Machines and Systems for the Recycling of Scrap Tires

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.
