To discharge onto trucks and/or railway cars, it exists two main alternatives for the position of the machine(s):

Machines on ship deck


Discharge directly by blowing . It exists some risk of dust at the top of the discharge cyclone.

Discharge into a hopper. The suction may not be stopped between the trucks as the hopper is behaving as a buffer between them. It still exist some risk of dust at the top of the discharge cyclone.

Discharge into a hopper with its own self-cleaning filter: almost not dust and no spillage into the environment.

Discharge onto a small belt conveyor which will handle the products into the trucks: also minimum dust and spillage.

This alternative can be with a hopper on quay in order to avoid stopping the suction between the loading of the trucks

Machines on quay :


Delivery directly thanks to a discharge cyclone.
It exists some risk of dust at the top of the discharge cyclone.

In order to avoid stopping the machine between the trucks, the machine can blown the products into an hopper on the quay with delivery by gravity: same feasible alternative n° 2 or n° 3 as mentioned above when the machine is on ship deck.

Machine installed at the top of a hopper on the quay with delivery by gravity: almost not dust and no spillage into the environment. The hopper allows not stopping the suction between the trucks.

Machine with a small belt conveyor for direct loading of trucks for instance: minimum dust and spillage but the suction must be stopped between trucks.

To convey the products to the silos and/or a warehouse, a most convenient solution is the use of mobile belt conveyors : see drawing Delivery in warehouses and silos

Usually it is not convenient to blow the products on distance more than a 20 – 40 metres and at the end of the blowing line, the amount of dust blown out can be a major concern unless a dust separation system is installed : self cleaning filter.
