Shredding and recycling of electronic boards are activities that Stokkermill has always taken into account in developing innovative technical solutions to overcome and solve some of the problems those make it difficult to extract metal materials from Copper-coated  fiberglass base. The abrasive capacity of the fiberglass makes the shredding of electronic boards quite problematic. The attempts made with the blade mills give uncertain results; after a few minutes the boards under the abrasive action of the glass contained in the fiber (fiberglass) will lose the sharpening making difficult if not impossible the operation. Simple blade mills for recycling have no use for recycling electronic boards. The impact mill is the only effective solution to obtain a quality granulation with controllable consumption of mechanical parts subject to friction. Once the right size of the output material has been obtained the separation systems made by Stokkermill will be able to carry out the separation of materials by dividing the inert part from the mix of metals and removing the ferrous component. The percentage of copper and other metals is not always constant but statistical studies carried out by Stokkermill and its user customers indicate a minimum value never less than 25% of metals. The recycling of PCB electronic boards allows the recycler to have control over the quality of its material and in particular the mix of metals that contain precious metal fractions.

Stokkermill has already built several plants in the way for recycling electronic boards and some of these are in the starting stage.

  • Shredding and recycling of motherboards
  • Shredding and recycling CPU cards
  • Shredding and recycling video cards
  • Shredding and recycling sound cards
  • Shredding and recycling memory cards
  • Shredding and recycling network card;
  • Shredding and recycling expansion card;
  • Shredding and recycling backplane;
  • Shredding and recycling riser card;
  • Shredding and recycling single-board computers.
