现在简单谈谈选粉机的工作方法(见图7)。核心部件是一个带径向通道(在图中只表示出一个通道,实际上有32条曲折的通道)的回转轮。物料从这个轮子的背面给入,并到达外壳和转子之间的环形缝隙中。附装的风机通过通道向图面抽风。在环形缝隙中产生了分离,粗物料随着空气穿过轮子并收集在旋风分离器里(图8)。 Now briefly talk about the working method of the separator (see Figure 7). The core part is a revolving wheel with radial passages (only one passage is shown in the figure, actually 32 winding passages). The material is fed in from the rear of this wheel and reaches the annular gap between the housing and the rotor. The attached fan draws air through the channel to the surface. Separation occurred in the annular gap, with the air passing through the wheels and collecting in the cyclone (Figure 8).
