Features
① Segmented Temperature-controlled Pyrolysis Process with High Oil Conversion Rate
Waste Tyre Thermal Decomposition Plant adopts multi-zone segmented temperature-control technology. Low-temperature zone completes dehydration and softening of tyres; medium-temperature zone breaks rubber molecular chains for oil production; high-temperature zone realizes deep decomposition of residual carbon. Compared with single-constant-temperature pyrolysis, segmented temperature control increases pyrolysis oil yield by 5%-8%, reduces heavy-oil fractions, and produces pyrolysis oil with lighter color and higher calorific value.
② Steel Wire Separation & Discharge Device
After pyrolysis, residual steel wire and carbon black inside the reactor are separated by a special screw discharger. Steel wire is bundled neatly while carbon black is collected in closed mode, making subsequent manual slag-cleaning inside reactor convenient.
③ Fully-closed Negative-pressure Flue-gas Collection System
Waste Tyre Thermal Decomposition Plant runs under slight negative pressure. Flue-gas collecting hoods are installed at all potential leakage points including feeding port, discharging port and reactor door. Leaked oil-gas and dust are extracted in real time and sent to combustion chamber for incineration. Combined with desulfurization and dust-removal tower, the final flue-gas concentrations of particulate matter, SO₂ and NOₓ are far below national standard limits. The equipment can operate legally near residential areas.
④ Optional Pyrolysis Oil Refining Module
The equipment can be equipped with oil-water separation and oil refining module. Dehydration, slag removal and light-component enrichment are completed simultaneously during pyrolysis-oil condensation and collection. The output oil can be directly sold as fuel for industrial boilers without further post-treatment, shortening the conversion chain from raw materials to commercial products.
Advantages
① Full Resource Recovery of Products with Zero Solid-waste Discharge
All four products from tyre pyrolysis are recyclable. Pyrolysis oil can be used as industrial fuel or further refined into diesel oil; carbon black can be deep-processed into rubber reinforcing agent or carbon-black pellets; steel wire can be sold directly; combustible gas is recycled for combustion to realize energy self-supply. No secondary solid waste is generated in the whole process, realizing full utilization of waste tyres.
② High Energy Self-sufficiency & Low Operating Cost
Purified combustible gas generated from pyrolysis is fully delivered back to combustion chamber as heating fuel. No extra diesel, natural gas or coal is required during normal operation, achieving over 85% energy self-sufficiency.
③ Wide Compatibility for Various Tyre Specifications and Strong Raw-material Adaptability
The equipment can directly process various rubber-containing wastes such as tyre chunks, tyre rubber powder, inner tubes and conveyor belts. The large-diameter reactor door allows direct feeding of off-the-road tyres below 1000 mm diameter without tyre shredder, lowering upfront project investment.
Application Scenarios
Waste Tyre Thermal Decomposition Plant applies to the following business scenarios:
Waste Tyre Recycling & Processing Enterprises: As the end-disposal link of tyre recycling chain, it converts waste passenger-car tyres, truck tyres and off-the-road tyres into pyrolysis oil, carbon black and steel wire to extend industrial chain and improve added value of products.
Disposal of Trim Waste from Tyre Manufacturers: Treat production wastes such as waste rubber materials, defective tyres and trimmings from tyre factories. It relieves enterprises' pressure of environmental-protection disposal, and recycled pyrolysis oil can be used for factory boilers to cut energy procurement costs.
Regional Solid-waste Disposal Centers: Provide centralized waste-tyre disposal services for prefecture-level or county-level regions. Operate via government franchise or BOT model to gain dual benefits from disposal fees and sales of pyrolysis products.
Co-disposal for Rubber-product Factory Wastes: Process various waste rubber products such as rubber hoses, rubber belts and rubber shoes. Mixed pyrolysis with waste tyres expands raw-material sources and improves equipment utilization rate.

Production Process Flow
- Raw-material Acceptance & Temporary Storage: Inspect recycled waste tyres to remove impurities, classify and store in rain-proof raw-material warehouse for reactor feeding.
- Feeding into Reactor: Feed whole tyres or tyre chunks into reactor through large-diameter door by hydraulic feeder or forklift. Close reactor door and fasten with bolts for tight sealing.
- Segmented Temperature-controlled Pyrolysis: Ignite combustion chamber for heating. The rotating reactor heats up section-by-section per preset program: low-temperature zone (150-250℃) for dehydration & softening; medium-temperature zone (250-400℃) for rubber-chain cracking and oil generation; high-temperature zone (400-500℃) for deep decomposition of residual carbon.
- Oil-gas Condensation: Pyrolysis-generated oil-gas flows into multi-stage condensation system via pipelines. Fast heat exchange and liquefaction are realized by forced circulating water cooling. Liquid pyrolysis oil flows into oil storage tank; non-condensable gas enters gas-purification system.
- Combustible-gas Recycling for Heating: Purified combustible gas passes through flame arrester and is delivered to combustion chamber as heating fuel to replace external energy and realize self-sufficient energy supply.
- Cooling & Discharging: Stop heating after pyrolysis. The reactor keeps rotating for accelerated cooling. When reactor temperature drops to safe range, carbon black and steel wire are discharged by screw discharger and collected separately.
- Optional Product Deep Processing: Pyrolysis oil can be sent to distillation equipment for diesel production; carbon black is processed into commercial carbon black via magnetic separation, grinding and pelletizing; steel wire is baled and delivered to steel mills for remelting.
- Flue-gas Purification & Discharge: Flue gas from combustion chamber undergoes deep treatment by desulfurization tower, dust collector and denitrification unit. Qualified flue gas is discharged through high-altitude chimney with zero black smoke and no peculiar odor in the whole process.
