AI Technical Summary
In existing coal gangue sorting devices, the single-stage sorting method results in low sorting accuracy, affects sorting efficiency, and makes it difficult to handle unstable raw coal conveying volume and uneven size.
A multi-stage sorting method is adopted, combining mechanical screening and intelligent identification technology. Two-stage sorting is carried out using a drum screen, an airflow separation box and an X-ray identification module. This includes drum screen screening of large-particle gangue, airflow separation of coal particles and gangue, X-ray identification of unseparated gangue, and removal of unseparated material by a robotic arm.
It significantly improves the accuracy and efficiency of coal gangue sorting, avoids blockage and environmental pollution, and ensures the stability and precision of the sorting process.
