The environment is constantly changing and there is a need to become increasingly aware of the problems that surround it. This is why Bedeschi always pay attention to environmental issues, basing its projects on the stability and sustainability of the surroundings.
Nowadays there is often a need to transport raw materials and combustible solid material from one continent to another by sea. The ships that
do this are becoming bigger, so the modern port has to be equipped with all kinds of machines like shiploaders, ship-unloaders, cranes, conveyors, etc. to be able to complete the vessel’s loading/unloading process in the minimum time.
To guarantee efficiency in the ports it is necessary to optimize the position and the volume of the material that is stored and in transit, waiting to be shipped, to have adequate machinery to reduce the time of loading and unloading of the ships, and the delivery of the raw material. It is also necessary to organize the layout of the terminal in the most functional way and to reduce the number of operators needed through automation of the process, creating eco-friendly terminals by using dedusting equipment.
Thanks to its wide experience and knowledge in material handling, Bedeschi is successful in all of the above mentioned aspects. For example, when considering the bucket chain continuous ship unloader (CSU), all the solutions that Bedeschi proposes, and the executive design, are developed with the utmost care to dust control. The CSU will travel on rails and will be travelling and luffing boom type, it will be equipped with a bucketwheel elevator with continuous rotation for digging, with belt on the boom and central hopper to unload on a feeder that will load the pier conveyor.
When unloading, the material reclaimed by buckets will be luffed to the unload point, on the top of the elevator, and unloaded on a rotating plate which, independently from the rotation position of the elevator, will convey the flow on the boom belt. From the boom belt, through the central hopper, the material will be unloaded on the belt feeder under the hopper that will convey onto pier conveyor.
The proposed design with fixed foot will allows to extend the elevator enclosure, leaving the foot only on open air. While in operation, even at the real beginning of the unloading, the elevator foot is almost entirely inside the hold avoiding any possible dispersion. Once the material is inside the buckets, the entire stroke is protected.
Drive sprockets of the elevators will be equipped with a suitable device to avoid any possible egress of material inside the elevator enclosure.
CSUs are normally compared with a traditional grab type ship unloader. While the grab type ship unloader, even if equipped with ecological grabs, does not make it possible to completely eliminate dust dispersion during the transfer from the hold to the hopper — especially in windy conditions — with the CSU the route of the material is completely enclosed and the transfer points are equipped with dedusting systems.
This means that, once reclaimed by the buckets, the material can be fully enclosed without any possible dust dispersion.
Particular care will be taken to avoid any material accumulation inside the elevator in order to avoid any possible material falling during machine transfer operations. The unloading chute will be closed, with sealed inspection doors.
This is why the CSU ensures a homogenous material flow, with dust kept to an absolute minimum.
Going green and sustainable practice is now seen as an essential part of any business in the bulk industry.
Considering the fact that port’s infrastructures which consists of the land and space necessary for operations is expensive, Bedeschi is able to help the client by providing compact, functional, and eco-friendly machines that are able to adapt to a smaller space but are still able to offer the high volumes requested by the client.
