Handling and Transporting Powder and Pelletized Carbon Black BULK-FLOW’s Solution

Carbon Black is a manufactured form of solid carbon, specifically engineered in powder or pelletized structure depending on its end usage. The annual production of Carbon Black exceeds 10 million metric tons; therefore, the handling, transport and storage of the Product is of great economic importance.

The applications are varied and diverse such as in the Coating Sector where Carbon Black Powder is key for deep black paints. In the Plastic Industry, Carbon Black Powder is added to Polyolefin and Polyethylene to absorb UV Light and convert it into heat. Carbon Black is also essential in anti-static treatments; therefore, it is necessary for power cable production. In the Paper Industry, Pelletized Carbon Black is used for photo-protective products. Carbon Black also protects metal structures against oxidation. Rubber Carbon Black in its pelletized structure is very important in the industrial production of rubber components for different applications, particularly for the Tire Industry where it is used as a filler and reinforcing agent for rubber compounds.

Carbon Black is divided by its structure in Powder and Pelletized, with the latter in many subdivisions due to particle size and resistance. Each type has different handling protocols.
Carbon Black Powder is cohesive and difficult to unload, while Pelletized Carbon Black is free flowing but very sensitive as pellets should not be broken at loading and unloading.

Handling and transporting Powder and Pelletized Carbon Black

Powder Carbon Black can be loaded pneumatically as there is no danger of breaking the structure of the particle. The problem is due to the cohesive nature of the product; thus, it is very difficult to manipulate in ship holds or any other type of bulk transport.
Therefore, Carbon Black Powder is transported in 25 kg paper sacks or generally in big bags which means that the Powder must be transferred to a bulk silo at destination.

Pelletized Carbon Black flows freely but is fragile as the pellets should not be broken, therefore all kinds of internal transport, loading and unloading must be conducted with as little friction as possible.

Humidity: due to the high absorbency of Carbon Black moisture can alter the product and make it difficult to handle and useless for its main applications.

Titless Liner: Carbon Black trial at BULK-FLOW’s Technology Center

Bulk-Flow has conducted a Carbon Black Powder unloading trial for one of Europe’s most important Carbon Black logistic operators. The experiment was conducted on scale of 1:10 in Bulk-Flow’s Technology Center in Barcelona.

The experiment was a complete success, albeit the products cohesive nature, as residues were scarce and dust was not produced due to the sealed system. The unloading was complete without the influx of the force of gravity through tilting.

Bulk-Flow’s Tiltless Liner makes unloading protocols very standardized as merchandise is unloaded directly from the container into the importers silos or directly to their production line.
As no tilting is required to unload the bulk products, low-density products can be loaded in 40′ or 45′ containers without needing to contract special tilting truck at destination, which are expensive and not always available.

Bulk-Flow forwards the Tiltless Liner as an ideal solution for Carbon Black Powder and Carbon Black Pelletized in Deep Sea, Short-Sea Shipping and Intermodal Rail Transport.
