  • Calculating Stockpile Capacity

    Conical StockpilesElongated StockpilesCalculate Stockpile Live StorageThe conical stockpile is the simplest and easiest to analyze. The total stockpile capacity is given by: 3.14 (Tan A)R³ D/3000 = capacity in metric tons(1) where: R = stockpile radius in meters A = angle of repose for material to be stockpiled D = density of material in kg/m³ Note that the capacity of the conical stockpile varies with the cube of the radius of the pile. This means that the capacity of the conical pile grows very rapidly as 在911metallurgist上查看更多信息

  • effective angle of repose for coal conveyors

    This drawdown angle varies from material to material but is usually about ten degrees steeper than the angle of repose for the material. In other words, if the angle of repose is 38 degrees, the drawdown angle is usually about 48 degrees. Obviously, the drawdown angle will vary depending upon the size range of the material and its wetness.
