WhatsApp: +86 18203695377High Pressure Grinding Rolls ("HPGR") are applied in all stages of iron ore size reduction, from coarse ore grinding down to pellet feed preparation. In closed circuit operation, fine grinds can be achieved using HPGR in combination with dry or wet classification or a partial product recycle without classification. For fine product cuts,
WhatsApp: +86 18203695377The Tecnored process is developed in Brazil. The process uses self reducing briquettes from iron ore and fine coal. These briquettes are cold bonded. Iron ore reduction in the self reducing briquettes is very fast. As a result Tecnored can limit the height of its reduction shaft and thus limits the mechanical load on the cold bonded briquettes.
WhatsApp: +86 18203695377The comminution of ores consumes a high portion of energy. Therefore, different pretreatment methods of ores prior to their comminution are considered to reduce this energy. However, the results of pretreatment methods and their technological development are scattered in literature. Hence, this paper aims at collating the different ore pretreatment methods with their applications and results ...
