Union Process has manufactured a pilot-sized mill for cryogenic grinding with a specially designed stainless steel insulated cryogenic milling chamber.
 
"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 for Union Process.  
 
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.
