Our Phosphate Fertilizer Production Line is a state-of-the-art industrial system designed to process raw phosphate ore into high-quality, biologically available fertilizer granules. This line is versatile and can be configured to produce various types of phosphate-based fertilizers, including Single Super Phosphate (SSP), Triple Super Phosphate (TSP), or Enriched Rock Phosphate.
The system integrates crushing, acidulation (chemical reaction), granulation, and drying technologies to ensure the final granules are uniform, hard, and rich in nutrients ($P_2O_5$), meeting international agricultural standards.
Production Process Flow
Step 1: Raw Material Preparation & Milling
Raw phosphate rock is crushed and fed into a Ball Mill or Raymond Mill. The rock is ground into a fine powder to maximize the surface area for the chemical reaction.
* Key Equipment: Jaw Crusher, Ball Mill, Bucket Elevator.
Step 2: Acidification (Chemical Reaction)
The fine phosphate powder is mixed with acid in a specialized Acid Mixer. This triggers a chemical reaction that converts insoluble phosphate into soluble, plant-available nutrients.
* Key Equipment: Vertical Mixer, Acid Storage Tank, Reaction Chamber (Den).
Step 3: Granulation
The reacted material (powder or slurry) is fed into the Granulator. Utilizing rotation and liquid binders, the material aggregates into spherical particles.
* Key Equipment: Rotary Drum Granulator (Recommended for high capacity) or Disc Granulator.
Step 4: Drying & Cooling
Wet granules are passed through a Rotary Dryer to reduce moisture content, ensuring long shelf life and preventing caking. They are then cooled in a Rotary Cooler to harden the structure.
* Key Equipment: Rotary Dryer, Rotary Cooler, Hot Air Furnace.
Step 5: Screening & Packing
The granules are screened to separate oversized and undersized particles (which are recycled back to the granulator). Qualified granules are sent to the Automatic Packing Machine.
Milling Equipment
Raymond Mill: Grinds phosphate rock into fine powder, increasing the surface area for acid reaction.
Granulation Equipment
Granulator: Converts the mixed materials into granular form. There are different types of granulators, such as the disc granulator, rotary drum granulator, and roller granulator.
Drying and Cooling Equipment
Rotary Dryer: Reduces the moisture content of the granulated fertilizer. Cooling Machine: Cools down the fertilizer after drying.
Packaging Equipment
Packing Machine: Packages the finished fertilizer into bags for sale or distribution.
Global Solutions for Agricultural / Mining / Chemical Equipment –
TONGDA Industry Customized Services
Henan Tongda Heavy Industry Science And Technology Co.,Ltd. is dedicated to developing granulation and drying technologies for global clients, serving industries such as chemical, organic, and compound fertilizer manufacturing, as well as mining, forestry, aggregate, and soil remediation. Additionally, we provide segmented process design and solutions for the upgrade of existing production lines in older plants.
Mineral Powder Granulation
The mineral powder granulation process is a process in which mineral powder is transformed into granular products through a series of process steps. This process is commonly used to convert fine powder-like ores or mineral powders into granules for the purpose of storage, transportation, and application.
Sop Production Line
Potassium sulfate is mainly used in tobacco, sugar beets, grapes, watermelons, potatoes, garlic, tea and other potassium-loving and chlorine-not loving crops. Potassium sulfate, as a fertilizer, can improve the quality of crops, such as the combustibility and color of tobacco, improving the sweetness and color of berries and melons more vivid etc.
Municipal Waste Treatment, Sludge Treatment
Urban waste drying refers to the process of drying urban waste to reduce its moisture content and volume. This method is commonly used for wet waste or organic waste to facilitate further processing or disposal.
Organic Fertilizer
Organic fertilizer is a type of fertilizer derived from plants or animals, primarily used to provide plant nutrition while improving the physical, chemical, and biological properties of the soil. There are various types of organic fertilizers, including farmyard manure(chicken manure/cow dung/pig waste), green manure, compost, humus fertilizer, and bio-organic fertilizer.
Organic Inorganic Compound Fertilizer
Organic-inorganic compound fertilizer, also known as mixed organic and inorganic fertilizer, is a type of fertilizer that contains both organic matter and inorganic nutrients. It combines the advantages of organic and inorganic fertilizers, having the soil improvement function of organic fertilizers and the rapid nutrient provision characteristics of inorganic fertilizers.
Composting Fertilizer
Composting is a process of converting organic waste into fertilizer. It involves collecting and piling organic waste, such as food scraps, plant clippings, and animal manure, and utilizing the decomposition action of microorganisms to transform it into compost.
NPK Compound Fertilizer
NPK compound fertilizer is a commonly mixed fertilizer that contains the three main nutrients required for plant growth: nitrogen (N), phosphorus (P), and potassium (K). These elements are crucial for the healthy growth of plants.
BB Fertilizer Production Line
Bulk blending fertilizer making line is also called BB fertilizer production line. BB fertilizer is a compound fertilizer produced by mixing two or more straight fertilizers through mechanical processing. It has the characteristics of low cost and high nutrient concentration.
Slow and Controlled-Release Fertilizer
Slow and controlled-release fertilizer is a new type of fertilizer that regulates nutrient release through physical or chemical methods to meet plant needs while minimizing nutrient loss. Its main advantages include improved fertilizer efficiency, fewer applications, labor savings, and reduced environmental impact.
Chemical Fertilizer (Phosphate / Potash Fertilizer Processing)
China leading manufacturer of chemical fertilizer machines, Tongda Group specializes in the design and supply of high-quality Urea, DAP, MAP, TSP, MKP, DKP and phosphorus fertilizer equipment for compound fertilizer plants, featuring high efficiency, stable operation, long service life, and competitive prices.
Biogas Residue Fermentation and Further Granulation
Biogas residue is the solid residue after anaerobic fermentation in a biogas digester. It is rich in organic matter, nutrients such as nitrogen, phosphorus and potassium, and trace elements. It is a high-quality raw material for the preparation of organic
fertilizers and organic-inorganic compound fertilizers, and is also an important way to utilize agricultural wastes.
Cat Litter Granulation Production Line
Cat litter granulation production line is an automated equipment system specially used to process raw materials into cat litter granules suitable for cats. The production line is mainly composed of raw material processing equipment, mixing equipment, granulator, drying equipment, screening equipment, coating machine, packaging equipment and environmental protection facilities.
Liquid Fertilizer
Liquid fertilizer is a form of fertilizer that can be directly applied or sprayed with water as a carrier. It includes various water-soluble fertilizers such as liquid nitrogen, phosphorus, potassium, and compound liquid fertilizers. The advantages of this type of fertilizer are easy application, high absorption efficiency, and the ability to be directly sprayed on plant leaves or applied through irrigation systems.
