WRP-12i In Line Pelletizer


Jinhua Machinery’s water ring pelletizer connects directly to the end of the extruder, Jinhua Machinery Screen Changer or Melt Pump via a short coupled adapter allowing polymer to flow horizontally from the extruder to the in-line die plate.
The rheologically optimized design minimizes polymer inventory between the extruder and die plate and evenly distributes polymer flow to each die plate hole.

The result is a consistently uniform pellet.

Reclaim, masterbatch, and
compounders will benefit by improved pellet quality during both short and extended production runs.
The in-line design reduces inlet pressures which can allow for increased production rates. Polymer purges quickly through the in -line die plate for quick color changes, which maximize production time. The retractable cutter head allows quick access to change blades and remove die plates for cleaning or screw removal.

An open trough cooling system allows easy operator response to process changes.
A new cylindrical pellet dryer provides improved 360° access to dryer rotor for cleaning and pellet removal. Pellet flow through the dryer is streamlined to eliminate pellet stagnation and promote efficient pellet drying. An integral dryer blower exchanges dryer air 50 times per minute to provide improved pellet dryness.
