Introduction


The term “Cryogenics” originates from Greek word which means creation or production by means of cold.
As prices for energy and raw materials rise and concern for the environment makes safe waste disposal difficult and Costly, resource recovery becomes a vital matter for today’s business.
Cryogenic grinding technology can efficiently grind most tough materials and can also facilitate Cryogenic recycling of tough composite materials and multi component scrap.



What is Cryogenic Grinding


Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size.




CRYOGENIC GRINDING TECHNOLOGY



For pulverizing many materials, cryogenic grinding technology increases productivity and lowers power costs.
Many elastic or "soft" materials are very difficult to pulverize, requiring long cycle times and high energy consumption.
This combination decreased productivity and increased costs unnecessarily.
Cryogenic grinding involves cooling a material below its embrittlement temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide.



ADVANTAGES OF CRYOGRINDING


Higher production rate.
Lower energy consumption.
Finer particle size .
More uniform particle distribution.
Lower grinding cost.
No heat generation which is good while grinding spices, pharmaceuticals and scrap plastics.
Provides an inert atmosphere thus eliminating the possibility of oxidation.
