Cryogenic Grinding | Cryogenics | Industrial Gases

Cryogenic size reduction utilizes the cooling effect of liquid nitrogen to embrittle materials prior to and or during the grinding process. Materials which are elastic in nature, which have low melting points, which have low combustion temperatures and which are sensitive to oxygen can be ideally machined by cryogenic grinding process.

grinding and crushing (Dean, 1995). Decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating. (See Section 12.3.1.2 for a discussion of the types of moisture present in solid samples.)

CRYOGENIC GRINDING AND IT'S APPLICATIONS

ADVANTAGES OF CRYOGENIC GRINDING Higher material removal rate can be achieved. Tool wear and tear is minimized to a great extent. Grinding forces are reduced. Cryogens act as coolant and hence the effects of overheating of the tool and work piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.
