| description | The invention provides a nano-powder granulator and a preparation process, and the preparation process comprises the following steps: raw material preparation: selecting proper raw materials, crushing the raw materials to a proper size according to needs, and meanwhile, fully drying the raw materials; heating and evaporating: heating the raw materials to a high enough temperature to evaporate or sublimate the raw materials; melting and solidifying: heating the raw materials to a melting point to melt the raw materials, and then gradually cooling to room temperature to solidify the raw materials; performing spray granulation: performing granulation operation on the raw materials by adopting a nano-powder granulator; high-temperature lifting furnace treatment, wherein the nano powder particles are heated, smelted and sintered through a high-temperature lifting furnace; and surface modification: adding a surfactant into the nano powder particles. According to the device, the electromagnet is matched with the fir |
