Union Process, Inc., known globally as a manufacturer of particle size reduction and dispersing equipment, as well as a supplier of grinding media and materials characterization services for a broad range of research and industrial applications, has manufactured a pilot-sized mill for cryogenic grinding with a specially designed stainless steel insulated cryogenic milling chamber.
Chuck Major, sales manager for Union Process, noted, "This unique mill features a special cryogenic controller with temperature probe to help maintain a consistent liquid nitrogen level in the milling chamber."
The S5 pilot-sized mill has a cryogenic cover with vent and a phase separator, along with two charging ports for added versatility. The mill has an actuated ball valve assembly that enables remote discharge of the liquid nitrogen slurry. Featuring a 10 HP explosion-proof motor and electricals, the mill also has a variable frequency drive to control agitator speed. The drive displays Hz, RPM and HP. An operator station is mounted on the unit with start/stop push buttons and a speed potentiometer.
Because the milling chamber tilts, maintenance and cleaning are easy and convenient.
Since 1946, Union Process has been developing and building custom Attritors for customers with a wide variety of applications all around the world.
