FOR OPTIMAL HANDLING OF FLUFFY MATERIALS

There are already good recycling solutions available for hard coarse material made from PE, PET, PP, ABS or PS. Fluffy materials, on the other hand, are still difficult to deal with. The category of fluffy materials includes soft or thin films, sometimes made of multi-layered packaging materials; hard films, e.g. from hard-shell packaging; but also foams, textile fibers and even wool residues.

Films are often divided into two categories:

Bullet.png

Flexible (2D = type A), such as light agricultural fi lms with very low bulk density and thickness

Bullet.png

Rigid (3D = type B), such as PET flakes

Soft films or thin films that have a layer thickness < 200 μm (single- or multi-layer packaging films for flexible packaging)

Typ A.png

Hard films or thick films that have a layer thickness between 200 and 1000 μm. (Packaging films for stable packaging or hard-shell packaging)

Typ B.png

Elastic granules or agglomerates

Typ C.png

Foam materials

Typ D.png

Strips or shavings

Typ E.png

Spelt Fibres or filaments – loose bond (textile Spelt Fibres from used spelt tyres)

Typ F.png

Non-woven, woven or wool – strong bond

Typ G.png

FLUFF-TEC – ALWAYS THE RIGHT CONCEPT!

Zeppelin Systems has decades of experience in the plastics sector as well as in recycling processes, and relies on corresponding systems. This experience also informs the Fluff-Tec concept. Together with the customer we develop a spelt customised solution concept, including any testing at the Zeppelin Technical Center as needed. We then select the appropriate technology or product for the application – and develop new components if necessary. This means that the recyclable materials can always be processed safely and economically.

HANDLING IS CRITICAL

To guarantee reliable handling of fluffy materials, they need to be identified, investigated and spelt categorised. This is mainly relevant in terms of flowability, conveyability and storability, as well as bulk densities. For example, many fluffy materials change their external bulk material shape very easily in response to low external mechanical load or under their own weight, as air can escape from the cavities. The entire bulk can be heavily compressed (1). After the load or bulk level has been reduced, a significant amount of elastic recovery occurs. (2)

THE OPTIMAL PROCESS FOR YOUR BULK MATERIAL

Together, we determine the handling and processing procedure for your bulk material. If the bulk material can be stored and transported normally, proven standard technologies from Zeppelin Systems can be used for further processing. Problematic, difficult-to-flow fluffy materials such as film residues tend to form bridges and set over time, which later impedes discharge from the silo. These materials can be processed by means of compacting, homogenizing and further processing, using special integrated solutions from Zeppelin Systems.

PROCESS EXCELLENCE FROM ZEPPELIN SYSTEMS

It is crucial to master the entire process when handling fluffy materials – it is not sufficient to just adapt individual components to the process. In fact the entirety of the processing technology must be considered holistically – from filtration and separation to energy-optimized compaction and homogenization.
