2,r=0.999 8;參照粉碎工藝參數(shù)范圍及生產(chǎn)實際,選擇連翹超微粉碎工藝條件為粉碎時間18 min,溫度?10~10 ℃,水分5%~9%,介質(zhì)填充率60%~70%,預(yù)測粒徑D50為22.56 μm,驗證粒徑D50為22.81 μm。結(jié)論 超微粉碎工藝條件參數(shù)與粒徑相關(guān)性良好,均勻設(shè)計法對超微粉碎工藝具有較好的指導(dǎo)意義。;Objective To optimize the technical parameters of ultramicro comminution for Forsythia suspensa by uniform design. Methods The scope of each comminution technology parameter was studied by using single-factor test, and the condition of ultramicro comminution technology was optimized by uniform design and stepwise regression. Results The stepwise regression equation was Y = 41.083-1.029X2, r = 0.999 8; According to the scope of each comminution technology parameter and the actual production conditions, the optimized technical conditions of ultramicro powder grinding of Forsythia suspense were as follows: grinding time 18 min, grinding temperature ?10—10 ℃, water content 5%—9%, medium filling rate 60%—70%, predicted particle diameter D50 22.56 μm, validation particle diameter D50 22.81 μm, which revealed that this equation had good practical guidance. Conclusion The relationship between ultramicro comminution technical parameters and particle diameter is very good, and the uniform design could guide the ultramicro comminution technology."/>
