Eccentric Hot Face Pelletizer

Product Description

Eccentric hot face pelletizer belongs to: melt pelletizing (hot cut). It means melt coming from a die that is almost immediately cut into pellets that are conveyed and cooled by water spray.


The eccentric pelletizer is the optimum pelletizer for the production of temperature and shear-sensitive plastics. It is designed especially for the pelletizing of soft PVC, hard PVC, HFFR recipes or compounds for low, medium and high voltage cables based on elastomers.


The eccentric pelletizer is connected directly to the single shaft discharge screw. The screw builds up product pressure gently to achieve an even material flow through the die plate.


The die plate is fixed to the flange of the cylinder and can be removed quickly and easily for cleaning. It is heated by a die-cast ring heater. The distance between the shaft and the die plate can be changed to optimize the die flow.


The cylindrical product strands emerging from the die plate are cut into pellets by the rotating pelletizer knives. The pelletizer knives are mounted on a ergonomically designed knife rotor arranged eccentrically to the die plate which has a continuously adjustable speed. The design of the die plate, i.e. number, diameter and geometry of the die holes is adapted individually to the material properties and customer requirements. The pellet length can be influenced by variation of the knife blade speed. In some product applications a water mist is formed by spraying water into the pelletizer hood. This prevents the pellets from sticking after cutting.

Advantages

●  Improve the output efficiency of the module, effectively reduce the extrusion pressure, increase the extrusion output, and guarantee the extrusion quality.

●  The flow path between the extruder screw and the template is very simple and compact.

●  The cutter angle is easy to adjust, and the axial distance between the cutter and the template is easy to adjust.

●  Used in conjunction with a fluidized bed and other equipment.



Application

It is especially suitable for processing materials such as PVC, EVA, cross-linking materials that are very sensitive to temperature and flow path shape.
