Method for improving yield of mixed particles prepared by boiling method and application

The invention belongs to the technical field of particle preparation, and particularly relates to a method for improving the yield of mixed particles prepared through a boiling method and application. The method comprises the following steps: (1) screening an inner core material; (2) screening a shell material; (3) conducting particle size screening: selecting an upper limit value of prepared target particles as a D mesh value, and screening inner core particles with the particle size of D and shell particles with the particle size of D in combination with a correlation formula; and (4) conducting granulation: performing boiling granulation on the core particles and the shell particles according to the mass ratio of m:m to obtain the granular material. According to the present invention, the core particles and the shell particles in the boiling method granulation are screened, the related wind speed (or wind pressure) is determined by combining the stress analysis during the boiling granulation for the first
