INHOUSE Plastics Recycling

NOTHING TO WASTE

Don’t waste it: With our compact solution combining primary shredder and granulator, it has never been so easy to make plastic waste, defective products or off-cuts ready to re-enter the production cycle. Enjoy maximum productivity with our highly efficient, robust and low-maintenance components.

SHREDDER REQUIREMENTS

In this case shredding is considered a protective and efficiency-enhancing measure. During the process, high pressure is used to push the material – in the form of blocks or chunks – against the processing machine’s components. Shredding is necessary to safeguard the high-speed granulator, and the entire process, from downtime. Furthermore, foreign objects might enter the process, and in this way they are easily shredded and subsequently discharged.

Anforderung an den Shredder

Als Nachzerkleinerer oder auch Granulierer wird in der letzten Prozessstufe aufgrund des bereits „sauberen“ Materials, üblicherweise ein schnelllaufendes Rotor- Zerkleinerungssystem eingesetzt und zielt auf ein exaktes Endkorn von 15-30mm. Die schnelllaufende Komet Serie mit seinem Leistenmesser und dem stets exakten Schnitt ermöglicht höchsten Durchsatz bei höchster Verfügbarkeit, bis zu 24h am Tag.

Anforderung an den Shredder

Der Zerkleinerer muss dafür besonders robust und störstoffresistent ausgeführt sein, um die hohe Bandbreite an Inputmaterialien zu meistern. Das Ziel der Zerkleinerung ist eine wirtschaftliche Aufbereitung mit geringsten €/t-Kosten für den Betreiber mit einem stets konstanten Austrag von 50-100mm,  fix und fertig verwendbar zur Befeuerung im Zementofen Kalzinator oder als Wirbelschicht- Brennstoff. Der POLARIS als die Kompaktlösung erfüllt die Anforderungen am besten.

FEEDING

In this step, the material is fed into the machine via a conveyor belt. Materials can be supplied to the conveyor belt via a wheel loader or a forklift. To facilitate continuous feeding, our shredders permanently communicate with the conveyor belt and subsequent processes such as granulators or extruders. The metal detection system directly connected to the system control protects subsequent processes. This is necessary to guard the granulator, which is sensitive to foreign matter, and to prevent the high costs caused by downtime.

Shredding

In the second step, the visually inspected material is shredded. The robust Lindner shredder splits the material into the right output size for subsequent processes. To achieve the best possible throughput the shredder, conveyor and granulator continuously communicate and control the speed and the amount processed.

Granulation

The material coming from the foreign matter-resistant shredder is fed into the granulator and processed to the required particle form. Rotor speeds of 600 rpm are normal in this process. Due to the high speed, it is necessary for the material to be as perfectly prepared as possible to avoid the granulator malfunctioning.

GRANULATE COLLECTION

In this step, the material that has been processed by the granulator to a particle size of 8–10 mm is sucked into containers like big bags or directly transported for further processing.

PROCESSING WASTE FROM PLASTICS PRODUCTION

Shredding of plastics waste and rejects ensures efficient recycling

In-house recycling for efficient production processes – plastics and other production waste are important raw materials in the manufacturing of plastic products. Linder shredders were developed with precisely these requirements in mind. Thanks to an adjustable cutting gap and variable screens, you can customise the particle size to the needs of your subsequent processes.

Our primary shredders are resistant to foreign objects and are able to shred hard, rigid plastics to a particle size of <10 mm, as is necessary for recycling purposes. Since the material is often bulky and slightly contaminated, it is not possible to feed the material directly into the granulator. That’s were the primary shredder comes in, splitting the materials to protect the granulator or extruder and minimise the costs of downtime.
