The Charlotte Colloid Mill combines the forces of hydraulic shear, centrifugal action, and impact on the product via the distinctively designed grooved rotor and stator. The high-tolerance clearance between them is regulated by an externally calibrated adjustment device assuring a consistent mill setting throughout the product run. All process materials are fed between the mill’s unique stator and rotor assembly revolving at 3600 rpm, resulting in the processed materials being dispersed, suspended, emulsified, homogenized or comminuted with the finest results. It is used for products such as mayonnaise, salad dressing, pharmaceutical creams, lotions, ointments, cosmetic fragrances, facial creams, and body lotions. The “SD” Series models are fabricated from type 316 stainless-steel in the process area for sanitary application. Product processing chambers are fully jacketed for optional heating and/or cooling. Products to be processed must be in a pumpable slurry. All units are non-aerating, high shear, in-line equipment that can be fully calibrated in increments of 0.001." The mill’s horizontal design lends itself to inline installation. Together, with its “user-friendly” assembly for easy maintenance and non-aerating production chamber, the mill may be used for either batch or continuous processing. Its unique hydraulic shear and centrifugal- action production chamber allows the mill to process the most viscous products. The Charlotte Colloid Mill can be easily cleaned in place.
