Balling mills

PTV-Series – Balling of pre-shredded materials

Functionality of the PTV balling mill

Balling mill with special crushing method

The material is fed into the machine by a feeder chute or flat belt centered above the rotor. First, the larger material that does not fit through the preset gap between the hammer and anvil is broken up or crushed. The composite material is then separated by further impact and friction via the balling beam, and the product is discharged via an installed grate basket in the desired material size/ball size. If the desired size or disintegration is still not sufficient, this process is repeated from the beginning and the material is further disintegrated or dislocated. Subsequently, depending on the product, the light materials such as fluff or dusts, for example, are extracted or separated from each other by specific gravity using air separation tables. In this way, a very clean heavy fraction is obtained, which can then also be easily separated from aluminum and other products.

Product examples for the PTV balling mill:

  • Automotive Shredder Residues (ASR-Automobile Shredder Residues)
  • Cable Recycling
  • Non-ferrous mixed scrap processing
  • Electrical scrap (WEEE – Waste from Electrical and Electronic Equipment)
  • Various other products with a metal content that can be ballasted

Electronic Scrap (e-scrap), ASR, IBA and other products

Recovery of a clean metal fraction from all kind of products


The PTV can be used to process a wide variety of products and is particularly suitable for preparing the metals for subsequent further separation and processing. After the material has been shaped and balled by the PTV, the various products such as heavy metals, aluminum and other valuable products can be separated from residues such as rubber and plastic. In this way, pure products can be recovered and returned to the material cycle.

Refining of Non-Ferrous Metals

Preparation of non-ferrous metals for optimal separation


High value recyclable resources such as electronic waste (WEEE), automotive shredder residues (ASR) and electric cables are a significant source of secondary raw materials that can be returned to the circular economy. Our PTV crushing mill enables the liberation and shaping of copper and other heavy metals from compounds, hybrid material, copper cables, plastic insulation for further separation and direct commercialization with a copper smelter.
