Union Process, Inc. recently announced that it has manufactured a pilot-sized mill for cryogenic grinding that reportedly includes a specially designed stainless steel-insulated cryogenic 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 also features an actuated ball valve assembly that enables remote discharge of the liquid nitrogen slurry.

With 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 reportedly easy and convenient.

“This unique mill features a special cryogenic controller with temperature probe to help maintain a consistent liquid nitrogen level in the milling chamber,” said Chuck Major, sales manager.
