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.
From cryogenic services, industrial gas supply, to complete cryogenic systems, you can rely on Air Products experienced engineers to help you find the best solution for your process.
Over three decades of laboratory and plant experience in cryogenic grinding… Not tied to one mill manufacturer, enabling us to provide a range of options… Flexibility in trial facilities/process… A range of efficient cooling conveyor options.
Technology Manager - Cryogenic Applications
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.
