Experimental Research on Carbon Black Flowing in Pneumatic Conveying System
The article analyses the main factors such as the species and character of the carbon black, the conveying pressure and gas-flow rate which influence the flow character of carbon black during pneumatic conveying. And also studies the flow character of carbon black in dense phase pneumatic conveying system with experiment. It raises the view that the carbon black with narrow particle diameter distribution, especially with bigger size is favorable for saving energy and reducing fragmentation; the conveying pressure approach lowest point should be chosen during carbon black pneumatic conveying, and the quantity of elbow pipe should be used as less as possible; on condition that the conveying capacity is guaranteed, the lower air feeding volume is preferable; the higher the conveying pressure is, the lower the fragmentation of the carbon black will be. The article also supplies the reference for technology parameter choosing and carbon black conveying system design.
