Container pelleting plant (1.5-2.0 t/h)
How a complete pelleting system fitted into a 40-foot container
The idea for this system arose from a clear practical requirement: a complete pelleting line should be able to be operated independently of buildings, infrastructure and fixed locations. Many operators wanted a solution that is mobile, can be put into operation quickly and works where the raw material is actually produced. A stationary large-scale plant would be oversized, cost-intensive or not eligible for approval for such applications.
This consideration gave rise to the concept of the mobile container pelleting plant, which enables an output of around 1.5 to 2 tons per hour. The entire process chain is integrated into a 40-foot HighCube container, including all machines, control technology and conveyor units.
Process chain in the container
The process begins with material intake, where the raw material is evenly dosed and fed into the processing system. A compact hammer mill performs the necessary size reduction to ensure that the material has a suitable particle size for pelletizing. The material is transported pneumatically into the pre-hopper via a closed conveyor section.
In the next step, the material is fed into the pellet press via a controlled dosing system. If necessary, additives can be mixed in to influence the mechanical properties or quality of the end product. The pellet press used is optimized for container operation, robust and powerful. An optional conditioner allows the moisture content to be adjusted manually before the material is pressed.
After the pressing process, the still-warm pellets are cooled in a counterflow cooler. This gives them a stable structure and a final temperature suitable for transportation and storage. Fines are then separated via a compact screening unit and automatically returned to the process.
The entire electrical and control technology is housed in a separate switch cabinet area, protected from dust and environmental influences. The system supports remote access, allowing diagnostics and settings to be made remotely.
Advantages of this system concept
The decisive advantage of this system is its mobility. As it is already fully pre-assembled and tested, commissioning on site is reduced to just a few connection points such as energy supply, raw material supply and pellet removal. This means that the system can be ready for operation in a very short time. It can be moved again or relocated to another site just as quickly.
Another advantage is the high level of service accessibility. All assemblies are easily accessible thanks to the side-opening container walls. Maintenance, inspections and repairs can be carried out efficiently without the need for major dismantling.
In addition, the construction costs of a stationary system are largely eliminated. No halls, foundations or complex infrastructure measures are required. The container design also facilitates financing and leasing, as the system is considered a movable asset and can be relocated or sold at any time.
Conclusion
The container pelleting system shows how a complete industrial process chain can be realized in a very small space without compromising on performance or product quality. It offers a flexible, compact and economical solution for operators who require mobile or location-independent pellet production. Thanks to its structure, ease of servicing and process reliability, it is suitable for both continuous operation and temporary use.
