【Abstract】 During the cryogenic grinding process of scrap tire peels, transient heat transfer happens in the vortex mill and the cynclone.The temperature distribution within a scrap tire peel was calculated by a numerical method of transient heat transfer. The optimal temperature of the compressed airneeded in the vortex mill was also founded by experiments and compared with the calculated result. The proposed calculating method may be appliedin the design of the cryogenic grinding process for recovering the cold--energy stored in the fine powders.更多还原
