摘要

Process for the transformation of resu00ecduo mines of crayons in compositions of colorants for use in polu00ecmeros thermoplastics.The invention relates to a process of transformation of waste of Mines of color pencil, composed of carbon, calcium, wax and colorant.In a composition of colorants for use in thermoplastic polymers virgins and / or recycled, with the goal of giving colour to these polymers.Through a physical processing of comminution and classification granulamu00e9trica in a system of it.
