发明名称 Process for preparing spherical granulates from powdery solids and granulated material prepared using this process.
摘要 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. <IMAGE>
