Many of us take for granted the ease by which iron items might be obtained. We seldom take into consideration exactly where iron comes from, how it got there, or the numerous processes of refinement essential to convert iron ore into a usable item. Although it can be estimated that the earth's crust consists of as a great deal as 5 per cent iron, only in a few locations is it identified so very concentrated and in such volumes as to be produced economically.

The mining activity within the iron ore mines consists of extraction of your ore, breaking the rocks into modest stones and pebbles and into fine powder. Iron ore is purchased and sold in all these types. The smelter at Hospet-Sandur owned by the Jindals, processes the ore into rolled sheets of iron. Hence, the mining region has vast stretches of extraction sites, stone crushers, stockyards, dump yards, weighing and permit yards, lorry yards, and wagon loading points across the railway line, While most of the leases given by the mines department are around the hills spreading across 180kms of Khurda & Badbil district, the smaller private mines have extended into the agricultural lands almost as close as Khurda & Badbiltown itself. The shift to mining from agriculture was both a result of desperation as it has a quick profit motive.

The choice of crusher depends on the type and amount of material to be crushed. gyratory and jaw crushers represent the bulk of primary crushers used at mining operations today, despite the fact that some operations use roll impact crushers, low-speed roll sizers and feeder breakers. Cone crushers remain the most popular for fine crushing applications, while some mines use vertical impact crushers for tertiary and quaternary crushing.

The major equipment inside a primary crushing circuit usually includes only a crusher, feeder and conveyor. Secondary and tertiary crushing circuits have the same basic equipment items, along with screens and surge storage bins. In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements even though keeping capital and operational costs to a minimum. This paper addresses the critical design parameters as well as the consideration of ore characteristics, geographical location, climatic conditions, expected operational life, expansion potential, safety, environment, and operability and maintainability.
