in modeling and control of the grinding process in industrial ball mills. Basic kinetic and energy models of the grinding process are described and the most commonly used control strategies are analyzed and discussed. Keywords: ... mathematical models and control methods are .
pressure in the system of any ball mills. From the figure, the physically meaningful region is between 0 < T < 1/(2m kB), and T > Tth where the threshold temperature is always greater than 1/(2m kB) respectively. 7. CONCLUSION We have considered a model for communution processes in ball mills using hamiltonian approach.
The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior. The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .
A mathematical model is a description of a system using mathematical concepts and language.The process of developing a mathematical model is termed mathematical modeling.Mathematical models are used in the natural sciences (such as physics, biology, earth science, chemistry) and engineering disciplines (such as computer science, electrical engineering), as well as in the social sciences (such ...
ball mill units. SAGT and MILL models both are based on the population balance model of grinding process. CYCL model is based on Plitt's empirical model of classification process in hydrocyclone units. It was shown that P 80 can be reduced to about 40 Pm and 42 Pm for the
