Within tyre recycling the main objective has been to purify the rubber granulate. There is, however, also a substantial amount of steel wire in tyres, which previously has been overlooked in terms of a re-sellable material. Due to the growing demand for cleaning of the steel, Eldan has developed systems to meet the specific customer requirements for cleaning and upgrading of the steel fraction originating from tyre recycling. There are two systems offered – an inline solution and a “stand-alone” solution. The systems remove the textile and rubber residues from the steel, making it a high quality steel fraction.
The In-Line Systems are designed to be placed in-line with an existing Eldan tyre recycling plant, screening the outlet steel from the plant. The quality of the cleaned steel depend on size and purity of the input steel wire. As an example; if the input steel is up to 20mm in size containing 15-20% rubber and textile, the output fraction is approx. 94-95% clean steel wire (density 0,3) processing at 2,5-3 ton/production hour. Benefits with this system is low running costs (due to screening process), minimal operator control and naturally a high quality steel output.
The Stand Alone System include a Multi Purpose Rasper and Screening System. The output purity and capacity depend on the type of rasper and screen used. The system can be placed either in-line with the tyre recycling plant or it can be operated as a separate unit. As an example: including a medium size Multi Purpose Rasper (MPR160) and cleaning up to 50 mm steel wire (containing up to 30% rubber & textile) approx. 98-99% clean steel wire (density 0,7) can be obtained at a capacity of 2 ton/production hour. Benefits with this system is a high density steel output, high quality steel output and minimal operator control.
