Pre-shredder for the recovery of scrap metal

The pre-shredders RIPPER FRANK series are two-shafts shredders, with asynchronous reversible rotors, which are suitable to process light ferrous and non-ferrous material bales, as well as to pre-shred end-of-life vehicles (ELV), construction & demolition scrap, industrial scrap and electronic scrap.
The variable speed and torque rotors work in asynchronous way, reversing their direction when necessary, and interchanging their function according to programmable and customizable work cycles.

Installed before a shredding line with hammer mill/s, the Ripper Frank pre-shredder facilitates loading by producing a uniform and homogeneous feed, lowering wear and maintenance cost for the hammer mill, causing a consequential decrease in operating costs and increase in both total capacity and value.

  • Energy saving: lower energy consumption on the downstream shredding line with hammer mill, which implies a substantial operating cost reduction
  • Safer pre-shredding operations, with a lowered explosion and fire risks, together with a reduced noise emission
  • Substantial increase in hourly production of the hammer mill/s;
  • Lower wear for the mill components, reduced downtime for maintenance;
  • Increase of the crushing lines availability rate.
