Union Process Produces S-50 Attritor for Milling in Liquid Nitrogen



Akron, Ohio. . .Union Process, Inc., known globally as a manufacturer of size reduction and dispersing equipment for research and industrial applications, has produced a new S-Series Attritor. The new S-50 Attritor was specifically designed for cryogenic milling of aluminum powders.

The S-50 has a special cover with a Teflon shaft seal for ultimate grinding results at low temperatures. It features a vent port for liquid nitrogen as well as ports for thermocouples. The S-50 Attritor is designed with a jacket around the exterior of the tank to maintain full vacuum at temperatures as low as -320°F.

Featuring a gross tank volume of 81 gallons and a media volume of 37 gallons, this S-50 Attritor is constructed with a 40 HP motor with variable frequency drive (VFD). Since the mill was required to be explosion-proof, the VFD is mounted outside the hazardous area. In addition, an operator station with start/stop pushbuttons and a speed potentiometer plus a dual meter station is mounted on the machine. The dual meter station is programmed to display RPM and amperage but can also be programmed to display power consumption, percent torque, etc. The S-50 Attritor is ideal for long-term, heavy-duty operation. Weighing approximately 3,500 pounds without media, the mill is simple to operate and energy efficient. Because no special foundation is necessary, this versatile batch Attritor can be operated in virtually any location.
