We can customize metal crushing and recycling production line for you.
The pyrolytic steel wire shredding and recycling line is an integrated, automated industrial equipment system. It primarily targets waste tire steel wire (containing residual rubber, carbon black, and other impurities) after pyrolysis treatment or steel wire materials with pyrolysis byproducts. Through a continuous process of shredding pretreatment, crushing and purification, sorting and separation, and dust removal and purification, this dedicated production line achieves efficient steel wire resource recovery and harmless impurity treatment. Its core goal is to address the high impurity content and recycling difficulties of pyrolytic steel wire, while also preventing environmental pollution from dust and harmful gases during the processing process. This dual-function system combines resource recycling with environmental protection.
The process flow of the pyrolytic steel wire shredding and washing line is as follows:
1. Feeding and Preliminary Shredding (Pretreatment Stage):
The pyrolytic steel wire material (often in lumpy or tangled form, containing 10%-20% residual rubber/carbon black) is fed at a uniform speed via a belt conveyor to a dual-shaft shredder. The shredder's two high-speed rotating shafts drive alloy cutters to shear and tear the material, breaking it into short steel wire segments (5-15 cm) and initially loosening surface impurities to prepare for subsequent deep crushing.
2. Deep Crushing and Impurity Stripping (Crushing Stage):
The shredded short steel wire segments are conveyed via a conveyor to a hammer crusher (or roller crusher). High-speed rotating hammers (or squeeze rollers) inside the crusher repeatedly strike and squeeze the steel wire, completely stripping away any residual rubber and carbon black adhering to the wire surface. This results in a mixture of steel wire segments, rubber chips, and carbon black powder. Simultaneously, the steel wire segments are further broken down into uniform lengths of 1-3 cm for subsequent sorting.
3. Steel Wire Sorting and Purity Enhancement (Sorting Stage):
The mixed material first enters a vibrating screen, where the varying mesh sizes preliminarily separate the smaller carbon black powder and rubber crumbs from the steel wire segments. (The carbon black powder can be collected and reused as fuel or filler.) The steel wire segments, which contain a small amount of light impurities, then enter a magnetic separator. This separator uses a strong magnetic field to attract the steel wire and completely separate it from the non-magnetic rubber crumbs and dust. Finally, the separated steel wire segments pass through an air separator, where airflow removes any remaining light dust from the surface, resulting in recycled steel wire with a purity of ≥95%.
4. Dust and Exhaust Gas Purification (Environmental Protection Stage):
Dust generated during the shredding, crushing, and sorting processes on the production line is collected through a "hood + duct" system and then fed into a pulse bag dust collector. Filter bags within the dust collector capture the dust, and the purified air (dust concentration ≤ 10mg/m³) meets emission standards. The collected dust can be recycled as a carbon black byproduct.
Whole waste tire machine/fragments: tire blocks, tire rims (including high-hardness steel wire rims), sidewalls, etc. that have not been cracked.
Pyrolysis tire steel wire: the remaining steel wire and rubber mixed mass after the waste tire is thermally cracked or physically crushed, and the steel wire is in a tangled or bonded state.
Tire steel wire waste: separately recycled tire steel wire bundles, steel cords (such as steel cords in radial tires), or other rubber product waste containing steel wire (such as steel wire hoses, conveyor belt scraps).
Other similar materials: metal-rubber composite materials with hardness and toughness close to tire steel wire, such as seals and shock absorbers containing steel wire, but the tool configuration needs to be adjusted according to the equipment specifications.
Core Advantages:
High Steel Wire Recovery Rate: Through the combined "shredding + crushing + magnetic separation" process, the steel wire recovery rate reaches over 98%, significantly higher than the 60%-70% achieved by manual sorting.
High Steel Wire Purity: The recovered steel wire has a purity of ≥95% and can be directly sent to steel mills for scrap smelting, eliminating the need for secondary purification and reducing costs for downstream enterprises.
Byproduct Utilization: The separated carbon black powder can be used as boiler fuel, filler for rubber products, or as a soil conditioner, achieving multiple benefits and improving overall economic efficiency.
Continuous Operation: From material feeding to steel wire recycling and dust purification, all operations are seamlessly completed via conveyors and automated equipment, eliminating the need for frequent manual intervention.
Zero Dust Emissions: The pulse bag dust collector captures over 99% of dust, completely eliminating the problem of "airborne dust" during traditional crushing, minimizing the impact on operator health and the surrounding environment.
