Centrifugal Impact Mill from Munson Machinery grinds friable materials, reduces flakes and de-agglomerates materials at rates to 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 centre 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 864 mm diameter and mild steel construction, the unit is also offered in diameters of 203, 457 and 610 mm with 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 utilised for bulk pharmaceutical ingredients, nutraceuticals, flour, fish food, grains, spices, salt and sugars, as well as contamination-sensitive bulk chemicals.
