Introduction to 25 Kg Net Weighing Machine Manufacturer
The 25 Kg Net Weighing Machine is a high-accuracy, high-throughput solution designed for bagging powders and granules into open-mouth bags with precise net weighing. Ideal for food, chemical, fertilizer, mineral and feed industries, it delivers consistent accuracy, faster cycles, and minimal product giveaway. Samirika Industries Pvt. Ltd. manufactures robust, microprocessor-controlled net weighers with options for gravity, belt, screw, or vibratory feeders, along with conveyor, sealing, and stitching integration for fully automated bagging lines.
Working Principle and Process Flow of 25 Kg Net Weighing Machine
In a net-weigh system, the product is pre-weighed in a weigh hopper before being discharged into the bag. The feeder (gravity/belt/screw/vibratory) fills the hopper in coarse and fine feed stages. Load cells and a controller monitor live weight, switch to dribble feed near the setpoint, and close the gate precisely at 25.00 kg (adjustable). The filled hopper opens, transfers the product into the bag on the spout, and the bag automatically moves to sealing or stitching via a conveyor—ensuring clean, dust-controlled, and repeatable packing cycles.
Types of 25 Kg Net Weighing Machines
- Gravity Feed Net Weigher – For free-flowing products (rice, grains, sugar, salt, pellets).
- Belt Feed Net Weigher – For semi-free-flowing granules (fertilizers, seeds, plastic granules).
- Screw Feed Net Weigher – For fine powders (flour, atta, chemicals, minerals, cementitious powders).
- Vibratory Feed Net Weigher – For delicate or lightweight materials requiring gentle handling.
- Dual-Head / Multi-Head Net Weigher – Parallel weighing heads for higher output per minute.
Key Features and Specifications of 25 Kg Net Weighing Machine
- Microprocessor/PLC-based controller with coarse/fine feed logic for ±10–50 g typical accuracy*.
- High-quality load cells and anti-drift compensation for stable, repeatable results.
- Hopper with pneumatic gates, dust hood, and bag clamp with safety interlocks.
- Throughput up to 6–12 bags/min (product and model dependent) with quick recipe changeover.
- Seamless integration with conveyors, bag top sealer or industrial bag stitching units.
Applications of 25 Kg Net Weighing Machine
- Food & Agro – Rice, wheat, pulses, flour, sugar, spices, seeds with hygienic, accurate bagging.
- Chemicals – Powder and granular chemicals with dust-controlled, precise filling.
- Fertilizers – Urea, DAP, NPK and specialty nutrients in rugged open-mouth bags.
- Minerals & Construction – Sand, silica, bentonite, lime, and mineral powders with consistent weights.
- Animal Feed – Pellets and mash packed with minimal giveaway and high line efficiency.
Benefits of Using 25 Kg Net Weighing Machine
- High Accuracy – Tight tolerances minimize product giveaway and ensure compliance with packing norms.
- Higher Productivity – Faster weigh-dump cycles with dual-stage feeding and automated transfer.
- Lower Operating Cost – Reduced manual handling and rework; consistent bag quality.
- Clean Operation – Dust extraction points and enclosed flow paths improve workplace hygiene.
