Densifier 

Typical Applications: LDPE, HDPE, PP (BigBags, Carpets)  , PO-Mixed fraction, PVC, PA6 (Nylon), PET-fibers.

Example:

ldpe motley

Agrofilm-Flakes washed and dried
with centrifuge ca. 0.08 mt/m3

Densified Material ca. 0.45 mt/m3

Description of Operation                 movie Video shows Densifier in Operation

The densifier increases the "loose" weight of flakes of the above indicated materials to about 0.45 mt/m3,  thus increasing hte performance of the extruder. The material is also degassed and completely dried. The densifier  operates in "batches" and the processing chamber is loaded before and during the process.

The high-energy-blades shred the material and  press it under the rotor due to its design. The friction heats the material to the processing temperature. At this temperature the material becomes highly viscous. 

Subsequently cold water is injected into the process which causes the material to densify.  The whole process is automatic for the new models.
