Fertilizer is sold in 50 kg bags, and a farmer notices when one is short. A plant bags thousands of tonnes a day, the subsidy and the invoice both run on weight, and a bagging line that drifts by a few hundred grams either gives product away or puts short bags on the market. Upstream, raw materials arrive by the truckload and move on conveyors to silos that nobody can see into.

Hindustan Scale Company (HSCo), Mumbai, has made weighing equipment since 1955. For fertilizer plants and blending units we supply bagging machines, heavy checkweighers, belt weighers, weighbridges and in-motion weighbridges, silo weighing, explosion-proof scales for rated areas, and scales with relay, 4-20 mA and RS-485 outputs for your control system. Tell us where the weight slips and we’ll name the equipment that holds it.

Where a fertilizer plant weighs, and with what

  • Raw material in – weighbridges and in-motion weighbridges for trucks of rock phosphate, potash and other inputs.
  • Conveyors – belt weighers measure material flow to the process and to silos.
  • Silos and hoppers – load cell modules show stock of raw material and product.
  • Blending – programmable and relay-output scales control each component.
  • Bagging – bagging machines fill 50 kg bags and heavy checkweighers reject short ones.
  • Dispatch – weighbridges for loaded trucks, pallet scales for stacks.

Raw material gate to bag stack, one supplier

Fertilizer plants weigh at the gate, on the conveyors, in the silos and at the bagging line. HSCo supplies all of it and links it to your control room.

  • Built for corrosive dust. Sealed load cells and protected electronics, because fertilizer dust eats ordinary scales.
  • Serviced. Installation, annual maintenance, repairs, upgrades and training.
  • Weights in the control system. Relay, 4-20 mA and RS-485 outputs from every scale.

Holding 50 kg, bag after bag

Bagging machines drift as the product’s density and flow change through the day. A heavy checkweigher after the bagger does two jobs: it rejects short bags before they reach a dealer, and its records show whether the bagger is creeping, so you can correct it before it gives product away. Protect both from dust, check them with a test weight each shift, and keep them stamped, because declared bag weights are a Legal Metrology matter.

Keeping scales alive in fertilizer dust

Fertilizer dust is corrosive and gets everywhere, so it shortens the life of any scale left unprotected. Keep indicators in closed housings, seal cable entries, clean platforms and load cells regularly, and choose stainless or well-coated parts near bagging lines. Check each scale with a test weight every shift, because a corroded load cell usually drifts before it fails.

Questions buyers ask

Weighbridges and belt weighers for raw material, silo weighing, programmable scales for blending, and bagging machines with heavy checkweighers at the bagging line. HSCo supplies all of them.

Yes. The HSC-FSBM fills 10 to 50 kg bags at ±0.1 to 0.5%, in automatic or semi-automatic versions.

Put a heavy checkweigher after the bagger. The HSC-PC500 / PC600 weighs bags up to 50 kg on the conveyor and rejects any outside limits.

Yes, over relay, 4-20 mA or RS-485 outputs.

Yes. Scales used to check declared quantities must be Legal Metrology verified and stamped.
