description The invention belongs to the field of powder detection, and discloses a method for detecting dry powder mixing uniformity. The method comprises: S1, uniformly mixing a to-be-mixed powder according toa preset ratio to obtain a mixed powder; S2, calculating the theoretical particle size of the mixed powder according to the particle size and the proportion of the to-be-mixed powder; S3, randomly taking the powder in the mixed powder as a sample and flatly paving the sample; S4, testing the sample by using a laser particle size analyzer to obtain the actual particle size of the mixed powder; andS5, calculating a relative deviation between the actual particle size in the step S4 and the theoretical particle size in the step S2, and judging the mixing uniformity according to the relative deviation. According to the invention, the actual value of the particle size of the mixed powder is obtained through testing, the theoretical value of the particle size of the mixed powder is calculated through the particle size an
