Otr tire disposal:reuse process flow

Waste tyres, as solid waste, pose serious environmental pollution if not properly disposed of. However, these waste tyres also contain enormous resource value.

In order to promote sustainable development and reduce environmental pollution, the recycling process of waste tyres has emerged.

Tyre Pretreatment

The first step in recycling waste tyres is collection and classification. Waste tyres vary widely in type, size, and degree of wear, so they need to be classified according to these factors.

Steel Wire Separation

One of the main components of waste tyres is rubber, but they also contain a large amount of steel wire. In order to improve subsequent processing efficiency and the purity of rubber, the separation of steel wire is crucial. Steel wire separators usually use methods such as rotation, vibration, or magnetic separation to separate rubber particles from steel wire.

Rubber Crushing

After steel wire separation, the remaining rubber particles are usually large and need further crushing. Rubber breakers and grinders are commonly used equipment for this step. During the crushing process, the fineness of the rubber particles can be controlled by adjusting the rotational speed and mesh aperture of the sieve. Temperature control is also important during the crushing process to avoid overheating, which may affect the subsequent regeneration performance of the rubber.

Rubber Regeneration

Crushed rubber particles usually require regeneration treatment to restore their properties. Common regeneration methods include pyrolysis regeneration and chemical regeneration. Pyrolysis regeneration involves decomposing rubber at high temperatures to produce oil, gas, and carbon black as by-products, which can also be further utilized.

Product Application

Regenerated rubber can be used to manufacture various rubber products such as new tyres, rubber sheets, and rubber pipes. At the same time, regenerated rubber can also be used as a filler or modifier in the production of other materials to enhance their properties and reduce costs.
