Air Pelletizer ELG, Water & Air Pelletizers EWA

The ECON air pelletizer was especially developed for processing wood and natural fiber compounds (such as WPC). Because water is used to cool and convey the pellets, processing wood-plastic compounds in an underwater pelletizing system requires a substantial amount of drying. Common drying methods are often unable to attain satisfactory levels of residual humidity.

The air pelletizer was designed to use air to cool and convey the pellets and thus eliminate any need to dry the pellets. At the same time, the system benefits from the thermal insulation, resulting in a uniform cut and easy conveying of the pellets from the "cool" cutting surface, without generating chains or agglomerates.

Among natural fiber compounds, the ECON air pelletizer is also well suited for processing PVC, which has a low inner specific heat, therefore requiring only minimal cooling.

The air pelletizer can also be combined with the ECON underwater pelletizing system, resulting in the water & air pelletizer EWA. Especially for laboratory applications this combination provides benefits in terms of flexibility and space requirements. With only a few modifications, one system can be used for both underwater and air pelletizing. Within just a few minutes the machine can be converted from air to underwater pelletizing and vice versa.

  • all advantages of the thermal insulation technology
  • highest flexibility
  • two different applications combined in one machine

The air pelletizing system consits of a pelletizing unit, a conveyor fan with noise reduction cover, piping and a cyclone and an electrical control system.

The melt is directed to the pelletizing head with the die plate installed, and the emerging melt strands are pelletized.. The pellets are moved by an air stream that is produced by the conveyor fan. By the air stream the pellets are dried and are discharged through the cyclone.

*The above-mentioned output ranges are reference values for standard pellets. Throughputs always depend on material properties and pellet size and therefore, they may deviate on an individual basis. Normally, for micro pellets the throughputs are lower.
