Title:
POWDER COMPOSITION AND PARTICLE SIZE CONTROL SYSTEM, AND CONTROL METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2021/227244
Kind Code:
A1
Abstract:
A powder composition and particle size control system and a control method for the system. The control system comprises: a material crushing bed unit, a grading unit, a fine grinding unit, and a mixing unit. The material crushing bed unit is used to crush a raw material into material particles, and convey the particles to the grading unit. The grading unit is used to grade the material particles into particle groups having different particle size range distributions. The graded particle groups having different particle size distributions comprise small-diameter particles, medium-diameter particles, and large-diameter particles. The medium-diameter particles are ground by the fine grinding unit to obtain micro-diameter particles having an average particle size less than that of small-diameter particles. The invention uses a crushing bed-based hybrid powder grinding technique, utilizes a grindability difference of different materials, and achieves, by means of grinding and mixing system units, controllability of powder compositions and particle sizes within different particle size ranges, thereby realizing an optimal effect for powder usage.
