Frequently Asked Questions
The global agricultural sector is rapidly changing due to rising food security demands, population growth, and the push towards more sustainable agricultural practices. Phosphorus fertilizers, especially superphosphate, remain crucial for increasing crop yields and maintaining soil fertility. Among these, triple superphosphate (TSP) stands out as a highly concentrated phosphate fertilizer, providing approximately 46% water-soluble P₂O₅—nearly three times the phosphorus content of single superphosphate (SSP), which contains only 16-20% P₂O₅.
| Property | Specification |
|---|---|
| Phosphorus content (P₂O₅) | 44-48% (typically 46%) |
| Form | Granular (2-4 mm) or powder |
| Solubility | Water-soluble, readily absorbed by plants |
| pH (in water) | 1.5-2.5 (acidic) |
| Hygroscopicity | Moderate (requires anti-caking coating) |
Higher nutrient density = lower shipping cost per unit of phosphorus
Ideal for long-distance transport to Africa, South Asia, and Latin America
Effective for: Grains (wheat, rice, corn), legumes (soybeans, pulses), oilseeds (canola, sunflower), and cash crops (cotton, sugarcane, coffee)
Economical for large farms due to reduced application frequency
For long-distance transportation, TSP is one of the best and most cost-effective options because it contains a very high concentration of nutrients per unit of fertilizer and is very economical to use.
Understanding how triple superphosphate compares to other phosphate fertilizers helps buyers make informed decisions about which product to manufacture or use.
| Fertilizer | P₂O₅ Content | Nitrogen Content | Water Solubility | Typical Use Case |
|---|---|---|---|---|
| TSP | 44-48% | 0% | High | Phosphorus-deficient soils, direct application |
| SSP | 16-20% | 0% | Moderate | Low-cost option, sulfur-deficient soils |
| DAP | 46% | 18% | High | Balanced N+P starter fertilizer |
| MAP | 52% | 11% | High | Acidic soils, precision agriculture |
When TSP is the right choice:
Soil has adequate nitrogen but is phosphorus-deficient
Long-distance shipping cost is a major factor
Farmers want simple, single-nutrient application
Blending with urea or potash for custom NPK mixes
How is triple superphosphate (TSP) made? The TSP production process is a combination of chemical and mechanical processes. Understanding each stage is critical for selecting the right equipment.

The raw materials are phosphate rock (70-75% BPL purity) and phosphoric acid (50-54% P₂O₅ concentration).
Critical quality parameters:
| Parameter | Specification | Why It Matters |
|---|---|---|
| Phosphate rock fineness | 80-85% passing 100 mesh | Finer particles = higher reactivity |
| Phosphate rock moisture | < 3% | Prevents reaction issues |
| Phosphoric acid concentration | 50-54% P₂O₅ | Optimal reaction stoichiometry |
Equipment we supply for this stage:
Jaw crusher / Hammer crusher (primary crushing)
Ball mill / Raymond mill (fine grinding to 100 mesh)
Disc feeder / Belt feeder (controlled feed rate)
Chemical reaction:
Ca₃(PO₄)₂ + 4H₃PO₄ → 3Ca(H₂PO₄)₂ (Phosphate rock) + (Phosphoric acid) → (Calcium dihydrogen phosphate / TSP)
Process details:
In a continuous den reactor or mixer-reactor, phosphoric acid reacts with phosphate rock powder
Reaction temperature: 95-105°C
Retention time: 20-30 minutes
Phosphorus recovery rate: 95-98%
Equipment we supply for this stage:
Phosphoric acid storage tank (lined or stainless steel)
Acid dilution/metering system
Continuous den / mixer-reactor (custom-designed for your capacity)
Purpose: Transform the reactive slurry into uniform, free-flowing granules (2-4 mm).
Equipment we supply for this stage:
Rotary drum granulator – Most common for TSP, 5-50 t/h capacity
Disc (pan) granulator – For smaller plants, 1-10 t/h capacity
Step A: Drying – Rotary drum dryer removes moisture from 12-18% down to 3-5%
Step B: Curing – 4-6 weeks in curing silo to complete reactions and harden granules
Equipment we supply for this stage:
Rotary drum dryer (with temperature controls)
Cyclone dust collector + wet scrubber (for dust and fluoride gas capture)
Curing silo/curing building (designed for proper airflow)
Equipment we supply for this stage:
Vibrating screen / Rotary screener (2-4 mm on-spec separation)
Coating machine (anti-caking or slow-release coating)
Automatic packing scale (600-1,200 bags/hour)
Bag sewing machine
Belt conveyors and bucket elevators (for material transport)
This completes the TSP production process, yielding high-quality triple superphosphate fertilizer with 46% P₂O₅ content.

TSP production involves handling strong acid and generating fluoride-containing gases. Compliance is mandatory in most markets. Maxton integrates environmental equipment into every TSP line we supply.
| Issue | Source | Maxton Solution |
|---|---|---|
| Fluoride gases (HF, SiF₄) | Reactor and dryer | Wet scrubber (venturi + packed tower) |
| Dust | Crushing, grinding, screening | Cyclone dust collector + baghouse filter |
| Acid spills | Acid storage/handling | Secondary containment, acid-resistant flooring |
| Standard | Region | Key Requirements |
|---|---|---|
| EPA 40 CFR 60 | USA | Fluoride emissions <0.45 kg/tonne P₂O₅ |
| World Bank EHS | International | Particulate <50 mg/Nm³, fluoride <5 mg/Nm³ |
Note for plant planners: Environmental controls represent 15-25% of total equipment CAPEX. Skimping on emissions control is unwise—most regions are tightening standards.
Phosphate rock is ground to a fine powder (100 mesh), then reacted with phosphoric acid in a den reactor to form calcium dihydrogen phosphate slurry. The slurry is granulated (2-4 mm), dried, cured for 4-6 weeks, screened, coated, and bagged. Maxton supplies complete TSP production lines for this process.
TSP contains 46% P₂O₅ and 0% nitrogen. DAP contains 46% P₂O₅ and 18% nitrogen. Choose TSP when the soil has adequate nitrogen but is phosphorus-deficient. Choose DAP when both N and P are needed.
TSP plant cost ranges from 150,000forasmall10,000t/year line to over 8,000,000 for a 500,000 t/year industrial line. Contact Maxton for a quote specific to your capacity and location.
Fresh TSP granules are too soft for bagging and shipping. The 4-6 week curing period allows residual chemical reactions to complete, free acid content to decrease from 5-8% to 2-4%, and granules to harden. Maxton can advise on accelerated curing options.
Africa (6-8% annual growth), South Asia (4-5%), and Latin America (3-4%). These regions have phosphorus-deficient soils and growing agricultural production.
Both. We supply individual equipment OR complete turnkey TSP production lines, including design, fabrication, installation, commissioning, and training. Most clients choose turnkey for single-point responsibility.
Rotary drum granulation is most common for TSP production lines above 30,000 t/year. Disc granulation works well for smaller plants (10,000-30,000 t/year). Maxton supplies both and can recommend based on your scale.
