Swing mill used to pulverize ore sample. This is one of several identical mills that fit into a 'dishwasher size' machine that moves the mill in a way to cause the interior rings to swing about, crushing the rock sample. The machine 'processes' each sample for 1—2 minutes. Timing of mill operation is critical to successful mining. The mill is carefully cleaned with compressed air between samples.
