Modeling and simulation of ball mill coal-pulverizing system

The paper presents a mathematical model and its Matlab/Simulink realization for ball mill coal-pulverizing system (BMCPS). Based on the analysis of mass and energy balance, the physical models for all control-related sub-processes of BMCPS are developed respectively. Then the integrated dynamic mathematic model is constructed with Matlab/Simulink. …

Exploring ball size distribution in coal grinding mills

The steady state ball size distribution in the mill depends on the top-up policy. The effect of the ball size distribution on the milling rate of coal has been measured as a function of ball size distribution. The change in ball size distribution as affected by wear and ball top-up policy has been modelled.
