The plastic, open mouth bag is clamped onto the outlet spout of machine. When 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 weight, the auger and conveyor slows down the flow to a dribble. When the target weight has been reached, the bag clamp is released and the plastic open mouth bag is ready for sealing.
The open mouth bagging machine shown in the video can fill open mouth bags with 20 – 100 pounds of material at a rate of 2 – 4 bags per minute. The target bag fill weight is controlled by a load cell with a digital controller. This machine can be fabricated from carbon steel with a powder coating or with stainless steel.
