The Rasper is a key machine in tire recycling for separating embedded steel wires from rubber chips. It ensures high-purity rubber output, protects downstream equipment from damage, and allows the separated steel to be recycled, enhancing overall process efficiency and value.
With the rapid increase in vehicle ownership, the number of waste tires generated continues to rise. Without proper recycling, these tires create storage and transportation challenges, waste the valuable steel wires inside, and increase environmental pressure. Efficient resource recovery is therefore essential to transform waste tires from an environmental concern into valuable materials.Unlocking the Resource Potential of Waste TiresWaste tires are not just scrap—they contain two key recyclable components: steel wires and rubber. Through GEP ECOTECH's advanced recycling process:Steel Wire Recovery: Steel wires are efficiently separated and collected, providing high-quality material for the metal recycling industry and reducing reliance on virgin steel.Rubber Granules Production: Tire chips are simultaneously processed into uniform rubber granules as the steel wires are separated, suitable for applications such as road paving, sports surfaces, and rubber product manufacturing.GEP ECOTECH Recycling
The Tyre Rasper is composed of a motor, reducer, rotating cutter roller, chamber, frame, screen, and hydraulic auxiliary system. It is designed to shred pre-processed waste tire rubber blocks (50-80 mm) into fine rubber granules of 9-16 mm, while efficiently separating steel wires and part of the fibers during the shredding process. With a compact structure, low energy consumption, and stable performance, it serves as a key piece of equipment in fine rubber recycling systems at any modern Tire Recycling Plant.The machine adopts an intermeshing serrated blade design, where the rotating blades work in combination with stationary blades inside the housing to apply strong shearing and tearing forces to the rubber blocks. This dual-action process ensures rapid size reduction and effective separation of embedded steel wires and fibers. A screen is mounted at the bottom of the chamber—materials smaller than the screen holes are discharged, while oversized pieces remain for further shredding until they meet the
In the process of waste tire recycling, the complete separation of rubber and steel wire directly impacts the purity of the output and the efficiency of downstream processing. As a leading solid waste treatment technology company, GEP ECOTECH has developed a high-performance tire steel wire separator to provide efficient, stable, and eco-friendly solutions for mid-stage tire processing. It has earned the trust of many recycling enterprises.DefinitionThe tire steel wire separator, also known as Tyre Rasper, is an essential piece of equipment in waste tire recycling lines. It is used to deeply separate embedded fine steel wires from mid-sized rubber granules (typically 50–80 mm in size) after initial shredding. This improves rubber purity and the overall value of recycled materials.Why It Is NecessaryWaste tires contain a large amount of embedded steel wires. If not properly separated, these wires can:Reduce the quality of rubber granules or powderCause wear or damage to granulators and milling machinesIncreas
