Continuous
barge unloading
B

elgian-based Vigan Engineering
designs and manufactures port
equipment for dry bulk handling
and is widely recognized throughout the world as an expert in pneumatic bulk handling technology.
With their numerous advantages compared to grabs or other mechanical devices,
pneumatic barge unloaders have a wellestablished reputation among large-size
agribulk businesses all around the world.
Continuous barge pneumatic unloaders
have particularly proven their suitability for
discharging products such as all types of
cereals and oilseeds, raw materials for animal
feeding, as well as many other free-flowing
products like fertilizers, soda ash, aluminium
oxide (alumina) or emerging new commodities such as wood pellets.

Provimi Dresses in Green
In May 2013, Vigan installed a pneumatic
barge unloader at Provimi (part of the Cargill
Group) in Kaiseraugst, Switzerland. The
machine was painted in green to blend in
with the forest landscape, and the unloader
was mounted on a floating bridge to avoid
damaging the environment.
With an unloading capacity of 300 t/h
(metric tonnes per hour), the pneumatic
unloader is equipped with a four-stage turbo
blower directly driven by a main electrical
motor of 250 kW and controlled by frequency inverter (this speed variator enables
a flexible unloading capacity from 150 t/h to
300 t/h and optimizes power consumption
at all times).
The machine’s central tower includes
a high-pressure jet-pulse type filter (filtering area of 112m2) on a slewing pedestal
mounted on the stationary gantry.
The 15 metre long rotating boom is
completely hot-dip galvanized, with a lighting
36 | September - october 2013

system and floodlight for the illumination of
the barge hold. The vertical and horizontal
telescopic pipes are controlled by remote
control boxes (push button and radio types)
and Vigan provided a special cutting nozzle,
enabling the suction of less free-flowing
material such as soybean meal.

Efficiency: fast and perfect hold
cleaning
When unloading barges and other vessels, speed is a major challenge. It’s also
crucial for hold cleaning. Mechanical grabs,
for instance, offer a high unloading rate at the
beginning of operations.
However, the final cleaning of the hold
at the end of the process requires considerable attention from the crane operator and
the auxiliary workforce in the barge hold, in
order to co-ordinate tasks to achieve maximum efficiency.
With mechanical grabs, the remaining
layers of product in the bottom and along
the barge hold borders need to be gathered around the target area. This is usually
quite time-consuming (a real nightmare
for the manager in charge of productivity
targets) and also rather dangerous for the
workers.
On the other hand, pneumatic unloaders
behave like vacuum cleaners, efficiently sucking the product particles down to the hold
bottom. Thanks to the telescopic characteristics of the pipes and the rotating capability
of the boom supporting the conveying line,
the suction nozzle is also able to reach the
hidden corners of the hold.
Most recent attempts with other
mechanical continuous unloading systems
have failed, or have performed poorly when
attempting to provide an efficient final cleaning of the barge hold.
A single worker can manage the whole
barge unloading process, including when

behaving as the driver of the auxiliary
‘skid steer’ equipment and for final brushing of the products around the suction
nozzle.
For barges, it is quite common to achieve
an average efficiency rate of up to 80
percent with a Vigan pneumatic unloader
in comparison to only 60–65 percent with
conventional grabs.

Environmentally friendly
In terms of environmental friendliness,
the Provimi unloader’s green paint is just
the beginning. The machinery room is
noise-insulated with a turbo blower group
and high-performance silencers. Negative
pressure is maintained around the suction
nozzle, whose filtering system ensures
less than 10 µg of dust escapes per cubic
metre.
The lack of a grab crane means that the
boom can move at relatively slow speeds,
reducing any disturbance to nearby wild
animals. Finally, the use of pneumatic equipment eliminates the risk of spillage from
potential contaminants like nitrates.

Low power consumption
Most recent technological developments
such as the installation of frequency inverters, direct drive of the turbo blowers, optimized design of the suction nozzle, and the
general philosophy of pneumatic conveying
systems enable low power consumption.
For barge unloading, power consumption is
around 0.6–0.7 kWh/t.

Advantages of barge unloaders
Efficient barge unloading is indeed a challenge, but it is a must in most modern industries. Further to these advantages, pneumatic
continuous unloaders allow easy, low-cost
maintenance and have an almost nonexistent
accident risk.

  • 3. PORTS Continuous barge unloading B elgian-based Vigan Engineering designs and manufactures port equipment for dry bulk handling and is widely recognized throughout the world as an expert in pneumatic bulk handling technology. With their numerous advantages compared to grabs or other mechanical devices, pneumatic barge unloaders have a wellestablished reputation among large-size agribulk businesses all around the world. Continuous barge pneumatic unloaders have particularly proven their suitability for discharging products such as all types of cereals and oilseeds, raw materials for animal feeding, as well as many other free-flowing products like fertilizers, soda ash, aluminium oxide (alumina) or emerging new commodities such as wood pellets. Provimi Dresses in Green In May 2013, Vigan installed a pneumatic barge unloader at Provimi (part of the Cargill Group) in Kaiseraugst, Switzerland. The machine was painted in green to blend in with the forest landscape, and the unloader was mounted on a floating bridge to avoid damaging the environment. With an unloading capacity of 300 t/h (metric tonnes per hour), the pneumatic unloader is equipped with a four-stage turbo blower directly driven by a main electrical motor of 250 kW and controlled by frequency inverter (this speed variator enables a flexible unloading capacity from 150 t/h to 300 t/h and optimizes power consumption at all times). The machine’s central tower includes a high-pressure jet-pulse type filter (filtering area of 112m2) on a slewing pedestal mounted on the stationary gantry. The 15 metre long rotating boom is completely hot-dip galvanized, with a lighting 36 | September - october 2013 system and floodlight for the illumination of the barge hold. The vertical and horizontal telescopic pipes are controlled by remote control boxes (push button and radio types) and Vigan provided a special cutting nozzle, enabling the suction of less free-flowing material such as soybean meal. Efficiency: fast and perfect hold cleaning When unloading barges and other vessels, speed is a major challenge. It’s also crucial for hold cleaning. Mechanical grabs, for instance, offer a high unloading rate at the beginning of operations. However, the final cleaning of the hold at the end of the process requires considerable attention from the crane operator and the auxiliary workforce in the barge hold, in order to co-ordinate tasks to achieve maximum efficiency. With mechanical grabs, the remaining layers of product in the bottom and along the barge hold borders need to be gathered around the target area. This is usually quite time-consuming (a real nightmare for the manager in charge of productivity targets) and also rather dangerous for the workers. On the other hand, pneumatic unloaders behave like vacuum cleaners, efficiently sucking the product particles down to the hold bottom. Thanks to the telescopic characteristics of the pipes and the rotating capability of the boom supporting the conveying line, the suction nozzle is also able to reach the hidden corners of the hold. Most recent attempts with other mechanical continuous unloading systems have failed, or have performed poorly when attempting to provide an efficient final cleaning of the barge hold. A single worker can manage the whole barge unloading process, including when behaving as the driver of the auxiliary ‘skid steer’ equipment and for final brushing of the products around the suction nozzle. For barges, it is quite common to achieve an average efficiency rate of up to 80 percent with a Vigan pneumatic unloader in comparison to only 60–65 percent with conventional grabs. Environmentally friendly In terms of environmental friendliness, the Provimi unloader’s green paint is just the beginning. The machinery room is noise-insulated with a turbo blower group and high-performance silencers. Negative pressure is maintained around the suction nozzle, whose filtering system ensures less than 10 µg of dust escapes per cubic metre. The lack of a grab crane means that the boom can move at relatively slow speeds, reducing any disturbance to nearby wild animals. Finally, the use of pneumatic equipment eliminates the risk of spillage from potential contaminants like nitrates. Low power consumption Most recent technological developments such as the installation of frequency inverters, direct drive of the turbo blowers, optimized design of the suction nozzle, and the general philosophy of pneumatic conveying systems enable low power consumption. For barge unloading, power consumption is around 0.6–0.7 kWh/t. Advantages of barge unloaders Efficient barge unloading is indeed a challenge, but it is a must in most modern industries. Further to these advantages, pneumatic continuous unloaders allow easy, low-cost maintenance and have an almost nonexistent accident risk. &feed millinG technoloGy Grain
