Storage hopper
Stores granular material before weighing and includes an observation window
THREE-STAGE FEEDING GRANULE BAGGING MACHINE
Designed for accurate and efficient filling of 5–25 kg free-flowing granular materials into open-mouth bags.





PRODUCT INFORMATION
The YIHORA 5–25 kg High-Precision Three-Stage Feeding Granule Open-Mouth Bagging Machine is designed for accurate weighing and packing of free-flowing granular materials. The weighing system combines an arc-gate valve with a vibrating pan feeder to perform coarse, medium and fine feeding. This three-stage feeding process helps the machine approach the target weight quickly while maintaining stable final weighing accuracy. The standard weighing range is 5–25 kg per bag, with a reference packing speed of 6–8 bags per minute and a weighing accuracy of approximately ±0.2%. The complete packing system can include the bagging scale, storage hopper, belt conveyor and vertical double-thread bag sewing machine. Machine layout, hopper size, conveyor dimensions and electrical configuration can be customized according to the material, bag size and production requirements.
PRODUCT INFORMATION
PRODUCT INFORMATION
Granular material is first stored in the upper hopper and then enters the weighing system. At the beginning of the weighing cycle, the arc-gate valve supplies material rapidly for coarse feeding. As the measured weight approaches the target value, the feeding rate is reduced. The vibrating pan feeder then performs medium and fine feeding to control the final amount more accurately. When the preset weight is reached, the feeding system stops and the weighed material is discharged into an open-mouth bag held below the weighing unit. The filled bag is placed on the belt conveyor and transferred to the GK35-6A sewing machine. The bag mouth is sewn closed while the conveyor supports and moves the bag through the closing process.

PRODUCT INFORMATION




PRODUCT INFORMATION
It is designed for free-flowing granular materials such as plastic granules, feed pellets, grains, seeds, fertilizer granules and similar products.
The standard weighing range is 5–25 kg per bag.
The reference packing speed is approximately 6–8 bags per minute. Actual output depends on the material, target weight, bag handling and operating conditions.
The reference weighing accuracy is approximately ±0.2%, subject to the material characteristics and operating conditions.
The system uses coarse, medium and fine feeding stages to approach the target weight efficiently while controlling the final filling amount.
The machine combines an arc-gate valve with a vibrating pan feeder for three-stage material feeding.
The machine is designed for prefabricated open-mouth bags. The bag dimensions and material should be confirmed before quotation.
The standard system uses a GK35-6A vertical double-thread sewing machine to close the bag mouth.
A typical system includes the bagging scale, storage hopper, belt conveyor and bag sewing machine. Final supply scope depends on the selected configuration.
Yes. Hopper dimensions, conveyor length, conveyor height and machine layout can be customized according to the project.
Stainless-steel material-contact parts can be evaluated according to the product and hygiene or corrosion-resistance requirements.
Please provide the material name, particle size, bulk density, target bag weight, required capacity, bag dimensions, local power supply and destination country or port.
