Title:
PRODUCTION PROCESS OF FINE AGGREGATE FROM FUSED SLAG OF WASTE MATERIAL
Document Type and Number:
Japanese Patent JP2002362950
Kind Code:
A
Abstract:
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.
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.
