Akron, Ohio– Union Process announced the development of a new S5 polyurethane-coated Attritor for a customer in the semiconductor and photonics industries. This project required a solution with highly technical specifications to optimize the material output.

Union Process sales manager, Brian Li, said, “The customer will be using ceramic zirconium oxide yttria grinding media for this metal-free wet milling application, which ensures optimal particle size reduction, uniform dispersion, and high grinding efficiency. This approach will also aid in minimizing contamination in the final product.”

The Attritor is powered by a 10 HP, totally enclosed fan cooled (TEFC), inverter duty motor. The 460V/3PH/60Hz variable frequency drive has a NEMA 4X controller enclosure and the LCD Human Interface Module (HIM) is programmed to display agitator RPM and motor HP.

The grinding tank is stainless-steel, polyurethane-coated, and jacketed for temperature control. The agitator assembly is comprised of a plastic-sleeved stainless-steel shaft with polyurethane coated steel reinforced agitator arms. The system is completed with a two-piece, plastic Ultra High Molecular Weight Polyethylene (UHMW) cover.

Union Process is a global manufacturer of particle size reduction and dispersing equipment, a supplier of grinding media and a provider of material characterization services for a broad range of research and industrial applications. Since 1946 the company has been developing and building custom Attritors. Union Process invented and developed Attritor technology and manufactures wet and dry grinding mills as well as horizontal bead mills. Attritor is a registered trademark of Union Process, Inc.
