Spiral feeding machine for producing superfine composite admixture

The utility model relates to the technical field of superfine composite admixture production equipment, and particularly discloses a spiral feeding machine for superfine composite admixture production. Comprising a conveying cylinder which is provided with a feeding port and a discharging port and is arranged in an inclined mode, an output shaft coaxial with the conveying cylinder, a spiral blade installed on the output shaft and a driving device connected with the output shaft. And the screw pitches of the spiral blades are sequentially increased from the feed port to the discharge port. According to the feeding device, the problem that the spiral blade is clamped in the feeding process is effectively avoided, and the working efficiency is effectively improved. 本实用新型涉及超细复合掺合料生产设备技术领域，具体公开了一种超细复合掺合料生产用螺旋上料机，包括设置进料口和出料口且倾斜设置的输送筒、与输送筒同轴设置的输出轴、安装在输出轴上的螺旋叶片以及与输出轴连接的驱动装置；所述螺旋叶片的螺距由进料口向出料口方向依次递增。本实用新型有效的避免上料过程中出现卡螺旋叶片的问题，有效的提高工作效率。
