Ending Import Dependency——Longguang SSP Production Line Reduces Costs by 30% for Ethiopian Client
For fertilizer producers in Africa, the biggest challenge is rarely demand – it is reliance on imported raw materials. A mid-sized Ethiopian plant was trapped by imported phosphate rock, suffering repeated shutdowns due to foreign exchange shortages and logistics delays. After installing Longguang’s Single Superphosphate (SSP) Production Line, they replaced 80% of imported rock with local phosphate, cut raw material costs by 30%, and doubled their annual output.
The Problem: Sitting on Phosphate, But Forced to Import
Ethiopia has abundant medium-low grade phosphate reserves (18–24% P₂O₅), yet most local equipment cannot process it effectively. The client’s old production line had three critical weaknesses:
Incomplete reaction: The acidulation conversion rate was only 75%, leaving much of the phosphorus locked in waste. Finished product often fell below the national standard of 12% available P₂O₅.
Import dependency: They had to import high-grade rock (≥30% P₂O₅) from Morocco or China at a landed cost of $180 per ton.
Foreign exchange bottlenecks: Frequent FX shortages delayed letters of credit by 2–3 months, causing three to four production stoppages every year.
“We were standing on phosphate rock, but we had to pay others for theirs,” the plant’s production manager recalled.
The Longguang Solution: An SSP Line Built for MediumLow Grade Rock
After testing local ore samples on site, Longguang designed a customized SSP Production Line with one goal: make local 21% P₂O₅ rock perform like imported high-grade ore.
The main equipment includes:
Jaw Crusher – Coarsely crushes large pieces of local phosphate rock to a consistent size for downstream processing.
Vertical Multiple Paddle Mixer – Uses multiple paddles to forcibly mix phosphate powder with sulfuric acid, ensuring microscopic-evel contact and significantly improving reaction efficiency.
Rotary Chemical Synthesis Chamber – The core reaction unit. Its slow rotation extends material residence time, allowing more complete acidulation and a major boost in conversion rate.
Fluorine Absorbing Unit – Captures fluorine-containing gases, recovers fluorosilicic acid as a valuable byproduct, and meets environmental emission standards.
An automatic control system adjusts acid ratio, temperature, and mixing speed in real time for batch-to-batch consistency.
Technical Highlights: Conversion Rate from 75% to 88%
Longguang‘s SSP line delivers several key improvements over conventional processes:
Most importantly, the line offers flexible raw material blending – local rock and imported rock can be mixed in any ratio. The client can adjust based on FX availability and inventory.
The Results: 30% Lower Cost, Double Output, Full Import Independence
Six months after commissioning, the client reported the following results:
Raw material cost: Dropped from $180 per ton of SSP to $126 per ton – a 30% reduction (using mainly local 21% rock with only 20% imported rock as a “starter”).
Output increase: No more import-driven shutdowns. Annual production rose steadily from 15,000 tons to 30,000 tons – doubled.
Product quality: Available P₂O₅ content stabilized at 16%, well above Ethiopia’s national standard of 12%, building strong trust among local farmers.
Byproduct revenue: Fluorosilicic acid recovered by the Fluorine Absorbing Unit sold to local water treatment plants, generating an extra $40,000 per year.
Even during Ethiopia’s tightest foreign exchange quarters, the plant kept running continuously – no more waiting for letters of credit.
Client Testimonial
“We were sitting on phosphate rock but buying from abroad. Longguang’s SSP line taught us how to turn stone into gold. Now our fertilizer is 15% cheaper than imports, but its quality beats any international brand.”
— Tekle Berhan, Production Director, Ethiopian Fertilizer Plant
Conclusion: A Proven Path to Ending Import Dependency
For countries in Africa, South America, or Central Asia that have medium-low grade phosphate reserves but lack processing know-how, Longguang’s SSP Production Line – featuring the Jaw Crusher, Vertical Multiple Paddle Mixer, Rotary Chemical Synthesis Chamber, and Fluorine Absorbing Unit – is a proven way to end import dependency. It turns local rocks into qualified fertilizer and gives manufacturers true supply chain security.
