Materials obtained from End-of-Life Tyres - Granulated rubber - Determination of textile fiber content by visual index (qualitative method)

Scope

The purpose of this Technical Report is to provide information about a procedure based on the determination of a visual index correlated with the content of textile fibers, free and bounded to the rubber, of granulates. This approach is currently used by Spanish grinders in order to control the efficiency of their processes and is effective for granulates with particle sizes whose bottom limit is higher than 0,5 mm and upper limit lower than 10 mm.
