The sanitary wet-mixing colloid mills process all particles through a single mixing head that processes all particles through a rotor and stator; exposing them to the same shear action which assures complete consistency and repeatability. Ideally-suited for manufacturing creams, lotions, and ointments, these mills include a variable frequency drive for precise speed control and adjustability, and can be integrated into any process system. Available with rotor and stator combinations to achieve particle size reduction from pulpy slurries to customer-specific homogeneous viscosities, the units are capable of 10 to 10,000 GPH throughput. Fully scalable and offered for laboratories, pilot plants, and production facilities, they comply with 3A, USDA, and FDA standards. Primary applications include cosmetics, food, and pharmaceutical manufacturing.
