Efficient grinding and drying mill
Transform your production line with a versatile mill that simultaneously grinds, dries, and classifies, delivering ultra-fine powders with precise particle size control.
Grinds, Dries, and Classifies Materials
The Atritor Cell Mill from Scott Equipment Company offers a versatile solution for industries needing efficient ultra-fine powder production. This equipment simultaneously grinds, dries, and classifies a variety of materials, utilizing multiple rotors on a vertical shaft to achieve mean particle sizes below 20 microns. Its modular construction permits customized design to fit specific operational requirements, and an integral dynamic classifier ensures precise control over top particle size. The Cell Mill operates as an air-swept unit, enabling it to serve both as a flash dryer and a mill capable of direct slurry feeding. Manufacturing applications range from minerals like bentonite and kaolin to chemicals, dyes, pigments, and foodstuffs, with capacities spanning from 100 to 33,000 lb/hr and an evaporation rate of up to 6600 lb/hr. With components available in materials ranging from carbon steel to tungsten carbide, it is suited for diverse processing environments, supporting continuous and high-speed operations. The inclusion of a frequency inverter aids in energy efficiency by controlling mill speed and limiting starting current, while the choice of hardened, stainless, or tungsten carbide-tipped rotor blades offers enhanced durability and reduced maintenance needs.
