G Models for Lubricating Grease Production

The most successful and time tested, Charlotte Colloid Mills, are used for processing the full range of NLGI and ILMA type lubricating greases including; Lithium, Sodium, and Calcium soap base and other non-soap greases.

Whether our “G” Series for industrial applications or the “SD” Series for sanitary applications, both lines of equipment work within the same design parameters. Product processing chambers are fully jacketed for optional product heating or cooling. All Charlotte Mills may process materials up to 400°F and withstand product throughput pressures up to 150 PSI (100 PSI on the “SD-2” stainless steel product area). Products to be processed must be in a pumpable slurry. All units are non-aerating, high shear, inline equipment and can be fully calibrated in increments of .001-inch rotor/stator clearances by external adjustment assembly. Manufacturing clearances can be set from .005 inches to .070 inches. Average micron particle size that can be achieved is usually between 3-5 microns.

Designed to perform and produce outstanding results continuously and reliably, the Charlottes are considered the standard by which excellence is measured.
