Comparison Between Old and New Devulcanizing System





Maxlink’s new thermo-mechanical devulcanizing technology, using the patented continuous screw devulcanizer operating at atmospheric pressure, consumes less energy, and is much safer and eco-friendly because the process does not require high pressure or steam, hence no waste water is discharged and little fumes emitted. Rubber reclaiming plant using this equipment would meet the most stringent environmental requirements.

High Pressure Dynamic Devulcanizer (Old System)Continuous Screw Devulcanizer (New System)
High pressure – 2 to 4 MPa (20 – 40 Bar)
High temperature – 220°to 300°C
Operates at atmospheric pressure
Pressure vessel safety inspections not required
Meets all standard safety requirements
Steam heating – 2 ton/hour
Boiler required – 800 Kcal
Thermal heating (hot) oil or electromagnetic induction used
No boiler required
Water used in process.
To produce 1 ton of rubber, 250 litres of water is required, and
hence 250 litres of effluent is discharged
No water is discharged to pollute environment
Devulcanizing – 3 hour/batch
Loading and unloading – 3 hour/batch
3 – 4 operators required for process
Continuous feeding of raw materials
Only 1 operator required for fully automatic line,
saving labour cost
Production capacity – 3.5 to 4 ton/dayProduction capacity – up to 8 ton/day
Output doubled
Power consumption – 230 to 260 kw/tonPower consumption – 20 to 30% lower energy consumption
End products still at high temperature, and
may burn during storage
End products cooled to less than 60°C – no fire risk

The above comparison is based on equivalent production capacity of 6 m³ for each system.
