Video demonstration shows machine Bagging Coarse Solar Salt into Plastic Open Mouth Bags with full flow and then a dribble.

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 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 plastic open mouth bag is ready for sealing.

Bagging Machine for Compost, Topsoil and Mulch has a specially designed horizontal belt feeder powered by a 3HP gear drive that is designed to fill semi and non free flowing materials into plastic open mouth bags. Compost, Topsoil or Mulch will be emptied into the supply hopper bin at the top of the machine. When a fill cycle is initiated, the product is conveyed by the belt feeder into the bag. The belt feeder is started by activating the foot pedal start switch. Once the feeder runs material for the preset time duration, the filling process will stop. Time of fill can be easily adjusted to achieve desired level of product into bag. Once the bag is filled, the operator moves the filled bag over the roller conveyor to the foot operated sealer. Bag is now ready to palletize.
