Blue Devil GF4000 industrial scrap shredders for ferrous and non-ferrous metals

The Blue Devil GF4000 twin-shaft industrial ferrous shredders are the best-selling model in the medium-light scrap recycling market. They make it possible to optimise the shredding of bulky scrap by increasing the density and largely satisfying the production requirements of steel mills and foundries. The cutting shafts are equipped with 4 planetary gearboxes (2 per shaft) and 4 hydraulic motors (2 per shaft), and can be powered by an industrial diesel or electric motor. The shafts create a powerful cutting action that creates less noise, less dust and greater cutting efficiency than all other rotary shears on the market.
