Cleaning Steel Wire From Waste Tyres Is A Crucial Step In Tyre Recycling, Enabling The Recovery And Reuse Of This Valuable Material. Several Methods And Technologies Are Employed, Generally Involving A Combination Of Mechanical Separation And, In Some Cases, Chemical Treatment. 

1. Mechanical Separation

Shredding: Waste Tyres Are First Shredded Into Smaller Pieces, Which Helps To Separate The Steel Wire From The Rubber And Fabric Components.

Magnetic Separation: Strong Magnets, Such As Over-Band Magnets Or Magnetic Rollers, Are Then Used To Extract The Steel Wire From The Shredded Material.  That Their Steel Cleaning Plant Uses Secondary Shredders And Magnets To Produce 98% Clean Steel Wire.

Liberators/Wire Cleaners: Specialized Machines Like Liberators Or Wire Cleaners Are Employed To Further Separate Residual Rubber And Textile Fibers From The Steel Wire Recycling Offers Different Systems, Including Those With Liberators, That Can Achieve High Purity Levels Of Up To 99% Clean Steel Wire.

Vibration And Screening: Vibration Tables And Screening Systems Can Also Assist In Separating The Steel Wire From Lighter Materials. 

2. Chemical Treatments (Sometimes Combined With Mechanical Methods)

Soaking In Organic Acids: A Method Involving Soaking Rubberized Steel Wire In A Pure Liquid Organic Carboxylic Acid, Followed By Cleaning With Solutions Like Ethanol Or Acetone, Can Non-Destructively Separate Steel Wire From Rubber.

Devulcanization: Research Indicates That Devulcanization, Either Partial Or Complete, Can "Dissolve" Rubber From Steel Wire. Partial Devulcanization, Combined With Magnetic Separation And Solvent Swelling, Can Effectively Clean Steel With Lower Environmental Impact And Cost Compared To Complete Devulcanization Alone. 

3. Burn-Off Ovens

Burn-Off Ovens Utilize High Temperatures To Convert Rubber Coatings And Contaminants Into Ash And Fumes, Leaving Clean Metal Parts Suitable For Recycling. This Method Is Considered Safer And More Efficient Than Using Chemical Stripping Agents Or Manual Removal, According To Armature Coil Equipment. 

Importance Of Cleaning

Cleaning Steel Wire From Waste Tyres Is Essential For Several Reasons:

Resource Recovery: It Allows For The Recovery Of Valuable Steel, Reducing The Need For Virgin Resources And Promoting A Circular Economy.

Environmental Protection: Proper Cleaning Prevents The Accumulation Of Tyre Waste In Landfills And Reduces Pollution Associated With Burning Contaminated Materials.

Economic Value: Clean Steel Wire Can Be Sold To Metal Recyclers And Reused In Various Industries, Generating Revenue And Creating New Markets For Recycled Products. According To Fornnax Technology, The Cleaned Steel Wire Finds Application In Large Steel Industries. 

Considerations For Choosing A Cleaning Method

The Most Suitable Cleaning Method For Waste Tyre Steel Depends On Several Factors, Including:

Desired Purity Level: The Intended Application For The Recycled Steel Will Dictate The Required Level Of Cleanliness.

Scale Of Operation: Large-Scale Recycling Plants May Benefit From Automated, Integrated Systems, While Smaller Operations Might Opt For Simpler Equipment Or Combined Approaches.

Cost-Effectiveness And Environmental Impact: Evaluating The Energy Consumption, Chemical Usage, And Waste By-Products Associated With Different Methods Is Crucial For Sustainable And Economically Viable Operations.
