1. Iron ore crushing process: In the iron ore crushing process, the feeder, first crushing, secondary crushing, screening, fine crushing and dry selection are generally used. For the sake of economy, generally the finer the ore particle size entering the dry separator, the higher the proportion of iron-bearing ore that is dry selected.
This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground. Once the ore has been crushed, it is diverted to a stockpile. The aim of this step is to ensure a …
