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 bars, 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. 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
