Union Process Laboratory Cryogenic Grinding System

Akron, Ohio. . .Union Process, Inc., known globally as a manufacturer of size reduction and dispersing equipment for a broad range of industrial applications, has developed a system for controlling the flow of liquid nitrogen into the grinding chamber for customers performing cryogenic grinding.

The engineered system includes a probe inside the grinding chamber that monitors the temperature, and at the same time, regulates the flow of liquid nitrogen into the mill to maintain the desired temperature. Raising and lowering the temperature is accomplished by simply adjusting the dial up or down. The device is then able to change the rate of flow of liquid nitrogen into the chamber to achieve this goal.

The system pictured was designed for use with Union Process 01-HD and 1-S Laboratory Attritors, however the system can also be adapted for use with production-sized mills as well.

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