Tailor-styled recycling solutions for plastic waste – in this area HERBOLD
MECKESHEIM GmbH is an experienced full-line provider of recycling
technology: not only the full range of recycling technology from coarse
shredders via granulators to pulverisers, but also complete solutions for
the washing and separation of contaminated mixed plastic waste make up the
product range of the Meckesheim/Germany-based machine manufacturer.
As part of the vast product range HERBOLD MECKESHEIM will showcase the
following typical machine series:
• The Plastcompactor HV 50 for compacting films, fibres and foams: this
machine can transform flow-resistant materials into an agglomerate with high
bulk density and good flow characteristics. Typical materials are PA-fibres,
PET-flakes and scrap XPS-foams.

• The Shredder HR 62P is rounding off the product range of
shredders with a small compact shredder that might be interesting for
in-house plastics processing com- panies with only small quantities of lumps.
Due to its low acquisition costs and its compact design, this machine makes
an in-house recycling possible for blow moulding, film and injection

• The Granulator SML 45/60 SB with forced feeding (patent pending): this
special granulator design can considerably reduce its energy demand – with a
30 to 50 % lower connected load compared to a traditional machine.
Pre-shredded waste and hollow bodies can be recycled in a very economic way.
Some 200 machines of this design have already been sold since the market
Herbold Granulator SB series
In dialogue with the customer, HERBOLD MECKESHEIM will find the optimum
solution for customer’s recycling problem. Tests can be made in Herbold’s
technical centre where all the machines are available in production scale
size for tests with customer’s original material.
Our range of products

Herbold Meckesheim GmbH is a manufacturer of size reduction equipment for
the plastics industry. We are located in Meckesheim in southern Germany,
near the cities of Frankfurt/Main and Heidelberg. Our product suite consists
of machines and systems for the recycling of soft and semi-rigid materials
We have specialized in the recycling of scrap for the plastics industry, the
recycling of used and mixed post consumer or post industrial plastics, the
pulverization of plastics granules and regrind and many other applications
of our machines in the preparation of materials, resource recycling and
mechanical transforming in various industries.
We offer service and spare parts for our own machines as well as for many
other similar machines of all brands. We are 85 employees. The majority of
our customers are located in Germany, Europe, North America, North Africa,
in the Middle and the Far East. Our annual turnover amounts to approximately
30 Mio US$. Our Meckesheim production plant comprises about 4500 square
meters (= 48000 square feet).
The modular design of our machines, our constant stocks of common parts and
our flexible access to suppliers allow us to offer many of our machines and
recycling lines within very short delivery periods in spite of the wide
range and variety of our products.
For testing our machines with customer-specific materials there is a test
facility in Germany and another one in Smithfield, R.I.:
Impressive results with the HERBOLD plastcompactor when recycling plastic
BOPET and BOPP films with heavily printed surface or metallized cannot be
treated with traditional recycling processes, or at least only with great
difficulty due to the high standards required for the degasification of
Herbold succeeded in finding a reliable solution: the HERBOLD plastcompactor.
Thanks to its design as an “open” system, it can successfully cope with
entirely printed or metallized films.

Thin films with printed or metallized surface
Fig. 2: The end product: agglomerate with
high bulk density and excellent flow properties
The HERBOLD plastcompactor transforms film waste in agglomerate with
excellent flow properties and a very high bulk density that can then be
further processed on injection moulding machines or extrusion plants similar
to new material.
How does a HERBOLD plastcompactor work?
The material is continuously processed between a rotating and a stationary
compactor disc, equipped with screwed-on exchangeable kneading bars. The
pre-size-reduced material is continuously conveyed to the working zone
through the centre of the stationary disc. The friction arising at and
between the compactor discs very quickly heats the material, rendering it
Afterwards, the heated material is fed to a hot melt granulator, turning it
into agglomerate with good flow properties and a high bulk density.
The procedure is a particularly economic one and due to the automatic
operation of the HERBOLD plastcompactor, www.herbold.com, no operators are
needed. The densifier for plastics available in several sizes achieves a
throughput performance between 100 and 1.400 kg/h.
Herbold plastcompactor type HV 50
A typical representative of this size is the compactor HV 50 with a 110 kW
drive and a throughput performance of approximately 800 kg/h with A-PET or
PET-G. There is a positive side effect when processing PET film: the
material is crystallized at the same time.
Besides the treatment of uncontaminated waste, the HERBOLD plastcompactor
can also be used downstream of a washing line for contaminated waste: here
the material is dried at the same time, a process that can very easily and
effectively be achieved with very thin LLDPE films or with LLDPE stretch
