A real production line has an order — each machine exists because of what happens right before and right after it. Here’s the full sequence, stage by stage.
Wheat straw, paddy stubble, cotton stalk, mustard husk or other agricultural residue arrives at the yard — usually loose, baled, or in bulk trailers. This is the raw material Punjab already produces in enormous volume every harvest.
The dual-roller shredder (or round-bale shredder, for whole bales) cuts material down to a consistent, manageable size — the first real reduction from field-scale bulk to processable feedstock.
Shredding throws up fine dust. The pulse jet system pulls it through a bag filter and cleans itself with automatic reverse-air pulses, so the plant stays compliant and breathable without interrupting the line.
Shredded material feeds into the hammer mill, where swinging hammers pulverise it into a fine, even powder. Screen size is chosen to match the exact particle size the pellet die needs downstream.
If moisture content is above what the pellet mill needs (10–12%), a rotary or flash dryer brings it down first. Skipped for already-dry feedstock, this stage is what determines pellet strength and shelf life.
Fine, moisture-controlled powder is fed — via automatic or twin-screw feeder — into the ring-die pellet mill. Rollers press it through hardened die holes under heat and pressure, binding it into dense pellets using nothing but the biomass’s own natural lignin.
Fresh pellets are hot and slightly soft straight off the die. They’re cooled, screened to remove fines and broken pellets, then conveyed to bagging or bulk storage — ready to fuel a boiler, furnace or gasifier.
Line Design
Moisture content, straw type, and target output all change which machines and capacities make sense. That’s why we design the layout before we quote the machines.
Wheat straw, paddy stubble, and cotton stalk all behave differently under a hammer mill and die. We start there.
Capacity, motor sizing, and die selection are calculated for your target output — not sold off a standard catalogue.
A single CAD layout showing every machine, conveyor and clearance — so installation goes exactly to plan.
