<p>The method involves processing rubber granules (7, 8) or powder by floatation in floatation cells (4) that are connected in series, where the rubber granules or powder contain natural rubber, butyl rubber and/or halobutyl rubber. The granules or powder are obtained by milling all scrap tires of commercial vehicles, where the granules have grain size of 50 to 3 mesh. The granules are suspended in water for the floatation, and air is utilized as gas for the floatation. The processed granules are dried. The processed and dried granules are regenerated.</p> |
