摘要

A method and apparatus for receiving of carbon black pellets for weighing prior to injection into an internal mixer which inhibits the accumulation of carbon black fines on the internal surfaces including a receiving and weighing hopper having walls formed of smooth flexible material which flexes upon loading and unloading from an equilibrium position to expel carbon black fines that tend to adhere on the wall surfaces of the hopper.
