Abstract
The invention relates to a process for covering rubber particles with a continuous functional layer of polymeric nature, characterized by the use of a rotating drum with variable speed drive allowing for a progressive reduction of the speed and a pre-blend of a setting and filmifiable reactive fluid comprising a liquid resin selected from alkyd resins, polyvinyl chloride resin, urethane alkyd resins, polyurethane-urea resins and reactive polyester resins. The invention also relates to covered granulates obtained by this process.
