The
recycling of scrap tires allows for the regeneration of valuable
materials such as rubber, steel and textile. PALLMANN offers
efficient and robust machines and systems for this application.
Shredders, knife mills, pulverizing systems and conveying
technology cover the complete spectrum of the necessary size
reduction technology.
The amount of scrap tires is
growing worldwide and therefore the necessity to recycle is
increasing. Scrap tire recycling, as it is commonly known, means
not only the replacement of fossil fuels but also the separation
of valuable materials such as rubber, steel and textiles and to
reintroduce them into the raw material cycle.
A lot can be retrieved from
scrap tires by means of clever recycling, i.e. granules in many
different sizes, textile wool as well as cleanly separated
steel. By using the correct technology, the recycling of scrap
tires is nowadays profitable and is developing into an
attractive business field.
Three-step
processing
The three-step PALLMANN-process
consists of shredding of the scrap tires, loosening and
separating of the rubber-steel-textile composite as well as
pulverizing of the rubber granules. For this application,
PALLMANN offers complete recycling systems from one source.
To start the recycling process,
scrap tires have to be precut into chunks; high capacity
shredders with hydraulic drives, type "LION" are used for this
application. These high capacity machines produce clean cut
chunks, size 50 x 50 mm, a preferred and easy to dose bulk
material for thermal reuse in a rotary kiln of a cement factory
(TDF - Tire Derived Fuel). The scrap tires are cut to chunk
sizes, 150 x 150 mm, as feed material for a granulation step for
the production of rubber granules. This is the ideal size to
separate the tire components rubber, textile and steel in an
additional preparation step.
After the pre-cutting process
with the shredder, type "LION", the "TIGER" loosens the
rubber-steel-textile compound. The loosened components are
separated by means of magnetic- and screening technology. A
mixed fraction is introduced into the "TIGER". Textile fibers
and steel cord make up for approximately 30 percent of the
weight of a tire. The textile fluff is very well suited as
insulation material. The separated steel wires have a purity of
> 97 percent and can be lucratively sold.
The rubber granules are, in a
third step, granulated in the "PANTHER" to desired particle size
and are further freed from steel and textile. Granule purities
of 99,99 percent, freed from steel wire and 99,9 percent, freed
from textile fluff, can be achieved.
Typical areas of application for
rubber granules from scrap tires are the construction of running
tracks and tennis courts in sports arenas, flexible flooring for
improved protection from falling on playgrounds, in road
construction as an additive to asphalt, for decreasing ruts and
road noise, for the production of molded parts for industries
and households, the production of mats for heat-, noise- and
vibration damping in vehicles and at workstations etc.
