Handling

Significant advances have been made in the area of handling and shipping granulated and powdered goods in recent years. New air-tight sealing systems in particular for storage and transportation have greatly benefited the Carbon Black industry.

Rubber Blacks are usually marketed in the form of pelletized blacks, with selected types delivered in powder form.

Though pelletized or beaded Carbon Blacks have better flow and conveying characteristics – and are thus much easier to handle – than powdered versions, special precautions must be taken to prevent the pellets or beads from being crushed during transport. Otherwise, flow characteristics and onward handling may be significantly degraded, with downtime due to equipment failure often the consequence. For this reason, conveyor belts and bucket elevators are still commonly used for intra-plant Carbon Black forwarding.

For short distances, it is pellet hardness (wet-beaded Carbon Black is harder than dry- or oil-beaded Carbon Black) that determines whether screw conveyors, fluid channels or natural frequency conveyors are used.
