Shredding metal

Metal shredding is a necessary step in the recycling process, regardless of whether your scrap metal comes from the metal-processing industry, automotive industry, electronics recycling or the waste industry.

Whatever your needs, we have the right shredding system for your recyclable metals.6

What types of metals can be shredded???
Sheet metal waste

Shear shredders are ideal for shredding sheet metal scrap as it is a material that cuts cleanly. Whether for reducing shipping costs or preparing material for remelt, UNTHA shredders are built specifically for your needs.


Metal shredding
Specific characteristics and challenges

Recycling steel doesn’t just save billions in environment- and climate-related costs: Replacing the primary material with scrap saves millions of tonnes of CO2 emissions. This is not reflected in the price yet, but in future, consumers and politicians should be given the clear message that scrap minimises the use of raw materials, reduces environment-related costs and thus actively contributes towards climate protection.

There is no general answer to this question, as not every metal is the same. The right shredder will therefore depend on the shape, hardness and ultimate purpose of the metal recycling process. From reducing the metal volume in order to facilitate further processing in the smelting works to improved separation of varying metals and composites, we will always analyse your requirements together with you and determine the right unit with regard to input material, throughput and desired size of the granulate. The question of whether a single-shaft or four-shaft shredder is the best choice for your material also needs to be addressed.


Metal shredding using the XR Shredder

Single-stage metal shredding

Either the stationary or the mobile XR shredder is well suited for shredding metal and scrap in a single-stage operation. The XR technology combines highly capable shredding with lowest operating costs, making the XR shredder a powerful partner for metal recycling. The ability to fully process metal in a single stage makes the XR especially efficient and economical to operate.

  • Increased bulk density reduces transportation costs.

  • Consistent, well defined fraction is ideally suited for additional processing

  • Excellent liberation enables easy and complete separation, resulting in a purer final fraction

  • Simple, straightforward operation

  • Easy cleaning for fast changeover to different materials

  • UNTHA Eco Power Drive reduces power consumption, noise, and dust generation


Metal shredding in a four-shaft shredder

four-shaft metal shredder is best when well defined and consistent granulate of less than 8" inches is needed.

Depending on the model chosen, the RS series of four-shaft shredders are used in the following applications:

  • Metal turning and chips

  • Shredding assemblies to liberate mixed materials

  • Shredding outdated and reject products to protect the integrity of your brand

  • Depackaging canned food products

Thanks to its compact design, UNTHA four-shaft shredders are easy to integrate into existing facilities.

Commercial & industrial waste

Commercial and industrial waste is collected separately according to the respective components before being processed and reintroduced into the raw material cycle (recycling), or recovered for thermal recycling or for energetic utilisation (substitute fuels).

C&I waste
Electronic waste (WEEE)

Electronic scrap comprises old electrical and electronic devices, as well as components of these which can no longer be used.

Electronic waste
Files & data

The reliable destruction of information set down on paper (files, documents etc.) ensures that your sensitive and confidential data cannot get into the hands of third parties.

Files & data
Hard drives

While there are many methods of destroying data, only a process that includes physical destruction of the storage media can provide maximum security.

Hard drives

The generated plastic waste can be recycled through shredding, washing and subsequent generation of granulate to produce a recyclable material (for the recovery of materials or energetic utilisation).
