Grab Pneumatic Ship Unloader

The grab pneumatic ship unloader is a high-efficiency bulk material handling system combining a mechanical grab (clamshell bucket) with a pneumatic conveying pipeline. The grab digs into the ship’s hold to collect coal, grain, cement, or other powdered/granular materials, then feeds them into a suction nozzle where powerful air flow transports the material through sealed pipes to shore storage. Typical capacities range from 300 t/h to 2,000 t/h, handling vessels up to 100,000 DWT. This unloader minimizes dust emission and product loss, making it ideal for environmentally sensitive ports.

[1] Bulk Cargo Terminals – Unloading coal, iron ore, and grain from large ocean-going vessels.

[2] Cement and Clinker Terminals – Dust-free transfer of powdery materials from ship holds to silos.

[3] Grain Import Ports – Gentle handling of soybeans, corn, and wheat with low breakage.

[4] Fertilizer and Chemical Ports – Pneumatic conveying prevents contamination and moisture. [5] Power Plant Coal Jetty – Supplying coal to conveyors with reduced dust and spillage.

[1] High Efficiency – Continuous grab feed + pneumatic transport achieves steady, high unloading rates.

[2] Low Dust Emission – Sealed pipeline system prevents dust pollution, meeting strict environmental regulations.

[3] Low Material Loss – Spillage and wind loss are minimized; clean operation.

[4] Gentle on Materials – Pneumatic suction reduces product degradation compared to mechanical impact.

[5] Compact Design – Small footprint on quayside compared to belt conveyor unloading systems.
