Millions of tyres are produced every year all over the world and demand is still growing. However, one of the problems that have to be dealt with is how to deal with the tyres that have been mechanically damaged or have reached the end of their usable life. The solution is an environmentally friendly recycling process that makes use of equipment like tyre shredders and granulators.
The largest and most modern tyre recycling plant in Europe can be found at Asamer Holding’s tyre recycling facilities in the upper Austrian town of Gmunden. The recycling facility covers an operating area of 20,000 square meters with the capability to process 40,000 tonnes of scrap tyres every year in the most economic and eco-friendly process.
Recycling is a three-process operation that starts with the pre-shredding of car, truck and tractor tyres into strip-like pieces that measure 100mm by 150mm. A conveyor is used to feed two large bunkers with a total volume of 2000 m3 where the pre-shredded truck and car tyres will be stored and temporarily separated from each other.
The second process occurs in the granulating lines where the end product is largely textile and steel-free rubber granulates that measure less than 3mm in size. Most high-value products of different manufacturers are made from the rubber granulates produced from the second process. Products include sport field building like track surface construction, noise barriers, floor surfacing for schools and industrial construction.
Since some applications require rubber granules in the range of 0.6 to 4mm (5-30 mesh) ambient grinding plants perform a number of consecutive steps to generate finely grinded rubber particle sizes. Secondary granulators with high-speed rotary mill extruders or screw presses cracker mills is the technology used to produce relatively coarse rubber materials. However, process that is also called cryogenic grinding technology requires less energy than ambient technology.
Heavy duty tyre shredder for sale is designed for demanding and high throughput applications in the recycling industry. Input materials include rubber tyres, fridges, purges, pallets, bales, drums and barrels including pipes and films. The main focus of the tyre shredders is to shred tyres into smaller pieces or profiles for the manufacture of products.
