Description
The SDBY series small bag packing scale is a gross-weighing packing unit designed for open-mouth bags of 15-50 kg. Material is fed from the hopper through a gravity or belt feeder into the bag hanging on the scale hook; when the target weight is reached, feeding stops automatically and the bag is released for sewing or heat sealing. It is a compact, budget-friendly choice for small and medium plants that need accurate weights without a fully automatic bagging line.
Features
1.Quick-change feeding gate: the feed outlet is sized for interchangeable gravity and belt feeders, so one scale can switch between powder and granular products in minutes.
2.Panel-based operation: target weight, coarse/fine feed cut-off, and batching counts are all set from the front panel — no specialist training needed.
3.Automatic process control: feeding speed, dosing, and bag release run automatically once the target is confirmed.
4.Dual weight display: the imported intelligent weighing indicator shows gross and net weight at the same time, so operators always see real net output.
5.Automatic tare: bag weight is deducted automatically for every cycle.
6.Automatic zero tracking keeps the scale drift-free through long shifts.
7.Weighing error detection and self-correction alarm.
8.Production management ready: total packages, gross/net totals can be exported to a computer or printer for quantitative management.
9.Integrated dust extraction port keeps filling dust inside the enclosure and improves the working environment.
10.Packing range: 15-50 kg per bag.

Typical Applications
- Feed plants: dosing and packing of 15-50 kg bags of pellets, premix, and crushed feed
- Grain & seed processing: weighing packed rice, wheat, maize, and vegetable seeds
- Biomass: bagging of wood pellets and briquettes for retail bags
- Chemical & mineral powders: bentonite, gypsum, and masterbatch in moisture-proof bags
Frequently Asked Questions
Q: What accuracy can I expect in daily production?
A: With gravity feeding and a stable product, dynamic weighing accuracy is typically ±100 g on a 25 kg bag; fine-feed tuning brings it closer to ±50 g. Actual accuracy depends on product flowability and bag handling.
Q: Which model should I choose between SDBY-F, SDBY-I, and SDBY-II?
A: The difference is the feeding mechanism and speed class: belt-fed models suit free-flowing pellets, screw-fed models suit powders, and the twin-hopper SDBY-II(S) doubles throughput for 10-18 bags per minute. Tell us your product and target capacity and we will recommend the configuration.
Q: Can it connect to our bag sewing machine and conveyor?
A: Yes. The scale output can be linked to a bag-closing conveyor so that weighing, sewing, and counting run as one line; package counts can be sent to your printer or plant system.
