Abstract: The invention relates to a process for preparing spherical granules from pulverulent solids and the granules prepared by the process. The process is characterised, inter alia, in that the pulverulent solids, if required together with the binders, lubricants and plasticisers conventional for pressing solids are uniformly moistened by addition of an appropriate amount of liquid and mixing in a mixer, pressed in a ring matrix press to give cylindrical agglomerate rods and then rounded in a rounding unit having a fluted disc. The solids granulated by this process exhibit a very narrow grain size spectrum and are distinguished, depending on process conditions, by good flowability and good dispersibility.

Abstract: The invention relates to spherical carbon black granules which can be obtained from pulverulent carbon blacks. The carbon black granules are obtained by uniformly wetting the carbon blacks, together if desired with binders, lubricants and plasticisers which are customary for the pressing of carbon blacks, by addition of an appropriate quantity of fluid and mixing in a mixer, by pressing the wetted composition using an annular die press to give cylindrical strands of agglomerated material, which are then rounded in a rounding unit which has a fluted disc. The carbon blacks granulated by this method have a very narrow particle-size spectrum and are distinguished, depending on the particular procedure employed, by good flowability and good dispersibility.
