<p>Apparatus for use in producing pellets comprises a pelletizer comprising an annular chamber 29 partially defined by a pellet plate 25 against which spring loaded knives are urged. Pellets produced by moving the knives relative to the plate to repeatedly cut plastics extruded through apertures in the plate 25 are carried by a water stream out of the chamber. This stream enters the chamber via an inlet 40 and performs one cycle round the chamber before exiting the chamber with the pellets via exit 2 which is in the same plane as inlet 40. With this arrangement the axial extent of the pelletizer is reduced and the relatively short travel of the pellets promotes effeciency.</p> |
