e-Waste Recycling |
Overview |
In light of the raw material prices for precious
metals as well as plastics all types of
electronic waste recycling have become more and
more important lately.
Talking about e-waste we
mostly refer to ‘white goods’. Used home
appliances such as fridges, washing machine,
coffee makers and so on.
These products
generally contain high value plastics and
precious metals, in most countries they are
collected separately or taken back by producers
and dealers. But another important part of
electronic waste recycling is recycling of all
sorts of cables. |
Typical challenges in
recycling |
ZERMA offers a wide range of machines well
suited for electronic waste recycling. Generally
the recycling process starts by dismantling
large parts like compressors or transformers.
Then the whole product is shred in ZXS or ZSS
single shaft shredders, after this step a rough
separation of plastics, metals and other
materials is possible. The materials are then
further reduced in hammer mills and granulators,
to achieve a finer separation.
As the whole process of separating and
classifying the materials is very complex and
includes specialized equipment we generally work
with system integrators and engineering
companies to provide them with high quality size
reduction components to be integrated into their
systems.
In the case of cable recycling, the complete
cables are first shred to a size of about 30 cm
in a ZSS or ZXS shredder and then ground down to
their final size of 3mm in a GSH heavy duty
granulator. This size allows for the best
separation of metal and plastic on our
separation tables. The separation tables split
the plastic and metallic factions in a process
involving both movement and airflow.
Furthermore our machines are used by
producers of electronic parts and components to
destroy sensitive media, faulty products or
prototypes. In these cases just a shredder or a
combination of shredder and granulator is used
depending on the required final size. |

ZBS Small Lump
Shredders |
The ZBS shredders have been designed for in house
recycling of small lumps and purges from injection and
blow moulding processes. The typical input materials are
small and medium sized cakes such as head waste. The
material can be shred to reduce the volume or processed
further in a granulator to be re introduced into the
production process immediately. |

Shredders |
The ZSS shredders have been designed for a wide array of
applications and industries such as in house and general
recycling, electronic waste and post consumer waste
handling with a wide variety of input materials.
Depending on input material and the following process
the shredded material can be used directly or go into
the next step of size reduction for example in a GSH
granulator. |

Shredders |
The ZXS shredders have been designed for the most
demanding and high throughput applications in recycling
industries. The input materials can be all kinds of
plastics, wood, paper, cardboard, e-waste, post consumer
waste, rubber, etc. in various shapes and sizes. Typical
input materials are: fridges, purges, tires, pallets,
bales, drums and barrels, pipes, film and so on… |

ZTTS Tyre Shredders |
The ZTTS is
used to pre shred complete car tyres or large
chunks of pre processed tires down to a size of
about 150 mm. The twin rows of stator knives and
screen in the ZTTS enable it to take the tyre
shreds down to a any required size > 20 mm. The
unique machine design combined with the variable
cutting gap create an optimal separation of
rubber and steel fractions. |

ZHM Hammer Mills |
The main purpose for the ZERMA ZHM hammer mill
is the processing of electronic waste, such as
whole computers, white goods and ICBs. The main
advantage in these processes lies in its
insensitivity to contamination and abrasive
materials while being able to achieve a rather
small output material. Through the high degree
of disintegration it is possible to achieve good
separation results in the following processes. |
