Artificial Neural Network Modeling of Ball Mill Grinding Process
Milling is a vital unit operation in various material processing operations and consumes around 2% of the energy produced in the world [1,2]. It dictates the cost economics of mineral, cement, power, pharmaceutical and ceramic industries. Grinding is an important unit operation for chrome ore pelletisation process. Chromite ore along with 5% coke is milled in the wet ball mill and filtered ore ...
متن کاملHybrid Intelligent Modeling Approach for the Ball Mill Grinding Process
Modeling for the ball mill grinding process is still an imperative but difficult problem for the optimal control of mineral processing industry. Due to the integrated complexities of grinding process (strong nonlinearity, unknown mechanisms, multivariable, time varying parameters, etc.), a hybrid intelligent dynamic model is presented in this paper, which includes a phenomenological ball mill g...
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 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 کاملMODELING AND OPTIMIZING THE CORROSIVE WEAR OF STEEL BALLS IN BALL GRINDING MILL
This paper was aimed to address the modeling and optimization of factors affecting the corrosive wear of low alloy and high carbon chromium steel balls. Response surface methodology, central composite design (CCD) was employed to assess the main and interactive effects of the parameters and also to model and minimize the corrosive wear of the steels. The second-order polynomial regression model...
