Abstract

Inventia se refera la un procedeu pentru macinarea deseurilor de forme din ipsos, rezultate din industria portelanului si a faiantei sau a altor materiale similare, macinarea realizata la o finete avansata. Procedeul, conform inventiei, prevede ca materialul cu umiditate pâna la 10% sa fie supus într-o prima faza unei sfarâmari prin compresiune si forfecare în concasoare cu falci, dupa care într-o a doua faza de sfarâmare-maruntire, pe baza unui efect de soc în mori cu ciocane pâna la o finete de macinare de 0% reziduu de sita de 0,71 si 20% pe sita de 0,09.The invention relates to a process for grinding waste plaster molds resulting from the porcelain and tile industry or other similar materials, the milling performed at an advanced fineness. The process according to the invention provides that the material with humidity up to 10% is subjected in a first stage to a compression and shear breakage in jaw crushers, and then to a second crushing-crushing phase based on an effect by hammer mills to a fineness of 0% sieve residue of 0.71 and 20% per sieve of 0.09.
