PRODUCTION PROCESS OF FINE AGGREGATE FROM FUSED SLAG OF WASTE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a production process of fine aggregate from fused slag of waste materials slag that causes no cut in a worker's hand and has good quality can be produced at a low cost. SOLUTION: This production process comprises a stage for subjecting waste material incineration residues to fusion treatment to obtain fused slag, cooling and solidifying the fused slag to obtain waste material incineration ash fused glassy slag, and a stage for crushing the resulting waste material incineration ash fused glassy slag, wherein the waste material incineration ash fused glassy slag is crushed by using an impeller breaker.
