The time for graduate students to review blindly is generally in March-April, and it usually takes 2-4 weeks. Even some people's papers may take more than a month to review before they can give feedback on revisions. The actual time required is subject to the time of the blind reviewer. If the blind review fails, it will take 3~6 months to revise before it can be submitted again. Therefore, before submitting a paper for blind evaluation, please ensure that there are no major errors in the format and content of the paper.
