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.

ZSS Single Shaft 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.

ZXS Heavy Duty 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.
