The mill can achieve a size-reduction ratio (the ratio of feed particle size to final product particle size) as high as 40-to-1 in one processing pass. 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,

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide converts iron oxides to elemental iron. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide.
