Crushing Circuit - an overview | ScienceDirect Topics
Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.
EFFICIENT IRON SINTERING PROCESS CONTROL - Prolab Systems
Sintering is one of the iron ore post-processing steps to prepare iron ore fines for a blast furnace Feed for a sinter plant consists of iron fines, coke, and flux (eg limestone). The feed is placed on a sintering bed, where thermal agglomeration (1300-1480 °C) takes place to produce clustered lumps, aka iron sinter (5-20 mm in size).
