Simulating Coal Preparation Distribution Curves

Using a microcomputer a set of computer programs has been systematically developed to simulate distribution curves, calculate the performance characteristics of coal cleaning devices, display the distribution curve shapes on graphic screen or plotter and perform a reliability analysis of the simulated partition curves. Distribution curves for 81 sets of coal cleaning data covering six coal washing methods were studied using six different mathematical models. The importance of selecting a distribution curve model based on the shape characteristics of the curve as well as the normal statistical tests is illustrated
