Many people don't understand how the screw measures the weight? How can the weight error be reduced?

Generally, the metering and feeding parts of the powder packaging machine are sealed to reduce dust. Therefore, it is more difficult to know how the powder is measured.
In fact, the screw powder feeder realizes the adjustment of the weight by adjusting the speed of the screw and the number of rotations. The greater the rotation speed of the screw and the greater the number of turns, the more material will be cut and the greater the weight. The fewer the number of screw turns and the lower the rotation speed, the less the material is cut and the lighter the weight.
