Achieving particle size reduction with a multirow cage mill

The cage mill's high size-reduction ratio results from its crushing mechanism: impact rather than compression. While a compression mill, such as a jaw or roll crusher, slowly applies the crushing force, an impact mill, like the cage mill or vertical shaft impactor, does so suddenly and quickly. Since energy plus material equals size reduction,

BOF and EAF Steels: What are the Differences?

Mar 07, 2016The answer lies in capital costs. For a BOF firm, the average cost per ton of capacity is $1,100, while the cost for an EAF minimill per ton of capacity is only $300. The barrier for entry is thus lower for EAF firms, which can in part explain the rise of such "minimills" over the last half of the 20th century and into the 21st (WikiInvest).
