Aggregate processing plant

All over the world not only in one or two, three countries, we can see construction work related various items like buildings, bridge, culvert, etc for those aggregate processing plants are required. Then what is aggregate processing plant? Yes, aggregate processing consists of crushing, grading, washing and stock piling of aggregate and sand. Large processing plants comprises of primary crusher, scalping (primary) screen, washing system, secondary crusher, grading screens, belt conveyors, sand mills, sand screens, storage piles and reclaiming system.

Quarry  materials as recovered is delivered to the scalping screen where acceptable sizes of aggregate are separated, fines are removed, and oversize is passed on to the primary crusher. The crushed aggregate received from primary crusher is conveyed to the screens for grading the aggregates as required for concrete mix. Jets of water are directed over the screens, to produce clean aggregate which then moves to the grading screen. Water requirement is about 60 to 90 lits per min TPH capacity of the plant. Aggregates from stock piles is reclaimed through belt conveyors running under the stock piles in reclamation tunnel. It may also be reclaimed through skip buckets operated by hoist cable or by a grab.

Sand producing plants (some times known as sand crushers), consists of sand mills or crushers, dry screens, washers, conveyors and storage bins. Arrangements for removal of waste products from aggregate producing plants are also made.
