Abstract: A high-efficiency particle analysis method includes the following steps: taking representative air-dried samples and measuring a moisture content; boiling, sieving, weighing and adding a dispersant; conducting a particle analysis test; reading four readings of 1st to 59th and 60th to 90th samples; and drawing a particle size distribution curve showing the relationship between the particle size and the percentage of below a certain diameter. According to the method, a time difference is used to change the measurement mode, and the four readings of the 59th and 90th samples are read in a cycling manner; and a novel test method is provided on the premise of ensuring quality, thus greatly improving the efficiency of a particle analysis test and meeting production requirements.
