WEEE recycling line |
|
Hangzhou Fuxing Group Co., China, uses mechanical recycling
principles in its waste electrical & electronic equipment (WEEE)
recycling technology. The plant can easily and rapidly process
mono streams of different types of material, such as shredded
refrigerators, computers or household appliances.
The plant consists of washers, spinners, granulators,
ballistic separators, air and double water shaking tables, and
metal separation systems. The WEEE material is fed into a
bunker with a vibrating conveyor, which delivers the materials
through a metal separation system (ballistic separator) to the
granulator. After the grinding step, the material goes to the
air-sifter where dust and other light contamination are
removed. A washing and separation step follows in the double
water shaking table, where metals, glass and special plastics
like flame retardants are separated. A screw conveyor then
transports the material to the spinner where the flakes get
dried. Finally, an air shaking table removes dust and very
small particles.
The recycling process has a closed water circuit and a closed
air and dust system, which results in low waste disposal
costs. Turnkey, customized plants can be delivered to suit
different material types as well as processing capacities.

Process to separate lead from glass |
|
Two entrepreneurs from Manchester, the United Kingdom – Mr.
Simon Greer and Mr. Clive Maudsley – have developed a new kind
of electric furnace to reclaim pure lead from television
glass. Nulife Glass Ltd., their new company, is now ready to
start selling furnaces for processing the glass from up to
1,000 cathode ray tubes (CRTs) a day. The process can recover
more than 95 per cent of the lead in the crushed glass from
the CRTs of television sets and computer monitors.
The lead content in CRT glass can be as high as 20 per cent,
with a single 34-inch television containing as much as 1 kg of
the metal as lead oxide. Mr. Greer said that the Nulife
Glass furnace produces two usable products in a process that
involves the passing of electric current through the molten
CRT glass, permitting the lead to separate out from the glass
matrix in its pure, metallic form. The molten lead and the
glass are then tapped off from separate fractions.

Implosion and X-rays for CRT recycling |
|
MDJ Light Brothers, the recycling firm in the United Kingdom,
has set up an industrial ‘imploder’ to break up glass from
CRTs and an X-ray sorting system to separate funnel glass from
screen glass. The company believes its system, installed in
its new CRT processing facility, can ultimately achieve a
materials recovery rate above 90 per cent by weight, sorting
around 15,000 t of CRT glass each year.
The system involves first manually dismantling televisions and
monitors to separate the CRT from other components, including
plastic and copper parts, and the electron gun. CRTs are then
fed into a Krysteline GP15 imploder, which sends a sudden
burst of energy into the glass to effectively shatter it. The
machine is based on the same principle in which high musical
notes shatter wine glasses, and can process 30 tph of
material. The resulting grains have no sharps, and can vary in
size from 400 µm to 15 cm.
To separate the leaded funnel glass from the higher-value
screen glass, the company is using a Varicon-X machine from
the German manufacturers S+S GmbH. The machine identifies the
different types of glass based on different X-ray absorption
rates, and instructs the separation system to direct the
various glass grains into the appropriate hoppers.
