Verfahren zur Verarbeitung von Abfall zu körnigen Produkten

摘要

Method to transform into granular products waste residues from the mechanical processing of ceramic products, the granular products being used as abrasive products in textile washing processes, the method providing to subject the waste residues to a step of mixing with additive components, to a step of molding and to a step of heat treatment, wherein the percentage in weight of the waste residues is between 80 and 95% and the remaining 5 DIVIDED 20% consists of the said additive components, the molding step providing to obtain closed-pore granules substantially spherical in shape with a diameter of between 2 and 50 mm, there also being included a step to finish and cover the surface of the spherically shaped granules emerging from the molding step. Granular product obtained by transforming waste residues from the mechanical processing of ceramic products.
