S. A. ANDERSON, IKA Works, Inc., 2635 N. Chase Pkwy. S.E., Wilmington, NC 28405-7419 The Cone Mill is a new type of mill that provides superior wet milling performance compared to traditional mills, such as Colloid Mills. What makes the Cone Mill unique, is the hybrid design of the mixing tool, which combines the “grinding” action of a stone mill, with the fluid dispersing capabilities of a colloid mill. The conical shaped rotor and stator utilize spiral shaped teeth for pre-milling, and then a coarse surface coating for fine milling. The Cone Mill was developed by IKA and commercialized in January of 2002. Materials that are extremely hard, and difficult to mill can cause a bottleneck in production, and result in high maintenance costs associated with the heavy equipment required to reduce the particle size. The Cone Mill has been proven to eliminate the need for multiple passes when processing hard materials, such as some pigments and crystals. Soaking and heating of seeds before milling can also be eliminated, greatly reducing manufacturing times and costs. The Cone Mill may also eliminate the need for pre-milling of the solid materials, which can significantly reduce materials costs. The key feature of the Cone Mill is the unique design of the rotor and stator, which provide the extremely fine milling action. The rotor has an initial stage of spiral shaped teeth, and then two stages of increasingly finer coatings for abrasion. The stator also has the abrasive coatings in increasing fineness. The rotor and stator are conical in shape, which allows the gap between them to be adjustable. The gap determines the amount of milling action, and is adjusted according to the requirements of the application. The Cone Mill has been successfully used on applications in the Food, Pharmaceutical and Chemical industries. Applications include mustard seeds for the production of fine mustards, carbon black, quartz and pharmaceutical agents, color pigments, ion exchange resins for water treatment, and many others.
