Screw Conveyor System

The screw conveyor system for self-discharging cement carriers uses screw conveyors to transport dry material to and from the holds. The installation of compressors and pressure tanks also enables pneumatic discharging. A screw conveyor system for a self-discharging cement carrier uses vertical and horizontal screw conveyors to load and unload cement. Material is loaded for transport pneumatically or mechanically. The horizontal screw conveyor, fitted with valves and drop-off pipes, distributes the dry material over the holds. Each hold of the ship is fitted with a sloped aeration bottom to collect material in the centre of the hold. The vertical screw conveyor moves dry material up to deck level, where it is transferred to a horizontal screw conveyor. The horizontal screw conveyor then feeds it to either the central hopper or the mechanical outloading boom for pneumatic or mechanical unloading, respectively. Key benefits Low energy consumption during mechanical unloading Non-pressurised material transfer on board Controllable discharge capacity
