Vigan

Pneumatic Ship Unloaders

Most free flowing materials or slightly compacted & delicates cargoes

VIGAN pneumatic equipment are capable to handle a large variety of products with bulk densities usually between 0.5 and 1.5 . A most important aspect is the free flowing characteristics of the products such as for instance the cereals, the beans, the seeds and various products in powder with certain characteristics such as the particle size in order to allow an easy separation of the air and the product in the receiving hopper.

For products which are compacted during their sea transport such as soybean meal, VIGAN developed a specific device : Cutting nozzle. This is frequently used when unloading soy bean meal, a high protein by-product of crushing industries.

Many different models

In the tower type VIGAN unloaders, the boom that supports the suction pipes, the filter and the airlock are rotating on a slewing ring: the main engine room with the turbo blower(s) is stationary.

Once the unloading capacity in metric tons per hour is defined and also the size of the vessels to be unloaded, three most alternatives are feasible:

Stationary : it means that the vessel or the barge will have to move during the unloading so that suction nozzle will be able to browse the whole area of the hold(s)

Tractable : it means than by using an tractor for instance, the tower type equipment will be able to be displaced along the vessel or the barge.

Self-propelled : this alternative can be also feasible either on rubber wheels or on rails
