TDS is the latest generation of cost-effective X-ray sensor-based dry sorter. It has become a game-changer technology that is revolutionizing the mineral and coal processing industry. There have been over 100 installations within 3 years since product launch in 2015, and the TDS dry sorter has a wide range of applications from processing all types of coals to non-coal materials, from surface mines to underground mines, from fixed installations to mobile systems.

Working principle:

Feed materials, either ROM coal or ore particles, are fed onto a moving conveyor belt by the vibrating feeder. A dual X-ray source and a CCD camera (optional) mounted above the belt scan each particle on the belt. Software algorithms then identify the parties and calculate their trajectory off the belt, and a computer-controlled air jet separates target particles accordingly. All these actions happen within a very short period of time as the belt typically travels at 2.5 to 3 m/s. The computer-controlled solenoids on the air jet can open and close within milliseconds. A dust collector is equipped in the system to capture the fugitive dust generated during the separation process.

Key features:

  • A completely dry process

  • Wide feed size range (25 mm to 300 mm) & high unit capacity (up to 380 tph)

  • High efficiency, misplacement < 3%

  • Proprietary algorithms optimized with robust hardware

  • Smart control system & unattended operation

  • Remote control and trouble-shooting over the internet, self-diagnosis.

  • Radiation safety compliance

  • Low OPEX & low maintenance
