030301 Sinter plants - European Commission

Sinter plants Process description By sintering, the pelletisation of fine-grained, smeltable ores, iron ore in particular, to compact lumps by heating nearly to the melting or softening point is understood. Melting tendencies at the grain boundaries lead to a caking of the material. Before the sintering, the various substances are first mixed and, if desired, granulated. The iron ores are ...
