A bulk solid blending simulator for longitudinal stockpiles has been developed using the Visual Basic development platform for Windows®. The program can be applied to optimizing blending in stockyards of mines, coal-fired power plants or cement industries. Input to the simulator consists of the average value, the standard deviation and the autocorrelation of the property for which blending is attempted. The program initially creates a time series of property values for the material delivered to the stockyard. Then, this input sequence is rearranged by simulating the operation of the stacking and reclaiming equipment. The output sequence of property values reflects the quality fluctuation of the material as it is delivered to the customer.
