilizes XRT (X-ray transmission imaging) technology to automatically collect X-ray images of clean coal and gangue, or high/low grade mineral blocks and identify them.

    The ore sorting system integrates high-speed computing units and an array of high-pressure gas jet devices to automatically sort mineral blocks based on the image recognition results.


    Green Environmental Protection
    No water needed, no medium required, no coal slurry produced, no toxic and harmful substances used, and no toxic and harmful gases generated.
    High Sorting Accuracy
    With the help of high-precision detectors, multi-technology fusion, AI algorithms, and high-precision control systems, precise spraying can be achieved.
    Low Energy Consumption
    By adopting centroid air-blowing technology, the loss of high-pressure gas is greatly reduced.
    High Intelligence
    The system runs fully automatically, with remote data transmission and remote fault diagnosis, achieving unmanned operation.
