1 - Materials requiring cryogenic cooling prior to milling and cooling during milling operation as well
2 - Materials requiring cooling only for milling operation.
3 - The chilled gas generated as a result of heat transfer can be used for further application such as :
    - Pre- cooling of feed materials
    - Packaged products requiring longer self life
    - Other processes requiring innert environment
4 - Thus Optimal utilization of cryogens and improved scale of economy are attained.

Due to low boiling point and innert characteristic, Liquid Nitrogen and Liquid Carbon Dioxide are ideal for cryogenic reactive cooling and subsequent milling with homogenous heat transfer. Liquid carbon dioxide and liquid nitrogen provide sub-zero temperature levels down to minus 50°C and minus 150°C respectively. These cryogens are safe at use and environment friendly.

For fine pulverizing of many thermo plastics and other heat sensitive materials which are, otherwise, difficult to grind under conventional dry grinding.

Products containing valuable properties, like pungency, aroma, volatile matter, oil and fat, viscosity, moisture, texture, colour etc. are best pulverized retaining valuable properties to its maximum extent.

Innert property of cryo- media permit fine milling of explosive and hazardous products safely in addition to sub - zero temperature benefits mentioned above.

1- Valuable inherent properties are preserved to maximum extent.
2- Lower energy required for cryomilling than conventional dry milling process
3- No room for risk oxidation, fire and dust explosion during powdering process
4- Safe and environment friendly

Full fledged in-house test facility is readily available for pre-order or feasibility investigation on chargeable basis.
