1、 Project positioning and product strategy: diversification and high value

　　Market positioning: With a production capacity of 100000 tons of granular organic fertilizer, it is positioned to serve the national or regional market, meeting the demand for standardized and high-quality fertilizers from large farms, agricultural cooperatives, and high-end economic crop planting areas.

　　Core raw materials: Using livestock and poultry manure (such as cow, sheep, pig, chicken manure, etc.), municipal sludge, biogas residue, and crop straw as core raw materials to achieve complete resource utilization of waste.

　　Product matrix (frontline productivity): With the strong formula and processing capabilities of this production line, it can flexibly produce three categories of high-value fertilizers, achieving full market coverage and maximizing profits:

　　Pure organic fertilizer granules: high-quality commercial organic fertilizer that meets national standards.

　　Organic inorganic compound fertilizer granules: add inorganic nutrients such as nitrogen, phosphorus, and potassium (total nutrients ≤ 15%) to achieve a combination of quick acting and long-term effects.

　　Bio organic fertilizer granules: Adding functional bacterial strains during the granule coating stage has the biological effects of improving soil, disease resistance, and promoting growth.

　　2、 Detailed explanation of core process flow: from waste to high-quality granules

　　The production of granular fertilizers is a comprehensive application of physical, chemical, and biological technologies, and the process is much more complex than that of powdered fertilizers. Its core lies in "precise fermentation, deep processing, and strict granulation", and the entire process can be divided into four major system modules.

　　To clearly demonstrate the complete transformation path of materials from their original state to high-quality particles, the following overview flowchart is compiled:

　　The following is a detailed analysis of each core system:

　　1. Raw material pretreatment and efficient fermentation system

　　This is the cornerstone of ensuring product safety and quality.

　　Precise pre mixing: Feces and crushed straw and other auxiliary materials are scientifically mixed through an independent silo and a double axis mixer, adjusting the initial carbon nitrogen ratio and moisture content.

　　Deep fermentation: A fully automatic chain plate flipping machine is used for aerobic fermentation in the fermentation tank. Through PLC control, timed and uniform flipping can be achieved to ensure that materials are fully decomposed and pathogens are killed at high temperatures of 60-80 ℃. This process can effectively reduce moisture content.

　　Powder preparation: After being crushed by a two-stage crusher, the decomposed clinker is sieved through a drum screen to remove impurities and obtain a uniform powdered organic fertilizer. It can be directly packaged as powder fertilizer or enter the granulation process.

　　2. Ingredient mixing and fine conditioning system

　　This is the "formula focus" for achieving product diversification.

　　Computer batching: Basic powder fertilizer, bentonite (binder), humic acid, and inorganic nutrients such as nitrogen, phosphorus, and potassium are accurately measured and proportioned using a multi bin computer batching scale.

　　Ultra fine mixing: After the prepared materials are vigorously mixed by a double shaft mixer, they are finely ground by a vertical crusher to ensure that all materials have a fineness of less than 0.7mm, which is a key prerequisite for forming uniform and solid particles in the future.

　　3. Granulation, drying, and cooling shaping system

　　This is the core physical processing step of particle molding.

　　Forming and polishing: Micro powder materials are agglomerated into particles by adding a small amount of water in a granulator (disc or drum), and then enter a polishing and shaping machine to make the particle surface smooth and the shape regular.

　　Low temperature drying: Wet particles enter a two-stage series dryer and use the "low temperature high air flow" process (inlet high temperature, outlet temperature strictly ≤ 65 ℃) to gradually reduce the moisture content of the particles from about 30% to 20%, effectively protecting the organic matter and active substances in the fertilizer.

　　Cooling and shaping: After drying, the hot particles come into full contact with a large amount of cold air in the rotary cooling machine, rapidly cooling down. This process is not only convenient for storage, but also can condense surface moisture, significantly improving particle strength and hardness, and ultimately stabilizing the moisture content of the finished product at around 15%.

　　4. Finished product finishing and packaging system

　　This is the final check to ensure the uniformity of product appearance and quality.

　　Fine screening and return circulation: After cooling, the particles are classified by a drum screening machine. The particles that meet the specifications (usually 2-4mm) enter the next process, while the particles that are too large or too small are automatically sorted and crushed before returning to the granulator for re granulation, forming a closed-loop circulation and achieving "zero waste" of raw materials.

　　Coating and secondary screening (optional): Qualified particles can enter the coating machine, spray functional bacterial solution to produce bio organic fertilizer, or undergo anti caking treatment. Afterwards, perform a secondary screening to ensure uniform particle size and enhance the product image.

　　Intelligent packaging: The finished particles are accurately measured, bagged, sealed, and palletized by a fully automatic packaging and palletizing production line, with unmanned operation throughout the entire process, greatly improving terminal efficiency.

　　3、 Key equipment configuration list and selection analysis

　　The 100000 ton pellet production line is an integrated equipment for heavy, complex, and continuous operations. Its equipment investment and complexity are much higher than those of powder fertilizer production lines of the same scale.

Selection warning: Drying machines, cooling machines, and granulators in particle production lines are large-scale rotary equipment, and their main material thickness, casting strength, and bearing configuration directly determine the equipment's lifespan and operational stability. It is necessary to specify the use of heavy-duty cast steel parts (rolling rings, gears, etc.) and high-temperature resistant fans. The motor and reducer must be national standard products, and key equipment must be provided with non-human damage warranty.

　　4、 In depth analysis of project investment and benefits

　　1. Investment scale estimation

　　The pellet production line has seen a significant increase in equipment investment due to the addition of numerous processes such as granulation, drying, cooling, coating, and complex screening.

　　Total equipment investment: The investment in core production line equipment (excluding fermentation part) is about 4-6 million yuan. The investment for the entire production line, including the complete fermentation and pretreatment system, is approximately 7-10 million yuan.

　　Civil engineering and supporting facilities: require larger factory buildings (including fermentation tanks, production workshops, and finished product warehouses), more complex energy sources (natural gas or steam heating), and environmental protection facilities, with an investment of approximately 3-5 million yuan.

　　Total investment scale: A well-equipped 100000 ton granular organic fertilizer project, typically with a total investment of 10-15 million yuan or more, belongs to a heavy asset investment project.

　　2. Economic benefit model

　　Production cost: Due to the complex process and high energy consumption, the comprehensive cost of granular fertilizer is about 500-700 yuan/ton.

　　Sales price: The added value of granular organic fertilizers (especially organic-inorganic compound fertilizers and bio organic fertilizers) is high, and the market price is usually between 800-1200 yuan/ton, or even higher.

　　Profit and return: The annual output value can reach 80-120 million yuan, and the gross profit margin is significant. Although the investment is significant, high-quality granular fertilizers have high profit margins and strong market competitiveness, with an expected static investment payback period of 4-6 years. You can also actively apply for various environmental protection and resource utilization policy subsidies.

　　3. Operational core and risk management

　　Key to success:

　　Proficient in technology: Fine control of process parameters such as drying temperature, material fineness, and return ratio is required, requiring a professional production technology team.

　　Quality management: Establish a comprehensive testing system from raw materials, semi-finished products to finished products to ensure that products meet national standards.

　　Brand and Channel: High value products need to be matched with strong brand building and sales networks.

　　Main risks:

　　Technical risk: Improper process control can easily lead to low particle formation rate, poor particle strength, drying agglomeration, and other problems.

　　Market risk: We need to face competition from traditional fertilizers and other brands of organic fertilizers.

　　Financial risk: Large investment amount, high requirements for the financial chain.
