Union Process Produces SDL-30 Batch Attritor for Grinding Under Liquid Nitrogen

Akron, Ohio. . .Union Process, known globally as a manufacturer of size reduction and dispersing equipment for research and industrial applications, has manufactured a custom model SDL-30 dry grinding batch Attritor for a customer producing desiccants (sorbents) for the food, pharmaceutical, medical/diagnostic and electronics industries.

This SDL-30 Attritor has a special cover with a Teflon shaft seal for grinding under low temperatures. It features a vent port for liquid nitrogen as well as two ports for charging separate ingredients.

Featuring a gross tank volume of 52 gallons, the mill is constructed with a 50 HP motor with a variable frequency drive (VFD). The controller is installed in a separate enclosure and displays RPM, percent load (torque) KW, amperage, Hz, and output voltage. The operator station, mounted on the Attritor, includes start/stop pushbuttons and a speed potentiometer. The mill was also specified to have specially configured arms to improve milling efficiency.

Union Process batch Attritors are ideal for long-term, heavy-duty operation. The mills are easy to operate, energy efficient, and up to ten times faster than a traditional ball mill. Also, because no special foundation is required for an Attritor, the versatile mill can be operated in virtually any plant location.

Union Process is the inventor and developer of Attritor technology and manufactures wet and dry grinding mills as well as small media mills.
