in the region of connection will be a shaped section corresponding to the non shaped section 10 the sections 9 that follow one after the other separated by non shaped sections 10 are positioned with respect to each other in such a way that not only the shaping ridges 11 but also the recesses 12 are completely in alignment in this manner a straight line flow of material as indicated by arrow 17 is enabled in which the material to be pulverized can be directed away from the grinding container region relatively quickly this type of shaping arrangement for element 1 is suitable above all for producing coarse grained fine material in fig4 another embodiment of an element 1 u2032 according to the invention is shown the construction of element 1 u2032 corresponds for the most part to that of element 1 the only difference is the orientation of the ripple ridges 11 u2032 of the shaping arrangement and the recesses 12 u2032 disposed therebetween in order to retard the material flow and thus to increase the holding time within the grinding container of the material to be pulverized the impedance and deflection of the material flow is carried out abundantly with the assistance of the shaping arrangement shown in fig4 for this purpose the shaping ridges 11 u2032 and recesses 12 u2032 of a shaped section 9 u2032 are shifted with respect to the shaping.
