hamos line produces clean ABS and PS from electronic scrap
Easily separate black plastics
ABS-PS separation at Elektro Recycling, spol. s.r.o:
The company Elektro
Recycling, the largest Slovakian electronics scrap recycler, has recently
started up a large line to process mixed plastics from electronics scrap. The
core of the line is an electrostatic separation line from hamos for plastic
separation: after several pre-treatment stages such as shredding, removal of
foreign particles and float-and-sink separation, the hamos KRS electrostatic
plastics recycling line is used for production of high grade ABS and PS
with electrostatic separation
float-and-sink line separates all undesired plastics, including flame retardant
materials, producing a mixture of ABS and PS as a good fraction. The hamos KRS
downstream electrostatic separation line then separates this plastic mixture
into individual pure ABS and PS fractions.
Peter Matula, Plant
Manager at Elektro Recycling says of this:
electrostatic separation line, we now produce clean PS and ABS fractions, which
we then compound. Our end customers are enthusiastic about the high quality of
our ABS and PS granulates. It is very important for us that we can also easily
separate black plastics”.
At Elektro Recycling,
the mixed ground material with particle size < 10 mm is separated in a
2-stage electrostatic separation process. Clean ABS is produced in the first
stage, clean PS in the second stage. It
has also been managed to separate out even undesired PP content. Elektro
Recycling processes around 3 tonnes per hour in the plastics recycling line
into high-grade regranulate.
Separation of black plastics
Mixed plastics from
electronics scrap consist of 60 – 80 % black plastics. For this reason, sorting
processes such as near infrared are of limited use in processing such mixtures.
Only a small percentage of good product can be separated with these other
processes, while the main proportion cannot be separated, on account of the
The ideal processing
method for electronic scrap plastics is therefore electrostatic separation, as
electrostatic separators work irrespective of colour, specific gravity and
shape of the particles.
of electrostatic separation
tribo-electric process is used in electrostatic separation of mixed plastics.
The different plastics become differently charged through intensive particle
contact in a special electric charging unit – one plastic acquires a positive
charge, another plastic a negative charge. The plastics can be subsequently
separated into individual fractions with the aid of high voltage electrodes.
