This pulverizing system is easily adaptable to multiple coal type and is simple to operate, thus it is suitable for pulverizing coal with low grindability, high abrasiveness and required degree of fineness.

  • 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.Ball and Race Mill ~ ME Mechanical,In ball and race mill the coal passes between the rotating elements again and again until it is pulverized to the desired degree of fineness. The coal is crushed between two moving surfaces namely balls and races. A worm and gear drove the upper stationary race, and the lower rotating race holds the balls between them.
