ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill's internals is less of an issue.

November's Puzzler. We operate an acid regeneration plant (ARP) for a steel mill. In the process, FeCl 2 solution is oxidized to Fe 2 O 3 and HCl in a spray roaster; the HCl is recycled to the mill and the oxide is agglomerated and pelletized for feeding back to the mill (Figure 4). Currently, operators do laboratory tests to monitor the quality of HCl (target: 18.5%).
