Although placing product in a stockpile endangers its quality, stockpiling is a vital link in the aggregate production process. It is a storage method that ensures material availability. The rate of production often differs from the rate at which the product is required for a given application, and stockpiles help to absorb the difference.

Calculating Stockpile Capacity Once the minimum storage capacities which will assure maximum mill output are known, the appropriate stockpile configuration must be determined. Stockpiles fall into two general categories conical and elongated. Conical Stockpiles The conical stockpile is the simplest and easiest to analyze. The total stockpile capacity is given by 3.14 Tan AR D3000

In practice, many stockpiles are stored and loaded by forcing machine with special arrangement space in a real storage yard. In a general manner, coal is stocked via a combined stacker reclaimer which runs parallel to the piles along the centre rail track. Wheel loaders and mobile hoppers are used to load coal into trucks or trains.
