Fulvic Acid Fertilizer Manufacturing Plant: Feasibility Analysis

Fulvic acid, a substance derived from the essence of natural humus, has become an indispensable type of fertilizer for modern and efficient agriculture with its powerful soil improvement ability, promotion of plant nutrient uptake and enhancement of resistance.

With the increasing global attention to green agriculture and soil health, the market demand for fulvic acid fertilizer is surging, and investment in building a professional fulvic acid fertilizer manufacturing plant is ushering in a golden opportunity. The key to success lies in the precise control of core raw materials, scientific technology, and efficient and reliable production equipment.

I. Fulvic Acid Fertilizer Manufacturing Plant Core Raw Materials

The quality of fulvic acid comes from the selection of raw materials. We have developed fulvic acid fertilizer manufacturing plant solution after continuous experiments and improvements:

Carbon-rich organic matter:

• Lignite/weathered coal: the most common and cost-effective raw material. It contains humic acids (mainly brown and black humic acids) that need to be further activated and degraded. Our plants are optimized for their physical characteristics (e.g. high viscosity, potential impurities).
• Peat: Contains a high proportion of native humic acids (including xanthic acid) and is often of better quality, but is more costly and limited in availability. Equipment design takes into account its milder treatment needs.
• Lignin and its derivatives: By-products of the paper industry (e.g. lignosulfonates) are a renewable resource with great potential. Our process equipment effectively converts them into highly reactive, small molecule xanthic acid in a targeted manner.
• Agricultural waste: Straw, rice husk, etc. can also be used as a supplementary source of raw materials after appropriate pretreatment (e.g. fermentation, pyrolysis), reflecting the value of circular economy.

II. Fulvic Acid Fertilizer Manufacturing Plant: from waste to fulvic acid fertilizer

The fulvic acid fertilizer manufacturing plant we provide is a complete production system that can guarantee your project to be put into production quickly.

Pre-treatment of raw materials:

1. Crushing & Grinding: Using a jaw crusher or Raymond mill, lumpy raw materials (e.g. lignite) are crushed to the target fineness (typically 80-200 mesh), which significantly increases the reaction contact area and improves subsequent extraction and oxidation efficiency.
2. Screening: Vibrating screener removes impurities and large particles to ensure homogeneity of the feedstock.

Alkaline solubilization extraction:

1. The crushed raw materials are mixed with a certain concentration of alkali solution (such as KOH solution) in a strong alkali corrosion-resistant reaction vessel.
2. The vessel is equipped with a highly efficient variable frequency stirrer (anchor, paddle or turbine) to ensure adequate mixing of solids and liquids; the jacket or coil precisely controls the temperature (usually at 60-90°C) to optimize the extraction efficiency. The extraction time varies depending on the raw material and the efficiency of the equipment.

Solid-liquid separation (primary separation):

1. The extracted mixture is separated through a filter.
2. The filtrate (containing mainly humates) goes to the next process. The filtrate (containing mainly insoluble impurities and ash) can be considered for resource utilization or safe disposal. Our separation equipment is highly efficient, filtrate is clarified, filter cake is dry and loss of active ingredients is reduced.

Oxidation/degradation (fulvic acid fertilizer manufacturing plant core process):

1. This step is the key to fulvic acid fertilizer manufacturing plant. Oxidizing agents (e.g. H₂O₂, K₂S₂O₈) are precisely and controllably added to the humate solution in a special pressure and corrosion resistant oxidation reactor.

The core advantages of the Fulvic Acid Fertilizer Manufacturing Plant:

1. Precise Temperature Control System: Maintains optimal reaction temperature (often 60-80°C, higher for specific processes) to ensure stable and efficient reaction, avoiding over-oxidation or side reactions.
2. Adjustable homogeneous mixing: Specially designed mixing systems (e.g. multi-layer turbine, high shear) combined with optional gas distributors (if O₃ or air is used) greatly enhance the gas-liquid/liquid-solid mass transfer rate, significantly reducing the reaction time and increasing the conversion rate of fulvic acid.
3. Safety and reliability: Equipped with pressure/temperature sensors, safety valves, and an automatic release system to ensure absolute production safety under strong oxidizing environments.
4. Precise metering and dosing: automated metering pumps precisely control the amount and speed of oxidizer and catalyst addition to ensure the consistency of product quality and process repeatability.

Acid precipitation purification and secondary separation:

1. The oxidized solution is adjusted to acidic pH (usually pH 1-2) with acid (e.g. HCl) to precipitate fulvic acid.
2. High purity wet fulvic acid filter cake is obtained again by high efficiency solid-liquid separation equipment (e.g., high-speed tube centrifuge or precision filter press). The separated acidic mother liquor can be partially reused or neutralized.

Drying and granulation (finished product sizing):

1. Granulation: Using organic fertilizer granulator, the wet fulvic acid is granulated and shaped through the high-speed rotary shear of the pin.
2. Belt drying/drum drying (granule/flake products): After the wet filter cake is shaped by granulator, it is dried by hot air penetration in multi-layer mesh belt dryer or rotary drum dryer to get granule products.
3. Packing: The dried fulvic acid granules are packed by automatic quantitative packaging machine.
