Abstract: The aim of this paper is to optimize the production of the iron ore pellets by rectifying and providing alternate solutions to the problems that are occurred in the sinter plant of RINL- VSP(vizag). The intial problem that occurred is in hammer crushers where the breaker plates are being damaged due to high impact load.
Advances in screening technology in the mining sector
A total of 6 parallel lines process 9500 t/h of ore. Screening equipment is installed after the primary crusher, after the scrubber and after the tertiary comminution stage to separate the iron ore into a dry coarse fraction (8 – 40 mm) and a wet fine fraction (> 1 – < 8 mm). The fraction < 1 mm passes through another washing stage.
Development of an automated single particle impact tester for iron ore …
Thus all particles, which pass a 6.3 mm mesh are declared as return fines. As iron ore sintering is a highly energy consuming process, these return fines cause high costs and emissions. For sinter process optimization and engineering of following conveying plants sinter breakage behavior is a very important aspect.
