and the traditional dry grinding method was used as a reference. The effect of wet grinding on the activation of IOTs was evaluated through ion leaching from an alkaline solution and the reactivity index. Additionally, a detailed comparison between Dry-grinding Iron Ore Tail ings (DIOTs) and Wet-grinding Iron Ore Tailings (WIOTs) was made

May 25, 2017 Dry Grinding VS Wet Grinding. The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet

iron ores were 8.9, 6.5, 25, and 15.8%, respectively for wet and dry grinding. Variation in D/L indicates that abrasion is a prominent phenomenon in dry grinding and chipping is more prominent in wet grinding especially for material with bedded structures.

Sep 13, 2005 Sep 12, 2005 I'll bet I still have that iron dust in me. The VBM (mostly used for maching mating surfaces of manhole covers and flanges) was set off by itself so it didn't get the rest of the shop rooms filthy. Always dry of course: I don't remember any discussion of wet machining of cast. This was the old way. The grinding room was worse but it all was a mess
