Experimental investigations on the wet batch comminution of an alumina hydrate in a stirred bead mill are presented. The influence of some operating parameters (mass solids concentration, initial size of particles, stirrer speed and beads size) on both the specific energy and the size distribution of the ground product is discussed.

All catalysts were tested with respect to the hydrogenation of CO 2 to methanol in microactivity fixedbed reactor at 250 o C, MPa, and H 2 /CO 2 ratio of 3. The results demonstrate that the catalytic structure, activity, and methanol selectivity was strongly affected by the ratio between Cu: Zn, Where higher catalytic activity of 14 % and ...

Oct 20, 2015· The ceramic industry is one that stands out in the use of industrial tailings, replacing pure raw materials by some of these materials. Refractory wastes are ground and used in certain proportions in refractory production. This study is aimed at determining the grindability of recycling of refractory wastes and their kinetic behavior. The breakage behaviors were determined experimentally by ...

Aug 12, 2020· This manuscript aimed to examine the impact of operating parameters on the wet grinding of talc in a verticaltype stirred media mill. Within the scope of the research, the effects of operating parameters including media filling ratio, solid mass fraction, grinding media size, and grinding time were studied. The findings were assessed based on the product particle size (d50, d10), surface .
