The full set of deep cryogenic grinder is composed of feeding bin, mechanical pulverizer, induced draft fan, cyclone, vibration sieve, liquid nitrogen tank. In the process of pulverizing, the cold source comes into being a closed loop system, which makes full use of energy and save the engery.Cryogenic Equipment Fisher Scientific,Cryogenic equipment is used to contain liquid nitrogen (LN2) for controlled freezing and lowtemperature storage of biologic, genomic, and diagnostic samples. It may generate, sustain, or operate at extremely low temperatures and hold or assist with transportation of supercooled liquids or products that are perishable or not heat stable.
Cryogenic grinding,also known as freezer milling/ freezer grinding/ cryomilling is the act of cooling or chilling a material and then reducing it to smaller particle size. 2. Almost all materials embrittle when exposed to low temperature.Cryo Milling Cryogenic Grinding Union Process,Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling.
