Abstract: The fragmentation mechanism of the carbon black was anal ysed. According to the experiments, the influence factors of the different type of carbon black and its physical character for the carbon black frag mentation in the pneumatic conveying system were introduced. It was pointed out that the pipe length and its layout and the conveying parame ters such as conveying pressure and velocity of the pneumatic conveying system were the main influencing factors about the fragmentation rate. The bases for solving the problems better when using the pneumatic con veying system and optimizing the design of the pneumatic conveying sys tem were suggested.
