 摘  要
 雙軸攪拌機為螺旋式攪拌機，它的攪拌部件是兩根形狀對稱的同步螺旋轉子，兩根螺旋軸在旋轉時速度同步、方向相反。雙軸攪拌機由電機驅動，可用減速機控制轉子轉動速度，達到最佳的攪拌效果。
 雙軸攪拌機的主要部件包括，機械外殼、兩根螺旋轉軸、電機驅動裝置、聯動裝置、配管和蓋板等，雙軸攪拌機的螺旋軸是最重要的工作部分，兩根螺旋軸的旋轉方向相反，都具有軸承座、軸承套、軸承蓋、葉片和聯動裝置。攪拌機構包括彼此平行的第一和第二攪拌軸、攪拌葉片和臥式攪拌桶，所述攪拌葉片從第一和第二攪拌軸向四周伸出，并在軸向依次等距排列而在圓周方向依順時針或逆時針彼此相差一固定角度，使在第一和第二攪拌軸上的攪拌葉片分別形成旋向相反的螺旋狀排列；所述第一和第二攪拌軸彼此同步轉動并且其葉片交錯通過由該第一和第二攪拌軸軸線所確定的平面；在所述攪拌桶一端的頂部設有進料口，而在所述攪拌桶另一端的底部設有出料。采用這種結構，攪拌機的攪拌葉片在攪拌干粉砂漿的同時將干粉砂漿從進料口排向進料口，從而實現生產的連續，有效的提高了生產效率。

Abstract
 Biaxial mixer spiral mixer to its mixing two symmetrical parts are synchronized helical rotor, two screw shaft rotation speed synchronization, in the opposite direction. Biaxial mixer driven by a motor, can control the rotor rotation speed reducer, to achieve the best mixing results. The main components include biaxial mixer, mechanical enclosure, two screw shaft, motor drive, interlocks, piping, and flat tops, dual-axis mixer spiral axis is the most important part, the two helical axis of rotation in the opposite direction , have a bearing, bearing units, bearing caps, leaves and interlocks. Mixing with each other parallel institutions, including the first and second stirring shaft, stirring blades and horizontal mixing barrel, above mixing blade from the first and second axial four weeks out of mixing and axial offset in turn arranged in circle clockwise or counterclockwise direction according to a fixed point of difference with each other, so that in the first and second axis of the mixing blades were stirring the formation of the spiral spin arrangement to the contrary; the first and second mixing shafts rotate simultaneously with each other and their leaves staggered through the mixing of the first and second axes defined plane; in above the top end of the mixing bucket with feed, while the other end of the said mixing drum with the material at the bottom. Using this structure, the mixing blade mixer mixing dry powder in the mortar, while the dry mortar from the inlet to the inlet arrangement in order to achieve continuous production, effectively improve the production efficiency.
 Keywords: biaxial mixer efficiency helical mixing blade shaft
