Abstract: 

Computer simulation of various unit operations is a well-established tool in mineral processing. The principal application areas include the design, analysis/optimization and control of processing systems. Considering the extensive use of classifying devices in closed grinding circuits, mathematical modelling and computer simulation of hydrocyclone as the most standard classifier is of great importance. In this paper we concentrate on Microsoft Excel as the basic environment for simulating hydrocyclone. The Plitt’s empirical model (1976) for hydrocyclone is used for simulation. The dependent variables in this model are: cyclone throughput, cut size, volumetric flow split and sharpness of classification. The design or independent variables are: diameters of the cyclone, vortex finder, spigot and inlet and free vortex height. The Plitt model in its current form as revised by Flintoff et al. (1987) does not depend on feed size characteristics in any of the equations, but they provide a number of factors for calibration purposes. Microsoft Excel has a user friendly interface and a large number of built-in functions, which significantly facilitate both development and simulation efforts. In addition by implementing mathematical models of hydrocyclone using visual basic macros, a powerful simulator and easy to use environment has been created. The input data and output results of each simulation run are easily shown by tables and figures which greatly assist the user in circuit analysis tasks.
