working principle:

When the screw unloader is working, the reclaimer is inserted into the tank at a suitable depth and the take-up device begins to rotate. On the one hand, the material is continuously supplied into the vertical screw conveyor, and on the other hand, the material entering the conveying pipe is prevented from being centrifugally pulled out in the circumferential direction. The material entering the vertical screw conveyor is transported upwards by means of a spiral blade that rotates at a high speed. According to different processes, the discharging system can be: screw conveyor, belt conveyor, chain conveyor, air conveying trough.

Basic parameters required for ship unloader selection:

1. Physical properties of loading and unloading materials (volume density, particle size, water content, honing performance, ignition point, etc.)

2. Ship type data of the maximum loading and unloading ship (captain, hatch size, depth, draught, etc.)

3. Hydrological water level data

4. Planned year-end turnover

5. Basic conditions of the terminal
