PVC Pellet Extruders

Description

The Theysohn twin-screw extruder XTS 122 is mainly used for pellet production. The XTS 122 extruder is a flexible high-performance extruder that achieves the highest melt quality through the proven processing units in 28D, 32D or 36D.

The wide range of different dosing units, which are also available in gravimetric versions, allows flexible feeding of several different products. The pellet extrusion line is completed with the Theysohn GKX pelletising head and matching downstream equipment.

Features

  • Parallel extruders with screw diameters from 88 - 136 mm
  • Conical extruders with screw diameters from 50 - 80 mm
  • Process lengths from 24 - 36D
  • Wear-protected screws and barrels in T5000 and T8000 (tungsten carbide)
  • Completely chrome-plated screws for soft PVC processing
  • Gravimetric dosing system
  • Control of the GKX pelletising head and downstream via the flexible TEC-5s extruder controller

Application

  • Hard and soft PVC
  • High-filled PVC
  • WPC (PVC, PE, PP)

GKX Pelletising Head

Description

The GKX pelletising head from Theysohn has been designed for pelletising rigid and flexible PVC as well as for highly filled PVC formulations. A process-optimised feed piece to the pelletising head reduces the dwell time of the material in the flow channel. The pelletising head housing can be easily and quickly separated from the extruder via quick-release fasteners and reassembled. The knives of the pelletising head can be adjusted to the die plate via a threaded spindle.

This enables readjustment during operation. The tested AIR-Through System prevents the pellets from sticking and adhering in the pelletising head housing and ensures optimum discharge. The GKX pelletising head is integrated into the TEC 5s extruder control system and can thus be controlled from the extruder.

Features

  • Special pelletising head feeder to shorten the dwell time of the material in the GKX
  • 1, 2, or 4 dies
  • Central cutting head
  • Chrome-plated version possible
  • Adjustable knives
  • Dies available in different steel qualities
  • Speed controlled cutting drive
  • 2 inspection glasses
  • Electrics integrated in the extruder control cabinet
  • Mobile pelletising head housing for quick cleaning

Application

  • For pelletising rigid and flexible PVC
  • For pelletising highly filled PVC formulations
  • For pelletising WPC

Downstream for Pellet Extrusion

Description

The pellets cut by the GKX pelletising head in the hot cut-off process are blown into a cyclone by means of a conveyor fan via an approx. 10 m long conveyor line. From there it falls via a switch into the cooling channel.

A BigBag filling station forms the end of the pelletising system. The lines between the GKX and the conveying fan and downstream cyclone can be flexibly designed.

Features

  • Space-saving installation variants
  • Single or double BigBag station
  • Up to 1800kg/h (depending on material and size of granulate)

Application

  • Pelletising rigid and flexible PVC
  • For pelletising highly filled PVC formulations
  • For pelletising WPC
