搅拌机轴转速n是主要参数之一。适当地提高转速和增加搅拌时间可以改善砼的搅拌质量和提高效率,但线速度过大,在离心力作用下砼会产生离析现象,同时能耗和磨损大为增加。因此螺旋状搅拌叶片的线速度应有一个极限速度。为取得较好的搅拌效果,就必须选择较为合适的搅拌轴转速。单卧轴强制式搅拌机搅拌轴在旋转一周过程中要完成两种工作状态,即:当物料受到向上翻起并向下推动时相似于自落式搅拌
The mixer shaft speed n is one of the main parameters. Appropriately increasing the rotation speed and increasing the stirring time can improve the mixing quality and efficiency of the crucible, but the line speed is too large, and under the effect of the centrifugal force, the crucible can produce segregation phenomenon, and at the same time, the energy consumption and wear increase greatly. Therefore, the linear speed of the spiral stirring blade should have a limit speed. In order to obtain a better stirring effect, it is necessary to choose a more appropriate stirring shaft speed. Single-shaft forced-mixer agitator shaft to complete two working states in one revolution, that is: when the material is turned up and pushed down similar to self-falling stirring
