The Plast-Agglomerator is a compact, fully automatic, and a proven continuous system that converts thermoplastic waste into high quality, free flowing granules, which are later used as valuable raw material in further processes.

All thermoplastic materials such as PE, PP, PS, PA, PET, PVC, ABS, XPS, PLA and composite materials of any kind, in the form of bulky film, fiber, or foam waste, can be continuously recycled with the same system.

This PALLMANN Agglomeration process offers the unique advantage of material gentle agglomeration with minimum heat and minimum thermo-degradable damage; the material is heated up with friction heat only and is agglomerated, within a fraction of a second, right below the melting point. Furthermore, underwater cooling is not necessary.

 

The Feeding Hopper 

Precut material is conveyed into the feeding hopper by means of a pneumatic conveying system. In the hopper two stirrers keep the material moving, avoiding bridging and transporting it into a discharge screw. The speed of the discharge screw is frequency controlled, based on the load of the main drive motor of the Plast-Agglomerator. From the discharge screw the material is checked by a magnet for ferric metal, and then it is dropped into the feeding screw of the agglomerator.

The Plast-Agglomerator  

From a feed hopper, an auger feeds the material to the agglomerating chamber.  Through frictional only, the material is sintered or plasticized and pressed through the holes of a special die.  Agglomeration occurs in a fraction of a second, and right below the melting point of the material.  Material exiting the die is cut by rotating knives and then conveyed by air to a cyclone separator into the hot-melt granulator.

The Hot Melt Granulator 

The material from the agglomerator is sucked into the hot-melt granulator and is cut between stationary and rotating knives. The end product size of the agglomerates is determined by the size of the holes in the screen.

The intake section of the hot-melt granulator is double-walled and water-cooled. A magnet valve assures the water flow.

The agglomerated granules are collected in a material pick-up pan.

 

 

The Cascade Sifter

The cascade sifter is used to separate the dust particles. Air flows through the cascade sifter from the bottom to the top; the fine dust particles are carried upwards with the air and reach a cyclone via the sifting fan. The discharged fines are automatically returned into the agglomerating process.

The Granules Cooler 

The granules are pneumatically transported into a cooling tank where ambient air is blown producing a cooling effect. The granules cooler is only required for certain sensitive thermoplastic materials.
