Don’t you have any following problems with recycled material?
  • Recycled material crushed by a crusher isn’t uniformed so it is hard to use them in real production.
  • Using recycled material containing powder/dust, appearance defects such as white spots can happen.
  • Considering the quality of the products, we give up recycling expensive material.
  • It takes time to measure the material because the size of recycled material isn’t even.
Harmo's Gran cutter can help you to solve
these problems.

What is important to improve recycling rate is “Gran Cutter” not “Crusher”.
