view moreIn summary, while ball mills are effective tools for making black powder, the selection of appropriate ball mill media is crucial for the quality and efficiency of the production process. Whether using ceramic balls, flint pebbles, or stainless steel balls, choosing the right media is vital for producing high-quality black powder.
view moreThe ball mill was operating at 45 t/h during the audit period. Conventionally, a ball mill is preferred for fine grinding, whereas a rod mill is for coarser grinding (Napier-Munn et al., 1996). The top particle size in the feed to the ball mill was 25 mm, which is very high for this type of mill.
view moreThe ball mill treatment reduced chromite grains greater than 15.77 µm down to sizes less than 11.15 µm in diameter, and thus released chromite-bound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 15.77 to 37.5 µm to below 15.77 µm.
