1. Introduction. Due to the decreasing reserves of high-grade iron ore and secondary resources used for steelmaking, it has become an important research and development area to improve the grade of iron ore through crushing (Gul et al., 2014).The quality of iron ore crushing directly affects the performance of pellets and sinter, so as …
In iron ore processing plants, crushers are used to perform comminution up to a defined range for the next stage of the process, grinding. It is very common to use tapered crushers, and the crushing occurs within a cavity called the chamber, whose capacity is defined by the distance between the concave and the mantle. ...
Gyratory crushers. Run of mine material is transferred into a gyratory crusher's upper-level hopper. The walls of the gyratory crusher's hopper are lined with "V-shaped" pieces, the mantle and the concave, like a jaw crusher but shaped like a cone. The ore is discharged through the smaller bottom output hole of the cone.
