Dear shankar,

The mechanical cement unloader, which you are referring to, is most likely a screw conveyor unloader.

Your question about the average discharge rate of the machine, which you use, let us believe that you have hoped for a higher through the ship unloading performance than you right now experiences.

Screw cement unloaders can reach very high free digging capacities, however, the clean-up properties are reducing the overall discharge rate significantly.

In addition, the clean-up starts already when there is still a considerable volume of cement in the hold to be unloaded.

The clean-up capabilities are the cause of the relatively low TTS performance.

Special clean-up devices are made for screw unloaders.

Pneumatic cement unloaders are a better choice for clean-up

That is the reason that a pneumatic vacuum cement unloader requires a unit with a lower free digging capacity for the same TTS capacity than a screw cement unloader.

It would be appreciated if you could share a logging of some ship unloadings in the form of unloaded tons as a function of the unloading time.

Have a nice day
