Comminution and classification technologies of iron ore

Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.

Sinter Plant Operations: Design, Physical And Chemical …

In the context of an iron ore sinter plant or steel production, this process is used to agglomerate iron ore fines with flux fines (such as limestone, dolomite, and pyroxenite) and coke fines as a solid fuel. When heated to high temperatures (between 1200°C and 1300°C), these particles fuse to form a heterogeneous, lumpy mass.

PComP-coated roller screens for iron ore pellets look like …

At a steel company in Mexico, roller screens that separate green iron ore pellets were coated with PComP-W and installed alongside rollers protected with standard coatings. After six months, the PComP-coated screens looked as good as new, but the rolls protected with standard coatings showed a dimensional loss of 6 to 15 mm, and required ...
