Tens of millions tire disposal every year globally. Disposal of waste tire is challenging task because tires have long life and non-biodegradable.

The traditional method of waste tire management dumping tires into soil or landfilling are short term vision and investment.

To reduce scrap tires worldwide we need to recycle tires to make the solution for waste management.

The scrap tires can be recycled by two methods Ambient mechanical grinding and cryogenic method.

We use the ambient mechanical grinding method.

In ambient mechanical grinding process, the breaking up of a scrap tire happens at or above normal room temperature. Ambient grinding is a multi-step technology and uses whole or pre-treated car or truck tires in the form of shred or chips, or sidewalls or treads. The rubbers, metals and textiles are sequentially separated out. Tires are passed through a shredder, which breaks the tires into chips.

The chips are fed into a granulator that breaks them into small pieces while removing steel and fiber in the process. Any remaining steel is removed magnetically and fiber through a combination of shaking screens and wind sifters. Finer rubber particles can be obtained through further grinding in secondary granulators and high-speed rotary mills.

Ambient grinding is the production process used by the majority of crumb producers. The machines most commonly used for fine grinding in ambient plants are:

• Secondary granulators
• High speed rotary mills
• Extruders or screw presses
• Cracker mills
