Union Process Produces Special Metal-Free Circulation Attritor for Medical Customer

Akron, Ohio...Union Process, Inc., known globally as a manufacturer of size reduction and dispersing equipment as well as related services for a broad range of industrial applications, has produced a special Q-6 Circulation Attritor for a start-up orthopedic medical company.

To ensure a metal-free environment as required by this customer's application, the Attritor was constructed with an 8.5-gallon, polyurethane-lined grinding tank and a plastic-coated agitator shaft with polyurethane-coated agitator arms. The upper discharge chamber was constructed of Halar-coated stainless steel.

Q-Series mills from Union Process are high-circulation, high-flow mills, which produce a faster grind and narrower particle size distribution. During the circulation process, the material makes multiple passes through the grinding chamber until the desired particle size is obtained. This means that Q-Series mills can process a large batch of slurry using a smaller mill, which requires less grinding media. That can provide a significant cost savings.

The mill is powered by a 10 HP T.E.F.C. motor with a variable frequency drive (VFD). The controller features an LCD operator interface module programmed to display agitator RPM, motor amperage, and HP use. The system was completed with an air-operated, diaphragm pumping assembly and a separate 75-gallon premix/holding tank with a turbine mixer and an anchor stirrer.

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