<p>An apparatus and process for the production of agglomerated pellets from a polytetrafluoroethylene (PTFE) resin powder. Such agglomerated pellets are commonly used in moulding apparatus. The pellets of this invention exhibit better and more consistent flowability and higher, more consistent bulk density than those made by previously known apparatus and methods. The apparatus includes a tilted, heated polygonal tube (12) provided at its discharge end with an apertured plate (50) with centrally disposed circular opening (52).</p> |
