Manual picking has harsh conditions, high intensity, low accuracy, and safety risks. Intelligent dry separation completely replaces manual picking.

Wet washing consumes large amounts of water, causes coal slime and wastewater pollution, and performs poorly on water-sensitive coals. Intelligent dry separation uses no water or medium, eliminates slime disposal issues, and adapts to various coals.

Gangue pre-discharge at the pithead reduces ineffective transportation costs. Accurate removal of gangue and low-grade intercalations improves clean coal yield and quality.

Intelligent underground dry separation enables "sorting – gangue discharge – backfilling" closed loop: backfill gangue into goaf to unlock pressed resources, reduce transportation energy, suppress surface subsidence, and cut treatment costs.

Mobile dry separation system enables rapid relocation and flexible deployment for scattered coal sources and open-pit mining. It reduces raw coal transportation costs and avoids coal breakage and dust from long-distance transfer.

Intelligent dry separation enables gangue reutilization: extract high-value minerals (kaolin, pyrite), recover residual coal from historical gangue dumps to prevent spontaneous combustion, and transform solid waste into resources.
