Double-Shaft Shredder GDT Series

Double-Shaft Shredder GDT Series

GDT series shredder is a dual-shaft shredder specially designed to shred waste tires economically. It has high shear and is equipped with a customized trommel. GEP Ecotech's GDT Shredder can work alone, shredding the entire tire to the target size, and is widely used in small applications such as rubber recycling, pyrolyzing, or making tire-derived fuel(TDF).


The so-called scrap tires refer to tires that have been replaced or eliminated and have lost their value as tires, as well as the end-of-life tires generated by factories. Scrap tires have a high recycling value, the output of fuel oil, carbon black, steel wire, rubber powder and other renewable resources, can create considerable economic benefits.

Working Principle

The tire shredder is designed with the structure of shredder and ring roller screen in one. When the tire enters the shredding chamber, it is sheared and torn by the relative rotating cutters, and then falls onto the rotating ring roller screen. The material that passes through the screen holes falls off directly, while the material that does not pass through the screen holes is brought back to the shredding chamber and is repeatedly sheared by the cutters until it passes through the screen holes.

Double-Shaft Shredder GDT Series

The GDT series shredder is a twin-shaft shearing type shredder developed by GEP Ecotech CO., LTD specifically for a wide range of waste tires. The shearing and tearing action of the shredder enables the tires to be shredded to the size required for subsequent recycling processes such as oil cracking, cement kiln incineration, tire grinding and so on, thus unlocking the potential value of waste tires and turning them into real "black gold".

GDT series double-shaft shredder has high shredding efficiency, high output, low energy consumption, and can easily cope with car tires & truck tires, diagonal tires & radial tires, pneumatic tires & solid tires, small car tires ≤ 800mm & large car tires ≥ 900mm, etc. We can also configure supporting equipment such as hydraulic tire wire pulling machine, steel wire separator, rubber breaker, screening machine, granulator, fibre separator, etc. to improve the recycling efficiency.

Extended Information

  1. Equipment Price and Terms of Delivery?

    GEP Ecotech conducts business around the world, the delivery price of equipment changes frequently and is affected by multiple factors, including the price of raw materials, the delivery location, and the specific configuration of the equipment. You can inform us of your specific needs by filling in the form in our website or contacting our online service. We will send you the latest quotation after receiving your request.
  2. What kind of equipment does the waste tire processing line consist of?

    The main equipment is the GDT tire shredder, other equipment include: GRT series tire wire drawing machine, GPT series rubber breaker, GFT series steel wire separator, GVF series uniform feeder, GFS series fiber separator, GZT series granulator. GEP can not only provide you with a full set of equipment for the waste tire treatment line, but also customize a reasonable solution to help you succeed!
  3. How are tires turned into rubber powder by the shredder?

    (1) tire shredded into pieces: the whole tire cannot be directly turned into rubber powder, it is a gradual process of becoming smaller, the so-called shredded pieces need to be involved in the GDT tire shredder, gradually shear the waste tire into smaller pieces; (2) separation of impurities in the tire: the composition of the tire is not only rubber, there are also fibers and steel wires, since the tire powder is a pure rubber powder, then it is necessary to gradually strip the fibers and steel wires The process of stripping is actually also the process of gradually making the tire smaller, which requires the use of GEP's steel wire separator, fiber separator and self-unloading iron removal system; (3) tire grinding: after the completion of the tire homogenization of fine particles broken, it is necessary to choose different tire grinding machines to grind according to the mesh of the tire rubber powder.
  4. What are the unique advantages of GEP shredder cutter?

    Cutters are forged with high-quality wear-resistant materials which are imported from Europe. All cutters are hot processed by advanced heat treatment technology and then processed by high precision machining, with long service life. The fixed cutter can be disassembled and installed independently, and the disassembly and replacement can be completed quickly in a short time. GEP can customize suitable cutters according to customer needs, effectively ensuring the maximum performance of cutters.
  5. In what ways the intelligentialize of GEP shredder are reflected?

    GEP shredder adopts patented intelligent technology for automatic control, which realizes intelligent detection, intelligent protection, intelligent maintenance and automatic weighing. It can predict and alarm equipment failure in advance. Intelligent system can centralize shredder process control, adjust shredder operation parameters according to actual production needs, reduce the failure rate effectively , improve production continuity and reduce maintenance costs effectively.
