A pseudo-particle size analysis instrument by optical line scan technology has been developed. The developed system composes of four major modules, which are materials feeding module, image acquired module, vision procession module and control unit. The main advantages of this system include total analysis without overlapping or missing of slipping particles, and pseudo-particle separation without breaking the granulation structure. The information gathered from the results covers pseudo-particle size distribution, mean size, roundness, sphericity, and uniformity. This is a powerful instrument for any kinds of small particle analysis.
