The name of the project is "Research and design, manufacturing equipment and mixed technology with more constituents product on the mixer drum machine". The authors have obtained the following results: Studied, designed and manufactured a cubic drum mixed machine: It worked well when changed the parameters of the machine in the research process. The mixed product is good as requirements. The results showed a mathematical model using regression of mixing: Y = 22,68 + 0,91X1 + 1,31X2 + 1,68X3. From this equation we have found a mixed mode by optimal Box-Wilson method with the parameters: The rotational speed of the barrel: X1 = 20 v/p
Score of barrels filled with mixed: X2 = 35 percent
The inclination of the mixed wing Co = 30°C. With this mode, the mixing time is 19 minutes to achieve one hundred percent uniformity. The mixing machine and mixed technology had been transferred to production facilities in Bac Ninh pharmaceutical company to mix medicine and have good results. It can mix dry separate different materials.
