Introduction to 25 Kg Gross Weighing Machine Supplier
A 25 Kg Gross Weighing Machine is designed to weigh product directly into the bag (“gross” mode) and is ideal for industries packing fixed 25 kg bags of grains, sugar, chemicals, minerals, fertilizers, animal feed, and construction materials. As a trusted 25 Kg Gross Weighing Machine supplier, Samirika Industries Pvt. Ltd. provides PLC-controlled systems with high-precision load cells, pneumatic bag clamping, dust control, and seamless integration with conveyors, sewing or heat-sealing stations—delivering consistent accuracy, fast throughput, and hygienic operation for demanding plants.
Working Principle & Process Flow of 25 Kg Gross Weighing Machine
In gross weighing, the empty bag is clamped to the filling spout and product is dispensed directly into the bag while weight is measured in real time. A microprocessor/PLC monitors load cell feedback to control a two-stage feed (coarse + fine). When the target weight—typically 25.00 kg—is reached, feeding stops automatically. The bag releases to a take-away conveyor for stitching or sealing. Interlocks, alarms, and dust-extraction ensure safety, accuracy, and cleanliness throughout the cycle.
Types of 25 Kg Gross Weighing Machines
- Gravity Feed Gross Weighers — For free-flowing materials like rice, pulses, sugar, and salt.
- Belt Feed Gross Weighers — For semi-free-flowing granules such as fertilizers and plastic pellets.
- Screw Feed Gross Weighers — For powders including flour, cement, minerals, and chemicals.
- Single-Head vs. Dual-Head — Dual heads improve line speed for high-volume plants.
- Manual vs. Pneumatic Bag Clamp — Pneumatic clamping increases speed and consistency.

Applications of 25 Kg Gross Weighing Machine
- Food Grains & Pulses — Rice, wheat, dal, flour, sugar, and salt with hygienic handling and tight accuracy.
- Chemicals & Polymers — Powder/granule chemicals, plastic pellets, and additives with dust control.
- Fertilizers & Seeds — Urea, DAP, NPK, micronutrients, and hybrid seeds with consistent weights.
- Minerals & Construction — Cement, sand, limestone, bentonite, and fly ash in rugged duty cycles.
Benefits of Using 25 Kg Gross Weighing Machines
- High Accuracy — Reduced give-away and rework via PLC logic, fine feed, and stable load-cell weighing.
- Higher Throughput — Fast cycle times with dual-speed feeding and ergonomic bag handling.
- Lower Operating Cost — Minimal manual intervention, reduced spillage, and quick changeovers.
- Quality & Compliance — Better hygiene, dust control, and traceable batch data from the HMI.
Top Manufacturers & Suppliers in India
India has reliable suppliers for 25 kg gross weighers. Samirika Industries Pvt. Ltd. delivers PLC-based systems with gravity/belt/screw feed options and end-of-line integration. Other noted names include Payper India (bagging & palletizing solutions), VT Corp (bulk packaging systems), Sigma Instrumentation (industrial weighers), and Seal Pack (bagging lines). Selection should consider material flowability, desired speed, accuracy class, sanitation, and integration with existing conveyors and sealers.
Maintenance & Safety Tips
- Calibrate load cells on a defined schedule; verify zero and span before each shift.
- Inspect gates/valves, belts/screws for wear; keep the two-stage feed transitions smooth.
- Clean product-contact parts daily to prevent build-up and cross-contamination.
- Check air lines, filters, and clamps for leaks; maintain 6 bar stable pressure.
- Train operators on alarm codes, emergency stops, and safe bag handling practices.
