Environmentally Screw Ship Unloader / Vehicle mounted Screw Type Ship Unloader

Vehicle-mounted Screw Ship Unloader

Description

The following services are required from an unloading system:

low operating costs;

environmental compatibility in terms of dust and noise;

minimum weight and dimensions;

ease to operate and good mobility;

flexibility in the unloading of different types of materials;

compatibility in unloading from holds with different shapes and capacities;

high capacity of unloaded material;

reduced times for cleaning the unloading system between operations on different types of materials;

possibility of carrying out unloading operations even in bad weather (with the hold partially covered);

complete emptying of the hold with the minimum amount of human involvement inside the hold (for example, using front bulldozers in those areas where the unloading system is not able to reach).

The unloading of materials is transported in closed pipelines, with no dust pollution in the whole process, low noise and easy operation.

Compared with negative pressure ship unloaders and grab ship unloaders, it has obvious advantages of energy saving and environmental

protection. It is suitable for unloading of powder bulk materials such as cement, GGBS, fly ash, chemical fertilizer, grain, etc.
