Title:
改良されたドロス原料
Document Type and Number:
Japanese Patent JP7361803
Kind Code:
B2
Abstract:
The efficiency of roasting black dross can be improved by pre-processing the black dross before roasting. Black dross can be crushed and reconstituted into pellets having internal channels. The internal channels can be filled with additives designed to fully oxidize during a dross roasting process, enabling the internal channels to be open and gas to flow therethrough during a dross roasting process. The crushed black dross can be crushed to pieces below 10 mm and screened for larger pieces prior to pelletizing to ensure consistent pellets. Optionally, an eddy current separator can remove some metallic aluminum from the crushed black dross prior to pelletizing.
