Phosphate Rock Granulation Line
For phosphate rock, phosphate ore powder and partially acidulated phosphate, YUSHUNXIN engineers a low-energy dry-compaction or disc granulation route with milling, classification and hardening for abrasive rock.
Abrasion-hardened contact parts
Fine milling to target fineness
Dry or low-moisture granulation
Closed-loop screening and recycle
Is this solution for you?
Read this first: the solution fits specific customers, scenarios and project stages. If you are not the target, the configuration and quote will not be right.
Suitable for
- Phosphate rock processors
- Phosphate fertilizer producers
- Mining by-product valorization teams
Not suitable / confirm first
- High-moisture chemical granulation (choose the NPK wet route)
- Projects without a defined granule size and strength target
- Single-machine needs - see equipment pages
What customers face before this solution
These are the real operating problems this line is designed to solve - and why they happen.
Typical problems
- Phosphate Rock Granulation Line powder is fine and abrasive, wearing standard parts
- Granules are weak or dusty without the right binder
- Granule size is inconsistent without a screening loop
- Standard fertilizer lines are over- or under-engineered for this mineral
Why they happen
- Equipment selected without an abrasion and flow review
- Binder and fineness not matched to the mineral
- Wrong granulation route for the material moisture
- No screening loop, so fines and oversize are not returned
Why a complete line, not single machines
The right route depends on the mineral's hardness, fineness, moisture and target granule. We match milling, granulation, screening and handling to the mineral so granules are consistent and equipment survives the material.
How the line works
Milling & Sizing
Raymond mill and hammer crusher reduce phosphate rock to the target fineness.
Batching & Conditioning
Weighed dosing blends rock powder with binder and optional additives.
Granulation
Double-roller compaction or disc granulation forms granules at low moisture.
Screening & Recycle
Vibrating or rotary screening returns fines and oversize.
Coating & Packing
Optional anti-dust coating followed by 25-50 kg bagging or FIBC packing.

Why we configure it this way
Equipment is not a list - it is a response to your conditions. This is how your conditions change the configuration:
| When your project is... | We configure... |
|---|---|
| Dry, non-plastic powder | Double-roller compaction - no drying required |
| Moisture-tolerant material | Disc or drum granulation with matched drying |
| High abrasion | Hardened wear plates and replaceable liners |
| Tight size range | Screening loop with fines and oversize return |
Different projects get different configurations
We do not apply one template to every customer. Here are three common scenarios and how the configuration changes.
Phosphate Rock Granulation Line producer
Focus: Consistent granules, low dust
Granulation + screening + bagging
Soil amendment brand
Focus: Stable market-ready granules
Conditioning + granulation + packing
Mining by-product valorization
Focus: Turn powder into saleable granules
Validation-first design with hardened equipment
From inquiry to commissioning
This is the delivery path we follow for every complete line project.
Confirm requirements
Raw materials, formula, capacity, bag size, utilities and site conditions are confirmed in a technical questionnaire.
Process design & layout
We produce a process flow, line layout and foundation drawings sized to your material data.
Quotation with scope
You receive a quotation with an itemized delivery scope - what is included and what is excluded.
Order & fabrication
Fabrication starts with progress updates; long-lead items are ordered first.
Factory testing
Machines are assembled and no-load tested; weighing and control systems are calibrated.
Export packing
Equipment is export-packed with anti-rust treatment and a packing list for customs.
Delivery & installation
Machines ship FOB/CIF/door-to-door; installation is supervised on site or via video guidance.
Commissioning & training
We commission the line, train your operators and stabilize process parameters.
Acceptance & after-sales
Acceptance is based on agreed metrics; spares and remote support continue after handover.
What to prepare before requesting a quote
The better your information, the closer the first quote is to the final one. Prepare these items:
- Material type, fineness, hardness and moisture
- Target granule size, strength and dust tolerance
- Capacity in t/h and operating hours
- Binder availability and cost
- Packing size and destination market
Request a phosphate rock granulation line granulation assessment
Send material type, fineness, hardness, moisture, target granule specs, capacity and binder options for a recommendation.

When this solution does not apply
Honest boundaries make a proposal credible. These conditions must be confirmed before the configuration is valid:
- Granule strength depends on the material-binder combination - validate with samples
- Abrasive material increases wear-part consumption - hardened parts specified
- Moisture-sensitive material may need dry storage outside equipment scope
How we verify the solution works
Performance is checked with measurable indicators, not adjectives. These are the acceptance checks for this type of line:
| Indicator | How it is verified |
|---|---|
| Granule strength and size | Drop/compression test and sieve analysis per shift |
| Fines content | Measure after screening and at the bagger |
| Throughput | Record t/h at design conditions |
