Micro Sizer® RMC

The Micro-Sizer RMC® is not a reinterpretation of air-swept mill classification — it is a direct extension of the original Micro-Sizer® Air Classifier platform and the same engineering principles that originated high-efficiency classification in air-swept mills. Long before “high-efficiency” became a generic industry term, Micro-Sizer® technology established how controlled classification zones, stable particle disengagement, and selective transport determine product cut and efficiency inside a mill environment. The Micro-Sizer RMC® applies this original classification logic directly within the air-swept mill, integrating grinding and classification as a single, coordinated process rather than treating them as independent functions.

Where copy-based systems attempt to improve performance through incremental geometry changes or increased airflow, the Micro-Sizer RMC® is engineered from first principles to control particle behavior at the point of classification. This originator-driven design enables immediate, stable product selectivity, typical production increases of 20–50%, horsepower reductions of up to 50% per ton, and the ability to produce 99% minus 30 µm, 20 µm, and even 10 µm material directly from the mill. The Micro-Sizer RMC® is not a retrofit inspired by later-market interpretations of efficiency — it is the continuation of the technology that defined it.

The Micro-Sizer RMC® has been applied across a wide range of air-swept mill applications, including roller mills processing clays, carbonates, activated carbon, and other fine industrial minerals, as well as bowl mills grinding petroleum coke and coal. These installations span materials with widely differing grindability, density, abrasiveness, and flow behavior, yet all benefit from the same Micro-Sizer® classification principles applied within the mill. Performance gains achieved across these diverse materials confirm that the Micro-Sizer RMC® is not tuned to a single product or operating window, but is a fundamentally robust classification platform validated in real production environments.
