Abstract： Based on the application of carbon black pneumatic conveying in rubber factory, the optimization of major parts such as the pipeline device, airflow-control unit, feeding device, and separation-filtration equipment etc. were conducted. The safety valve, pressure regulator, air filter and Laval nozzle were chosen and calculated. The conveying safety, conveying pipe materials for special carbon black, such as N772, N774 were specified. The results show that by optimizing main items of pneumatic conveying system, a low energy consumption can be gotten and the phenomenon of high pellet breaking, residual carbon black in pipe after conveying, break up of carbon black and leaking can be improved, which insure running reliability and smoothness of the carbon black conveying system.
