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.
Cryo Milling System is an ideal solution, where the resulting
frictional heat in conventional dry grinding is extremely detrimental to
end quality of powders.

Cryo Milling System 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

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