Professional gravity-fed valve bag packing machine for fertilizer, sand, and plastic pellets. No electricity required for basic operation. Features gross weighing and 3 bags/min speed
Streamline your bulk packaging with our Gravity Feeding Valve Bag Filler. This rugged, high-efficiency system is the premier choice for packaging free-flowing granular and pelleted materials. By utilizing the natural force of gravity, this machine simultaneously fills and weighs product directly into valve bags, eliminating the need for complex internal motors or high energy consumption.
Specifically designed for materials with high fluidity, such as fertilizer, sand, salt, and plastic pellets, our gravity packer delivers a reliable, cost-effective solution for bags ranging from 20 to 110 pounds.
The primary advantage of the Gravity Fed Valve Bag Filler is its mechanical simplicity. For basic operations, no air or electricity is required, making it an exceptionally durable "set-and-forget" machine for harsh industrial environments. Its integrated Gross Weighing System ensures that the bag is weighed as it is filled, guaranteeing accuracy without secondary steps.
Zero Energy Requirement: Operates via gravity for basic filling, significantly reducing utility costs and maintenance complexity.
Dual Filling & Weighing: Simultaneously fills and weighs product directly into the bag for maximum efficiency.
High Durability: Engineered for heavy-duty materials like limestone, refractory products, and sand.
Ease of Use: Simple clamshell gate mechanism provides a clean "start/stop" flow, minimizing material waste.
Integrated Dust Control: Includes dust collection ports to maintain a clean and safe working environment.

This machine is highly effective for any free-flowing granular or pelleted material, including:
Agriculture: Fertilizer, Corn, Soybeans, Seed.
Food & Mineral: Salt, Sugar, Sand, Limestone.
Industrial: Plastic Pellets, Refractory Materials, Decorative Stone.
Bag Installation: The operator slides the valve bag onto the funnel-shaped fill spout.
Filling Sequence: Once triggered, the clamshell gate opens.
Automatic Cut-off: As the bag reaches the designated weight on the scale, the clamshell gate automatically snaps shut.
Removal: The filled bag is removed from the spout, and the scale resets for the next cycle.
