Our Modular Concept
Collecting the dust from all modules and leading them through a piping to a filter-system to separate the dust from air. This keeps the material and the working environment clean, to reach a good output quality and a healthy working environment.
Goods receipt / sorting Floor
Quality assurance and transparency of material flow start here with the precise recording of weights when the goods are received. Large machines are removed from the flow of material.
Processing of the electronic scrap starts immediately on receipt of the goods. Complete loads and bulk material are weighed on the outdoor vehicle weighbridge. Packaged deliveries are recorded and weighed on the indoor vehicle weighbridge, assessed and then subjected to preliminary sorting. Both weighbridges are directly linked to our computer system. At the customer’s request, we are able to evaluate incoming deliveries. The material is sorted in accordance with the customer’s instructions and weighed using computer-aided platforms and belt weighing machines. This procedure ensures that the sorting criteria are met.
Material is lead in the crusher. The cartridges are opened up during the shredding process. Inertisation powder is lead into the shredder and mixed with the cartridges to prevent explosions. In the event of an explosion, a secondary explosion-protection system is installed to ensure the safety of workers and equipment. After shredding the cartridges, the powder will be separated. The remaining material is further processed in module 3.
Preliminary breaking down
Breaking the material down into small pieces by a shredder, followed by separation into the fractions. Batteries and capacitors are separated from the process.
The rotating shredder breaks up electronic devices. The effect of the blows applied and of the items colliding with each other lead to the component parts of the equipment breaking off at the weakest points. For example, steel shafts are no longer cut up, but are only bent and torn from their mountings. Batteries and capacitors lose adhesion at the clamping or solder points. After being pulled out, the small parts are no longer able to absorb energy and can therefore leave the grinding room directly.
Large sheet-metal parts which do not pass through the outlet are processed further until they reach the size of the gap fitted.
Harmful substances and recyclable materials are separated out by means of magnetic separators, sieves, cyclone separators and manual sorting.
The dedusted material is separated into the >100 and <100 fractions by means of a fork-sieve.
Subsequent magnets, manual-sorting positions and cyclone separators ensure removal of harmful substances (batteries, capacitors) as well as separation of iron, aluminum, heavy metal and circuit-board fractions. The residual material is then again broken down and freed from dust.
The fractions in which the harmful substances have been concentrated are manually sorted out.
The fractions containing harmful substances which arrived from the mechanical sorting stages are sorted out manually via a silo with a dispensing delivery channel and a conveyor belt. In the process, recyclable materials such as brass, chrome-nickel steel and copper-iron are also picked out along with the harmful substances (batteries, capacitors).
Extraction of plastics
None Ferrous, Mixed plastics and or PCB Boards is separated through none ferrous – and sensor system, which lead the plastic to Module 5.
The material broken down and reduced to pellets by the impact crusher is separated into metals and non-metals by means of separating tables.
The impact crusher consists of rotating hammers which accelerate the broken-down material. The particles are decelerated again at the grinding plates placed around the perimeter. Metals are thereby deformed and plastics are broken into small pieces. After several circuits, the material to be ground is fully processed. Subsequent sieving creates the necessary pre-condition for successful metal-plastic separation on density separation tables.
Plastic / Plastic Separation
Flame retardant material is separated through a swim float system, the target plastics are led to a separation system, which separates ABS, PS, PP, PE and PC. This material has the highest quality to resell to the market.
Refrigerator and Air conditioners
The cooling circling system is drilled and the oil and gases: R12, R22, R502, R134a, R600a, are sucked-off and filled into transporting bottles (Stage 1 of Module 6).
In stage 2 the rest of material is shredded and with a separation system, ferrous, none ferrous and plastics are separated. The whole system collects the gases.
The printed circuits feed to the shredder and crushed. Magnetic Separator / Eddy Current separates ferrous and none ferrous material out. The following mill crushes the boards to disintegrate the material for further separation. Screen machines prepare the material for the air separator. The air separators separate the plastics from the none ferrous. The electric static system separates the precious metals from dust.
Cables are fed to the pre-shredder and cut to smaller pieces. In the following granulator and mill cables are disintegrated and ready for separation. In the following separation process copper gets separated from plastic, dust and ferrous metals.
Knowledge Transfer, Education & Service (KES)
All service contracts are individual designed for a project and have to be developed. Nevertheless, we believe in continuous support and long partnership in order to create a successful business. We strongly recommend therefore to analyze which service contracts are needed.
After handing over the plant regular inspections are required to run a smooth production and prolong the lifetime of the plant. For that matter the customer can enter an inspection agreement, where weeeSwiss leads this inspection in order to train the customer to a higher level.
Ramp-up Production support
During the initial production time it is helpful to have weeeSwiss at site to support the ramp-up production. Recycling process experts are placed at the plant to support and improve the production process.
weeeSwiss offers trainings for operators and maintenace personnel. These trainings can be conducted at weeeSwiss in Switzerland or at the customer’s desired location.
Sales of Output Materials
Over many years, weeeSwiss has created a large network in the recycling business. We know where to sell the Output Materials for the best price. Therefore, we offer our customers to participate in this network and let them benefit from it. As we know what quality our plants deliver, we can easily integrate your output materials in our existing contracts.
