Nonlinear Modelling and Simulation of Industrial Wet Grinding Process
The multiple linear models based piece-wise linearization approach is used to obtain control-oriented non-linear model of the non-linear multivariable wet grinding process of an industrial lead-zinc ore beneficiation plant. The overall process outputs are computed as a weighted sum of outputs from multiple models identified at several operating zones. The output weights of linear models are com...
متن کاملMicro Cutting Simulation of Abrasive Grains in the Grinding Process
In the current work we present approach to study the mechanism of the cutting of abrasive grains in the grinding wheel using finite element analysis (FEA). The simulation process is done by separating two abrasive grains from the grinding wheels and the microprocess of material removal in the case of surface grinding is simulated. Modelling was done on the workpiece steel S-7 and material grain...
متن کاملModeling of the Process of Coal Grinding
T. Wyleciał, H. Radomiak, D. Urbaniak, Częstochowa University of Technology, Czestochowa, Poland The use of coal in the steel industry, similarly as in the whole national ec onomy, is often preceded by its pre-treatment. Coal is mined in the form of big solids, but, being in such a form, it can’t be combusted, sintered, or gasifi ed. Therefore, it needs t o be appropriately grinding. In the pap...
متن کاملSimulation of grinding mill-classifier systems
Abstract: Discrete mathematical model was developed for analysis and design of the continuous grinding mill-classifier systems. In the model, the mixing of the material to be ground by the axial dispersion model, the breakage kinetics by the first order breakage law, and the classifier by a usual classification function are described. This model is the basic of computer simulation. Computer pro...
متن کاملSimulation of Cement Grinding Process for Optimal Control of SO3 Content
Cement is produced by co-grinding clinker, gypsum and other components defined in the Cement Standards like limestone, pozzolans, fly ash and slag. The grinding is usually performed in horizontal ball mills. Gypsum is typically the basic source of sulphates (SO3) in the cement. The effect of gypsum on the cement quality is critical and twofold. It affects two of the main properties of this prod...
