  • Optimised technologies for cryogenic grinding

    At Fraunhofer UMSICHT, a low-temperature fine-grinding plant in technical scale was erected for research. Investigations for optimisation of cooling equipment resulted in the development of an innovative technology based on cooling technology. With this technology, the usage of lN 2 could be dramatically reduced.

  • Optimised technologies for cryogenic grinding

    2004-12-10 · The heat to be discharged at cryogenic grinding is composed of heat, which has been introduced by the product (Q˙ feed) and the heat introduced by the drive capacity of the mill (Q˙ mill), provided that the grinding air flow required for the operation of the mill is met by the condensing nitrogen alone. (8) Q ˙ total = Q ˙ feed + Q ˙ mill

  • Retsch : Retsch : 下载 : 应用报告

    CryoMill Cryogenic grinding was never more convenient or efficient Some sample materials have properties which make size reduction at ambient temperature impossible. If, for example, very elastic materials need to be ground or volatile components have to be preserved for further analysis, it is essential to carry out cryogenic grinding.

  • HOW TO GUIDELINES SPEX® SamplePrep

    2016-10-19 · Success in Freezer/Mill cryo-grinding depends on two main things: The sample must be cold enough to be brittle. The impactor must be able to move freely back and forth. The quantity of sample per load and the size of the sample pieces can heavily a˚ect the grinding e˛ciency of the mill, particularly with bone, which can be very tough.
