Cryomilling System (Sub-zero Temperature Milling ) ensures a
perfect blend of product characteristics, cryo-media and engineering
requirement based on our pulverizing / milling experience since
1965.
Cryomilling System is an ideal solution, where the resulting
frictional heat in conventional dry grinding is extremely
detrimental to end quality of powders.

Cryomilling Recommendation : |
|
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.

Cryo
- Media used : |
|
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.

Cryo
- Milling Application : |
|
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.

|
Cryomilling Advantage : |
|
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
