Industrial IoT and Closed-Loop Process Control
#1IIoT sensor costs have fallen 60–80% over the past decade, making full instrumentation of grinding, crushing, and polishing lines economically viable even for mid-size operators. Vendors including Metso Outotec (ACT autonomous controller), FLSmidth (ECS/ProcessExpert), and ABB (Ability Expert Optimizer) are actively deploying closed-loop AI control systems in mineral processing, ceramics, and metals grinding that adjust all major process parameters — feed rate, mill speed, classifier cut point, water addition — autonomously at intervals of seconds to minutes, with demonstrated throughput improvements of 3–8% and energy reductions of 5–12% versus human-controlled baselines. These business cases are compelling enough that adoption is driven by ROI independent of labor cost reduction.
