Step 4
Optional palletizing and stretch wrapping complete the line
Model options & specifications
| Model | Type | Power | Capacity | Dimensions | Weight | Note |
|---|---|---|---|---|---|---|
| SXWP-001 | Packing machine | by model | 4–6 bags/min | by model | — | 20–50 kg/bag · error ±0.2% · sewing machine + conveyor + control cabinet |
| SXWP-002 | Hopper packing machine | by model | 6–8 bags/min | by model | — | 20–50 kg/bag · error ±0.2% |
| SXWP-003 | Double-silo packing machine | by model | 6–13 bags/min | by model | — | 20–50 kg/bag · error ±0.2% |
| SXWP-004 | Double-station packing machine | by model | 6–13 bags/min | by model | — | 20–50 kg/bag · error ±0.2% |
How to choose a model
Models are sized by throughput. Pick the model whose rated capacity is closest to your target output with 15–20% headroom. If your project falls between two models, our engineers will recommend the most economical option — oversizing is rarely the cheapest answer.

How we guarantee every machine
Quality is a process, not a label — every YUSHUNXIN machine passes the same five checkpoints before it leaves the factory.
Incoming material inspection
Steel plates, motors, reducers, bearings and electrical parts are checked against brand and specification on arrival.
Fabrication & welding inspection
Shell thickness, welding quality, alignment and surface finish are inspected at each station during fabrication.
Assembly & alignment check
Shafts, gears, rollers, frames and drives are aligned and checked before electrical hook-up.
No-load test run
Every machine is test-run no-load; speed, vibration, noise and temperature are recorded on the test sheet.
Packing & pre-shipment check
Export packing, spare-parts list and documents are double-checked, with photos/video before dispatch.
Packing, delivery and after-sales
Export packaging
Machines are packed for sea freight: steel-frame or plywood cases, anti-rust treatment, waterproof film and clear marking.
Worldwide delivery
FOB, CIF, CFR or door-to-door options; we prepare packing lists, commercial invoices and shipping marks for customs.
Installation & commissioning
Site drawings and assembly guidance are included; on-site engineer supervision is available for complete lines.
Operator training
Manual and video in your language, plus remote guidance via WhatsApp/email during commissioning.
Spare parts support
Long-term supply of wear parts — rollers, dies, blades, screens, nozzles, bearings, reducers, sensors, motors and more.
Warranty & after-sales
12-month machinery warranty and responsive after-sales support from our engineering team.
Why the price varies — and how to get an accurate quote
We do not publish list prices because every fertilizer project is different. This is exactly what makes the difference:
Model & capacity
Larger capacity and heavier construction raise machine cost — but usually lower cost per ton.
Contact material
Carbon steel is standard; 304/316 stainless steel costs more but suits corrosive or food-grade material.
Automation level
Manual, semi-auto and full Siemens PLC control change both price and operating manpower.
Branded components
Standard brands, value package (+8–10%) or premium package (+12–15%) for motors, gearboxes and bearings.
Quantity & packaging
Single machines, complete lines, export packing and spare-parts kits are quoted separately.
Destination & lead time
Freight, port, customs documents and requested delivery time affect the final quotation.
