PROCESS FOR FORMING DUST-FREE ADDITIVE GRANULES

摘要

The present invention relates to a process for forming substantially dust-free additive granules, comprising the steps of: a) extruding or otherwise processing an additive or blend of additives to provide an substrate; b) cooling the substrate; c) conveying the substrate onto a profiled surface; and d) fragmenting the substrate into granules by means of a first rotating roller bearing on the substrate on the profiled surface.
