摘要: An annular gap-type mill for continuously pulverizing in particular hard mineral substances comprises a grinding container (15) which accommodates an axially symmetrical inner body (13) whose outer surface defines with the inner surface of the grinding container (15) a grindimg gap (23). It is essential that the upper and lower region of the inner body (13) are tapered in opposite directions and adjoined to a common equatorial zone (24) of maxi diameter and that the outer surface of at least one of the regions is curved convexly. The grinding container (15) and/or the inner body (13) may be driven rotatingly. The annular gap-type mill is suited for wet and dry grinding and its quantitative and qualitative output is high.

摘要: An improved process for making acrylamide from a composition of acrylonitrile and water utilizing an improved Raney copper catalyst. The catalyst is prepared by contacting particulate copper/aluminum alloy particles with an aqueous solution containing aliphatic hydrocarbon compound having at least two carbon atoms per molecule and further having at least two oxygen containing groups per molecule.
