Union Process Manufactures Newly Designed Pilot-Sized Mill Specifically for Cryogenic Grinding

Union Process, Inc. 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.

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