Figure 1. Monarch Cement Company's Plant in Humboldt, Kansas. Figure 2. The ball mill where the first two grounding rings were installed at the Monarch Cement Company plant. The bearings of the mill's 5,000-HP motor failed regularly until damaging voltages were diverted by an AEGIS iPRO Bearing Protection Ring (inset) at each end of the motor.
