The demonstration video below shows an open mouth bagger packaging coarse solar salt into plastic bags at full and dribble flow speeds.
The bag is clamped onto the outlet spout of the machine. When the start button is pressed, the coarse solar salt is conveyed into the bag at full flow. When the contents of the bag get close to the target fill weight, the auger and conveyor slow down the flow to a dribble. When the target weight has been reached, the bag clamp is released and the bag drops so it can be picked up for sealing.
