Course Contents : In recent years, especially investigation of grinding has been developed a new approach which the basis of theoretical basis, such as heat transfer water treatment systems . In particular, the chemical reactor system design is similar in many ways and used to design a reactor is based on the ideas and terminology. Grinding are two basic concepts used in this model is defined as the kinetic approach. First, the cumulative loss rate-based model, and the latter model based on energy consumption. In the cumulative loss rate-based model, depending on sieve size the brittle materials based on how to speed broken and how to distribution. In the kinetic model, before the mathematical model wil be developed the defining breakage function and distiribution of breakage, the parameters defining breakage and breakage distribution of materials will be determined. In the breaking process defined in mathematical terms, is possible to calculate the amount of size distribution at the end of crushing and grinding process . The simulation methods and programs are used this calculation. In addition, the simulation program added the parameters of classification are done control and design of various grinding circuits.
Languages of Instruction : Turkish
Course Goals : Size reduction process, which is expressed as mathematical models to understand
Modeling and calculation of parameters of size reduction processes
Circuit of the crushers and grindind the measurement of performance
Course Aims : The grinding proces is consumed more energy in mineral processing. In this area Even a very small improvement, energy consumption will too much reduced. In this course the basic philosophy of reducing the size, the properties of breakage are detected to based modeling in comminution of materials, comminution (crushing-grinding) circuit will optimized how to learn .
