Introduction to impurity removal of flowering machine: Different flowering machinery, the radian of the dust grid, the number of dust rods and the distance between the dust rods are different, and the selection is mainly based on the nature of the raw material and the processing requirements. For example, cotton spinning opening machines mostly use triangular cross-section dust rods, which have a better effect on removing impurities. The dust rod with a circular cross-section is commonly used in wool spinning opening machines to avoid damage to the scales of the wool fiber. In order to remove various impurities during the opening of the raw materials, a grid-like dust grid composed of several dust rods is generally installed around the beater. The whiskers fed to the roller are affected by the high-speed rotating beater. The separated fiber blocks and impurities are thrown into the dust grid and collide with the dust rod. The fiber blocks are retained by the dust rod, and the impurities fall from the gap between the dust rods. Then, the fiber block moves forward under the action of the beater's blow and the air flow.
