    01.02.2015· For the first 12 h of ball-milling, SSA of zinc oxide stabilized with 2 and 3 wt.% of PCA remains almost steady at 7377 and 7156 m 2 /kg respectively. After 12 h of ball-milling, there has been a marginal decline in SSA of zinc oxide irrespective of the concentration of PCA. An interesting observation is that the SSA of zinc oxide stabilized with 2, 3 and 4 wt.% PCA coincides after 24 h of ball-milling.

  • Ball mill Wikipedia

    The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials, wet or dry. There are two kinds of ball mills according to their ways of

    For this reason, zinc production by this means is now obsolete. Early attempts to devise a blast-furnace process for zinc production failed because of the difficulty of condensing zinc vapour from a gas containing substantial quantities of carbon dioxide. This difficulty was finally overcome in the mid-20th century by the development of the lead-splash condenser, a means of shock-cooling furnace gases

  • A Mechanochemical Zinc-Mediated Barbier-Type

    A ball-milling-enabled zinc-mediated Barbier-type allylation reaction is reported. Notably, running the reaction in this manner renders it effective irrespective of the initial morphology of the zinc metal. The process is operationally simple, does not require inert atmospheres or dry solvents, and is reported over a range of aldehyde and ketone substrates; a gram-scale process is demonstrated.
