Guidetti’s low-noise cable recycler New pulveriser concept
from Herbold
Untha reveals latest four-shaft shredder
S+S belt systems for plastics recycling
Italian manufacturer Guidetti
has expanded its range of cable
recycling equipment with the
WIRE 315 – the smallest in this
series which incorporates a
number of enhancements not
seen in the larger models.
Weighing only 1200 kg, the plant is
claimed to be the quietest on today’s
global market thanks to a high level of
sound-proofi ng, and so can be used in any
area without inconveniencing staff or
other manufacturing processes. Its capac-
ity ranges from 200 to 300 kg per hour of
electrical and electronic copper cable.
The standard version comprises an auto-
matic feeding system from the shredder
and a forced dosing system to keep the
granulator’s efficiency constant. The
granulator is equipped with three rotat-
ing blades and two stationary blades. A
vibrating dry separator sorts the insula-
tion and copper content.
The WIRE 315 is completed by a de-
dusting and self-cleaning fi ltering sys-
tem which transports and collects the
dust generated in the process.

A new generation of pulverisers
from Herbold Meckesheim fea-
tures a vertical rotor shaft confi gu-
ration and a directly fl anged drive.
Furthermore, the discs are no longer
screwed in but clamped, thereby eliminat-
ing holes and reducing the risk of disc
breakage to a minimum, says the company.
The fi rst machine with this new design
to become available from Herbold is the
PU 650 with a disc diameter of 650 mm.
Pulverisers designed to handle plastics
are machines with a very high circumfer-
ential speed. Their bearings are particu-
larly robust and offer long service times
if there is mass balancing and no infl u-
ence of transverse forces, as is the case
with a V-belt drive. Its vertical confi gura-
tion is an optimal constructional advan-
tage for that, according to Herbold.
The horizontal configuration of the
grinding discs has a positive infl uence
on the dwell time of the material in the
grinding chamber, thus achieving a
greater fi neness with a high throughput.
Two grooved grinding discs work oppo-
site to each other to boost fi neness and
throughput. Re-feeding of coarse mate-
rial either becomes superfl uous or is
simplifi ed when compared to conven-
tional pulverisers, Herbold maintains.

Following a year-long develop-
ment phase and a series of
comprehensive tests, Untha has
launched its largest four-shaft
shredder to date.
The RS150 has been developed for
extreme applications where the require-
ment is not only for a high throughput
and availability but also for low operat-
ing costs.
The highlight of this innovation is the
newly-developed Untha Torque Drive
which is described as a dynamic and
energy-saving concept that ensures cut-
ting shafts are stopped immediately when
foreign materials enter the system in order
to prevent damage to the cutting tools.
Additionally, frequent reversing is pos-
sible with this drive set-up – an espe-
cially important facility, says the devel-
oper, when shredding problematic
materials. In contrast to high-speed sys-
tems (asynchronous motors), this par-
ticular drive works without wear parts
such as couplings, belts, shear bolts or
fl y wheels, thus minimising its suscepti-
bility to failures, according to Untha.
By varying the speed of rotation of the
cutting shafts, throughput can be adapt-
ed to the material that is to be shredded.
The RS150 series made its début at the
fi rst of Untha’s Recycling Days which
took place in Kuchl near Salzburg in
Austria from May 25 to 26.

The plastics industry continues
to struggle with rapidly-rising
raw material prices. As a result,
there is an increased pressure
to use recycled material and
rejected plastics in many pro-
duction processes.
However, this approach demands prop-
er recycling of the original plastic mate-
rials to produce secondary raw materials
of appropriate quality.
Detectors from S+S are designed to iden-
tify magnetic and non-magnetic metal
contaminants in a product in order to
prevent downstream damage. These
detectors and also S+S separators are
used both for in-house recycling and in
specialised recycling plants. By removing
metal, they enhance product quality as
well as reduce the costs associ-
ated with machinery damage
and factory downtime.
S+S has now added to its prod-
uct portfolio with
the intro-
duction of
the Plasti-
con series
of conveyor
belt systems
which are for use upstream of size-
reduction equipment such shredders or
granulators. To guarantee the greatest
sensitivity, these systems comply with
the needs of the latest metal detection
technology while their robust construc-
tion can cope with the rigorous demands
and conditions found in recycling plants.
Furthermore, the height of Plasticon
conveyor belts can be adjusted at both
ends to offer users more fl exibility.
