What is a cable granulation system?

A cable granulation plant is a recycling facility designed for the mechanical processing of cable material. The goal is to separate the metallic components of the cable from the insulation and other materials and then separate them from one another.

Unlike manual wire stripping, a suitable system allows for the continuous processing of larger quantities of material.

Depending on the system configuration, typical input materials can include, for example, various types of copper and aluminum cables.

However, the types of cables that can actually be processed always depend on the specific machine and its technical specifications.

How does a cable granulation system work?

The exact operation varies depending on the manufacturer and system configuration. In general, however, cable processing can be broken down into several process steps.

1. Purpose of the cable material

At the start, the cable material is fed into the system. In larger systems, the material can be fed via a metering hopper, conveyor systems, or other upstream components.

It is important to ensure that the material feed is as controlled as possible so that the downstream machines can operate smoothly.

2. Pre-shredding

Depending on the size and nature of the feedstock, pre-shredding may be necessary before the actual granulation process.

Pre-shredders, for example, can be used for this purpose. They reduce larger pieces of cable to a size suitable for further processing.

Therefore, especially in larger recycling lines, shredders and granulators can be directly combined with one another.

3. Granulation

The actual grinding process then takes place in the granulator.

The cable material is further broken down and separated into smaller particles. This separates the metal and insulation material from each other to the extent that mechanical separation is subsequently possible.

The quality of this process step has a significant impact on the subsequent separation.

4. Separation of Materials

After crushing, the material consists of different fractions. These must then be separated from one another.

Depending on the specific cable granulation system, various separation methods and components can be used for this purpose.

The goal is to produce material fractions that are as clean as possible, which can then be further processed or introduced into the recycling cycle.

What components make up a cable granulation system?

Not every cable granulation system is designed the same way. Depending on the desired throughput, input material, and processing objective, different components can be combined.

These may include, among other things:

When selecting a system, therefore, one should not focus solely on the individual machine. What matters most is how all the components work together.

What role does a pre-shredder play?

A pre-shredder can play an important role, especially when dealing with larger or difficult-to-process feedstock.

It reduces the cable material even before granulation. As a result, the material reaches the next processing step in a more suitable size.

Whether a pre-shredder is needed depends, among other things, on the type of cable material, the planned system capacity, and the existing machine configuration.

For smaller cables or those that have already been prepared accordingly, however, the process may be structured differently.

Cable granulation plant or cable stripping machine?

A cable granulation system isn't necessarily the right solution for every business. Another option for cable processing is a cable stripping machine.

A cable stripping machine mechanically cuts through or removes the outer insulation so that the inner conductor can be exposed.

A cable granulation plant, on the other hand, takes a different approach: The cable is shredded, and the resulting material fractions are then separated.

Which technique is more appropriate depends, for example, on the following factors:

For facilities with different material flows, it may also be worthwhile to use different processes in parallel.

What should you look for when buying a cable granulation system?

Before making a purchase, you should define your company's requirements as precisely as possible.

The type of cable material available and the quantities to be processed on a regular basis are particularly important in this context.

Additional selection criteria include:

A system with high theoretical capacity is not automatically the most cost-effective solution. The machine, material flow, and desired result must be well-matched.

A new, used, or refurbished cable granulation system?

In addition to new machines, used and refurbished cable granulation systems are also an option for recycling companies.

Used machinery can be particularly appealing if a suitable system configuration is available. However, the purchase price alone should not be the deciding factor.

When purchasing used recycling machinery, factors such as its technical condition, wear parts, existing components, and suitability for the intended application should be evaluated.

A professionally overhauled system can also be an attractive alternative to purchasing a new one.

Cable granulation systems as part of a complete recycling line

Depending on the amount of material and the desired level of automation, a cable granulation system can be connected to other machines.

For example, this can result in a process chain consisting of material feeding, a pre-shredder, conveyor systems, a granulator, and separation.

The advantage of a coordinated recycling line is that the individual processing steps can be tailored to work in tandem. This makes planning the entire material flow increasingly important, especially at higher throughput rates.

Conclusion: The right cable granulation system depends on the material

A cable granulation plant enables the mechanical processing of scrap cable and the separation of its constituent materials.

The typical process ranges from feeding the material through possible pre-shredding and granulation to separation. However, the specific design of the plant depends on the type of cable material, the required throughput, and the desired processing result.

That is why it is important not to focus solely on individual performance specifications when making a selection. The key is to choose a machine configuration that matches the actual material flow of the recycling operation.

Shredder or granulator? Which recycling machine is the right one?

Shredding, processing, and recovering valuable materials: Both shredders and granulators play important roles in modern recycling processes. However, the machines serve different functions.

The technology required depends primarily on the feedstock, the desired particle size, and the subsequent processing steps. In larger recycling plants, shredders and granulators are even combined.

But what are the differences, and which recycling machine is best suited for which application?

Are you looking for a shredder, granulator, or other recycling machine? Discover the new, used, and refurbished recycling machines currently available at Diebels.

What does a shredder do?

The primary purpose of a shredder is to mechanically break down larger materials and prepare them for further processing.

Depending on their design and capacity, shredders can process a variety of materials. In the metal and recyclables industries, for example, they are used to reduce larger or bulky material fractions to a more manageable size.

This can be particularly useful if the feedstock is still too large or too uneven for the subsequent recycling process.

What is the function of a granulator?

A granulator is used when finer grinding of the material is required.

A typical application is cable recycling. Cables are shredded so that the various components can then be separated from one another.

The goal, therefore, is not simply to reduce the size of the material. Rather, granulation creates the conditions necessary for the subsequent processing and separation of the recyclable materials it contains.

Shredders and Granulators: What's the Difference?

The main difference lies in the respective processing step.

A shredder is often used for coarse shredding or pre-shredding. A granulator then further processes the material to produce a finer texture.

In simple terms, the process can be described as follows:

Feedstock → Pre-shredding → Pelletizing → Separation → Recycled Materials

Which of these processing steps are actually required depends on the specific material.

When is a pre-shredder a good idea?

Not all feedstock can be fed directly into a granulator. For larger or irregularly shaped materials, a pre-shredder can therefore be used before the actual granulation process.

Pre-shredding can help create a controlled flow of material for the downstream machines.

Especially with higher throughput rates, the interaction between the pre-shredder, conveyor system, and granulator can play an important role.

The individual components must be coordinated with one another in terms of their performance.

Example: Cable Recycling

Professional cable recycling may involve several processing steps.

Depending on the type of cable and the system design, the process might look something like this:

  1. Cable materials are collected and pre-sorted.
  2. Larger pieces of material are pre-shredded as needed.
  3. A granulator further shreds the cables.
  4. The resulting mixture of materials is separated.
  5. Metal and other components are recovered as separate fractions.

The appropriate machine configuration depends, among other things, on the type of cable and the volume of production.

What role does material throughput play?

When deciding between different recycling machines, it is important to consider more than just the material.

Equally important is the volume to be processed within a given time period.

A small recycling facility that handles manageable amounts of material requires a different machine configuration than a company that processes large quantities every day.

Important factors include, among others:

It is only through the interplay of these factors that the actual machine requirements are determined.

A single machine or a complete recycling line?

It is not always necessary to purchase a complete recycling facility right away.

If suitable equipment is already in place, an additional machine can effectively complement an existing process. For example, a pre-shredder can be installed upstream of an existing pelletizing line.

When setting up a new recycling line, however, care should be taken to ensure that the individual machines are compatible with one another.

For example, a high-performance granulator is of little use if the upstream equipment cannot supply enough material.

Used Shredders and Granulators as an Alternative

Used or refurbished recycling machines may also be worth considering when expanding an existing facility.

The advantage is that proven machine technology can continue to be used, and the investment—depending on the machine and its condition—may be lower than that for a comparable new machine.

Before making a purchase, however, you should carefully review the technical specifications and condition of the item.

These include, for example:

Above all, it is essential to verify whether the machine is compatible with the intended material and the existing plant equipment.

Which recycling machine is the right one?

There is no one-size-fits-all answer.

Those who primarily need coarse pre-shredding should consider different machines than a company that wants to finely process material for subsequent separation.

In many recycling processes, therefore, the choice is not necessarily between a shredder and a granulator. Instead, both machines can perform different tasks within the same processing line.

It is crucial to consider the entire material flow.

Conclusion: Choose a recycling machine based on the process

Shredders and granulators perform different functions in recycling. While shredders are often used for coarser shredding, granulators handle the finer processing of the material.

The technique required depends on the starting material, throughput, and desired result.

Companies should therefore not only compare individual machines, but also analyze the entire recycling process. This makes it possible to put together a solution in which the various components work together in a technically sound manner.
