Abstract
A carbon black pelleter having a pinned shaft rotatably arranged in a cylindrical housing is provided with one or more rows of pins (shell pins) attached to the housing in the lower half of the housing. The shaft pins during one revolution of the shaft are sandwiched between the shell pins, but not more than 1/6 of the entire sandwiching during one revolution of the shaft occurs at the same moment.
