The coolant used in the MQL is mainly synthetic oil or mineral oil [123, 124]. ... When cryogenic grinding the difficult-to-cut alloys such as superalloy, titanium alloy, or hardened steel, the specific grinding energy (the energy consumed by removing unit material) decreases by 33% than the grinding with conventional cooling, the …
Cryogenic grinding, namely freezer grinding or cryomilling [36], is among the advanced grinding methods that allows finer particle size via grinding operation at extremely low temperature,...
The cryogenic grinding tests results show that, compared with that of room temperature, the content of the nickel-cobalt-manganese-lithium in the −0.15 mm particle size was increased from about 16–84%, the graphite content from 31.55% to 90.58%, and the content of aluminum and copper in the +1 mm grain size increased from 79.32% and …
Therefore, cryogenic grinding could realize the selective grinding of the cathode and significantly improve the peel-off of the electrode materials. The peel-off efficiency of cathode materials was improved from 25.03% to 87.29% at the optimum conditions of low temperature pretreatment for 5 min and cryogenic grinding for 30 s.
In the following, the theoretical background of cryogenic grinding and a new technology based on an alternative cooling equipment are presented. With the alternative technology, the operation costs during cold grinding will be drastically reduced.
