Why the project happened
A Bolivian customer ordered a double-roller granulation line for dry fertilizer granulation. The line presses powdered or small-particle feed into a compacted sheet that is crushed and screened into uniform granules, avoiding a drying stage.
What the customer faced
These are the specific issues the project was built to solve.
- Dry granulation needed for the customer's material
- Uniform granule size required after crushing and screening
- Line needed to be export-packed for sea freight
Limits we designed around
Real projects are never ideal. These constraints shaped the configuration and delivery plan.
- No drying stage in the route
- Compact layout for container dispatch
Why we configured it this way
YUSHUNXIN supplied the double-roller granulation line from feed hopper through roller press, granule crushing and screening. The dry route avoids a drying stage and produces uniform granules with recycle of oversize and undersize material.
How it was delivered
From requirements confirmation to commissioning - the key nodes of this project.
Requirements confirmation
Confirmed feed material, moisture and target granule size with the Bolivian buyer.
Engineering & configuration
Sized the roller press, crusher and screen around the required output.
Fabrication & assembly
Fabricated and assembled the dry granulation train.
No-load testing & export packing
Tested the route, then export-packed on frames.
Container loading & dispatch
Loaded and dispatched to Bolivia with documents.
Difficult points and how we solved them
Uniform granule size
Combined crushing and screening with recycle of oversize and undersize to stabilize the product.
No drying stage
Selected the double-roller dry route so the material is granulated by pressure alone.
What changed after delivery
Verifiable changes from this project. Where specific figures are confidential, we state the direction and the evidence.
- Double-roller granulation line fabricated and tested
- Dry granulation route delivered without a drying stage
- Export-packed and shipped to Bolivia
Project outcome
Line shipped to Bolivia for dry granulation production.
What similar customers can learn
For dry granulation, the double-roller route is the most direct: pressure forms a compacted sheet, then crushing and screening produce granules with recycle. Confirm feed moisture and granule size first.
