When selecting a recycling machine, it is not only the material to be processed that plays a decisive role. Equally important is the question of how much material is to be processed per hour or per workday. A machine that is too small can quickly become a bottleneck, while an oversized system can result in unnecessarily high investment and operating costs.
For recycling companies, scrap dealers, and waste management companies, it is therefore important to realistically estimate the actual material throughput before purchasing a machine.
In simple terms, throughput describes the amount of material a recycling machine can process within a given period of time. However, it is not enough to focus solely on a theoretical performance value.
The actual performance achieved is influenced by, among other things:
Therefore, the key factor is always how the entire recycling plant works together.
Businesses that handle manageable quantities of material do not necessarily need a large recycling plant. More compact machines can be a cost-effective solution, especially for smaller or regularly recurring batches.
This applies, for example, to companies that wish to recycle cables, metals, or other recyclable materials from their own operations.
A properly sized machine can reduce investment costs while ensuring good capacity utilization.
As material volumes increase, the demands placed on recycling technology also change. In such cases, it is not enough for the actual shredding or processing machine to be sufficiently powerful.
Components such as:
must be coordinated with one another.
A high-performance main machine alone does not guarantee high overall throughput. If, for example, the material feed is too slow, the downstream equipment cannot fully utilize its potential capacity.
A metric ton of cable places different demands on a recycling machine than a metric ton of mixed metal scrap.
In cable recycling, for example, cable granulation systems, cable stripping machines, pre-shredders, and separation technology can be combined.
For processing scrap metal, other machines are suitable, including:
Therefore, the required throughput should always be considered in conjunction with the specific type of material.
In certain applications, a pre-shredder can be an important component of the recycling line. It prepares the input material for the subsequent processing steps and can ensure a more consistent material flow.
Especially in larger facilities, it is crucial that the individual machines are properly coordinated with one another in terms of their capacities.
This is how several individual machines are combined to form a functioning processing line.
Once the required throughput has been determined, the next question that often arises is: Does it have to be a new machine?
Not necessarily.
A suitable used recycling machine can be an attractive alternative, especially when the investment budget is limited. The key factors are its technical condition, performance, and suitability for the intended material stream.
New machines, on the other hand, offer advantages when a recycling solution needs to be tailored precisely to specific requirements or when an existing facility needs to be expanded for the long term.
The decision should therefore not be based solely on the purchase price.
When comparing different recycling machines, people often look first at the maximum throughput. However, other factors are also relevant to a facility’s cost-effectiveness.
These include, for example:
A machine with a high theoretical throughput is not automatically the most economical solution.
The company's future development should also be taken into account when purchasing machinery.
Anyone who is already operating at full capacity and expects material volumes to increase should check whether the planned recycling technology can be expanded in the future.
Modular plant designs can offer advantages in this regard. Depending on the system, additional machines or processing steps can be added later without having to replace the entire recycling line.
The ideal recycling machine is not necessarily the largest or most powerful one. What matters most is that the type of material, actual throughput, and operational processes are well-matched.
Before making an investment, companies should therefore carefully analyze which materials are processed, what quantities are generated on a regular basis, and what results they hope to achieve through processing.
Based on this, it is possible to select a recycling solution that is suitable for the operation from both a technical and economic standpoint.
