Product Description



S120 series

The S120 series has been developed for particularly heavy industrial use. These two-shaft shredders are also known as rotary shears and are suitable in particular for shredding metals and tires. A four-shaft shredder is often used down-stream in a second shredding process to reduce granule size even further, and particularly high through-put rates can be achieved using this combination. Even with low speeds and very high torque the machines are capable of shredding heavy gauge metals. If you need to process very bulky or awkwardly shaped metal objects, a compression feeder will help to ensure the required through-put.



Some typical applications:

  •  Al-Mg feeders
  • AL-MG housings
  • Aluminium sections
  • Car tires
  • Electronic scrap
  • Metal drums
  • Paper egde strips
  • Paper sheets
  • Rolls of paper
  • Tractor tires
  • Truck tires


UNTHA S series machines are normally used for coarse shredding. However, depending on your specific requirements, they can also be fitted with perforated screens, sometimes called "perforated baskets", to achieve a reduction in granule size.



Changing the cutters is a simple task, as there is no need to dismantle the drive. This means that the down-times resulting from cutter changes are extremely short, even for these heavy machines.



Screening walls and special packing seals protect the bearings against penetration by dirt particles. The S series machines are also equipped with an automatic central lubrication system.


A range of different drive systems are available to meet your specific requirements.
