Material behavior / 物料行为
The fine powder may generate dust, pick up moisture, cake, or stick. Fine powders can entrain air during conveying, feeding, and filling, increasing the internal air content of the filled material.
Feeding method, hopper flow assistance for poor-flowing grades, weighing stability, and dust collection should be considered. Deaeration or air-release measures may be considered for filled bag stability, bag transfer, closing, and palletizing. When heat sealing is used as the closing method, powder residue in the sealing area should be controlled to avoid sealing defects.
