Granulation of powder and diamond before cold pressing is an addtional production step that is usually only done when needed. However, there are a lot of advantages making pre-granulation reasonable:

  • higher mould life (if diamond and powder are granulated together as in Dr. Fritsch equipment)
  • better powder and diamond distribution
  • better flowability
  • lower dust exposure
  • better cold pressing properties
  • the possibility of using a volumetric coldpress (here granulation is mandatory)
  • for segments with set diamonds granulation of the powder is obligatory
