Air Products’ PolarFit® cryogenic grinding solutions can help you grind more effectively and efficiently, particularly for heat sensitive or tough-to-mill materials. Our systems use liquid nitrogen to cool down a feed material prior to and/or during milling to either help prevent its melting or decomposition, and achieve embrittlement.
We have experience with many mill types and can provide or recommend a feed or conveying system. Whether you have an existing cryogenic or ambient milling system that you need to upgrade, or plan to install a new system, we can help.

What equipment do I need to set up a successful cryogenic milling operation?
A cryogenic milling operation is very similar to a normal, ambient grinding operation. It can be set up in many different ways, but the basic components may include: the mill, a cryogenic conveyor, liquid nitrogen flow controls, a liquid nitrogen supply system, and then other supporting equipment common to normal, ambient grinding operations.
