To screen the microcapsules with an ordinary powder screening machine, they need to be crushed first and then screened. This complicated process leads to low powder making efficiency and easily causes dust pollution. Therefore, it is necessary to design a special microcapsule powder making machine that combines crushing and screening functions. Utility Model Content
