Pulveriser in Thermal Power Plant Bowl Mill Ball Mill

The Ball mill pulveriser is basically horizontal cylindrical tube rotating at low speed on its axis, whose length is slightly more to its diameter. The inside of the Cylinder shell is fitted with heavy cast liners and is filled with cast or forged balls for grinding, to approximately 1/3 of the diameter. Raw coal to be ground is fed from the

Modeling and simulation of ball mill coal-pulverizing

2011-6-23  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. Validation
