AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.
