Factors affecting the effect of winnowing
发布时间：2020-09-28 点击次数：
The impurity content of the raw materials will affect the efficiency of impurity removal. When the impurity content is high, the air volume can be appropriately increased. When the raw material contains more complicated impurities, multiple winnowing should be used in the cleaning process.
The state of the material entering the winnower:
The material spreads evenly along the working width and enters the separation zone continuously and stably. It is an important condition to ensure the effect of winnowing. Therefore, attention must be paid to the effect of feeding.
The speed of the material entering the separation zone should not be too high, and the direction of the speed should be as close as possible to the level, which is conducive to the updraft penetrating the layer and removing impurities.
The wind speed in the suction duct should be less than the lower limit of the suspension speed of the whole wheat, generally 6~7m/s.
