Centrifugal impact mill maximises productivity and process control
Centrifugal Impact Mill provides coarse to fine grinding of friable materials into controlled particle sizes, as well as lump breaking and conditioning of fibrous materials.
The Centrifugal Impact Mill from Munson Machinery offers manufacturers a powerful solution for grinding, de-agglomerating, and reducing friable materials — in both wet and dry forms — with speed, precision, and reliability.
Capable of processing up to 142 litres per minute, the mill delivers narrow and consistent particle size distributions without the need for screens, reducing downtime and maintenance while improving product uniformity.
Its high-speed inner disc generates centrifugal force to propel material through five intermeshing rows of rotating and stationary pins, ensuring uniform results and efficient size reduction. Manufacturers benefit from precise control over particle size, supporting both coarse and fine grinding operations — from initial de-agglomeration to final product fineness of up to 325 mesh.
Because material retention is minimal and a constant flow of air is drawn through the chamber, the system maintains lower operating temperatures than conventional mills. This minimises thermal degradation, helping manufacturers preserve product quality, especially for heat-sensitive materials.
The infinitely variable rotor speed (from several hundred rpm to 5400 rpm) allows manufacturers to easily fine-tune the process for diverse materials and production requirements, maximising flexibility and reducing the need for multiple machines.
Engineered for fast, hygienic maintenance, the unit features smooth, crevice-free internal surfaces and hinged, vertically oriented outer discs that allow full access for rapid cleaning and inspection.
The model CIM-34-MS (864 mm diameter, mild steel) is one of several available configurations, with additional sizes ranging from 203 to 610 mm diameters and motor options from 4 to 93 kW to suit varying throughput requirements.
Industrial users rely on the Centrifugal Impact Mill for efficient processing of ceramic filter media, chalks, coal, friable resins, dry clays, gypsum, pigments, and powdered metals.
For contamination-sensitive or food-grade operations, sanitary stainless-steel models deliver the same performance benefits in applications including pharmaceutical ingredients, nutraceuticals, flours, fish foods, grains, spices, salts, sugars, and fine chemicals.
With its combination of high throughput, precise control, low maintenance, and flexible configuration, Munson’s Centrifugal Impact Mill empowers manufacturers to increase efficiency, improve product consistency, and reduce operating costs across a wide range of materials and industries.
