UTICA, NY — Centrifugal Impact Mill from Munson Machinery grinds friable materials, reduces flakes and de-agglomerates materials at rates to 5 cu ft (142 L) per minute, yielding narrow particle size ranges without the use of screens.
High speed rotation of the inner disc creates centrifugal force that accelerates bulk material entering the central inlet of the opposing stationary disc. As material travels from the center to the periphery of the discs at high speed, it crosses five intermeshing rows of rotating and stationary pins, yielding desired tight particle size distribution.
Materials remain cooler than in other types of mills since retention is minimal and air is constantly drawn through the mill chamber.
Setting the infinitely-variable rotor speed from several hundred rpm to 5400 rpm provides the flexibility for coarse grinding and de-agglomerating, or fine grinding to 325 mesh.
Also known as a Pin Mill, the unit features smooth interior surfaces with no crevices, and hinged, vertically-oriented outer discs, permitting unobstructed access to the interior for rapid cleaning.
Designated CIM-34-MS for Centrifugal Impact Mill in 34 in. (864 mm) diameter and mild steel construction, the unit is also offered in diameters of 8, 18 and 24 in. (203, 457 and 610 mm) with 5 to 125 hp (4 to 93 kw).
Typical industrial applications include grinding of ceramic filter media, chalks, coal, friable resins, dry clay, gypsum, pigments, and powdered metals.
Sanitary stainless steel models are utilized for bulk pharmaceutical ingredients, nutraceuticals, flour, fish food, grains, spices, salt and sugars, as well as contamination-sensitive bulk chemicals.
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.
