Cryogenic grinding is a process where thermally sensitive and elastic substances are successfully processed by cooling with liquid nitrogen. The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during ...
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. The level of liquid nitrogen in the milling ...
Sep 01, 2003· The grinder used for grinding cumin seed was a laboratory model attrition mill. A cryogenic precooler (Goswami, 1998) was attached with the attrition mill. Both the precooler and the grinder were fed with LN 2 supplied from a pressurized LN 2 dewar through an insulated transfer line. The main function of the precooler was to remove the heat ...
Union Process Attritor Mill. The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area. Additionally, the attritor mill works at a higher rotation speed up to SPEED.
Our PolarFit cooling conveyors are ideal for the cryogenic size reduction of: • Hot melt adhesives • Pharmaceuticals • Pigments and powder coating materials The choice is yours Whether you're looking for a complete cryogenic fine grinding system or want to enhance your current mill's performance with the addition of a cooling con-
