Method and apparatus for conveying carbon black which inhibits the build- up of carbon black fines on conveying surfaces

摘要

A method and apparatus for conveying carbon black pellets to avoid breaking up the pellets and inhibit caking on the conveying means which may be a screw type conveyor that is sufficiently heated to inhibit caking of the carbon black. The conveying means is centerless ground to maintain uniform distances of relatively moving parts and the contact surfaces are electroless plated to further inhibit caking of the carbon black on the conveying means.
