1、 Project positioning and core advantages

　　Scale positioning: With an annual output of 50000 tons, it is an ideal investment scale for prefecture level markets or large agricultural and animal husbandry groups, with significant scale effects, and can effectively cover fertilizer demand within a radius of 100-200 kilometers around.

　　Product matrix: First line productivity, flexible switching according to market demand, producing three categories of products: pure organic fertilizer granules, organic-inorganic compound fertilizer granules (total nutrients ≤ 15%), and bio organic fertilizer granules, with strong market adaptability.

　　Core values:

　　Moderate investment and stable returns: Compared to a 100000 ton production line, the investment threshold is lower, but it can still enjoy the cost advantage brought by large-scale production.

　　High end products with considerable profits: Granular fertilizers have good form, high strength, and are easy to use, with significantly higher market prices and profit margins than powdered fertilizers.

　　Environmental benchmark, policy support: The project itself is a typical resource recycling project that complies with national industrial policies and is easy to obtain various subsidies and support.

　　2、 Detailed explanation of core process flow

　　The 50000 ton pellet production line fully covers the entire process from raw material processing to finished product packaging, and its core technology can be condensed into four major links: "refined composting, uniform batching, skillful granulation, and strict screening".

　　To present this process more intuitively and compactly, the entire process can be summarized as the following vertical flowchart, avoiding overly broad formatting and making it easier to read:

　　Process Stage Analysis:

　　Raw material maturation system (quality cornerstone): After pre mixing feces and straw and other auxiliary materials with a double shaft mixer, they enter a fermentation tank equipped with a chain plate flipping machine for deep aerobic fermentation. Through multiple flips and throws, the temperature can reach 60-80 ℃, completely killing harmful bacteria and producing stable and decomposed basic powdered organic fertilizer. This is the quality starting point for all subsequent products.

　　Powder fertilizer branch line (flexible output): After screening, the powdered fertilizer can be directly made into commercial powder fertilizer for sale through an automatic powder packaging machine, providing fast cash flow for investment.

　　Particle processing system (core value):

　　Precise ingredients: Basic powder fertilizer is accurately proportioned with nutrients such as bentonite, nitrogen, phosphorus, and potassium through a five bin computer ingredient system, achieving product diversification.

　　Homogenization and ultrafine: The prepared material is subjected to secondary mixing and a chain crusher to ensure uniform fineness (up to 0.7mm), which is the key to particle size and strength.

　　Forming and drying: The material is formed in a granulator, smoothed by a rounding machine, and then enters a two-stage series dryer. Adopting the "low-temperature high air flow" process (inlet high temperature, outlet temperature strictly ≤ 65 ℃), efficient dehydration is carried out while protecting the activity of organic matter, and then rapidly cooled and shaped by a cooling machine.

　　Finished product refining system (product guarantee): After cooling, the particles are classified by a screening machine. Qualified products can be coated (for producing biological fertilizers) and screened again to ensure uniform particle size (2-4mm). Finally, they are commercialized by a fully automatic packaging and palletizing line. Unqualified particles are crushed and returned to the granulation process, forming an efficient closed-loop loop to improve raw material utilization and product consistency.

　　3、 List of Key Equipment Configuration

　　The 50000 ton production line pays attention to the balance between performance and investment in equipment selection to ensure high efficiency and reliability.

Key selection points: The core of the pellet line lies in the granulation, drying, and cooling sections. In this plan, both the dryer and the cooler are made of heavy-duty cast steel and equipped with high-temperature resistant induced draft fans, which ensures the long-term stable operation of the equipment. All motors and reducers use national standard products, and the core components are guaranteed for 3 years without human damage.

　　4、 Analysis of Investment Benefits and Operations

　　1. Investment estimation

　　Equipment investment: The total investment for the core equipment of the entire production line (including fermentation, powder fertilizer, granulation, packaging, and environmental protection) is approximately 3.5-5 million yuan.

　　Civil engineering support: including fermentation workshop, production plant, warehouse, and environmental protection facilities, with an investment of about 1.5-2.5 million yuan, depending on the construction standards.

　　Total investment: The comprehensive investment for project initiation usually ranges from 5 to 7.5 million yuan, which belongs to medium-sized industrial investment.

　　2. Economic benefit analysis

　　Production cost: The comprehensive cost of granular fertilizer (including raw materials, energy consumption, labor, depreciation) is about 450-600 yuan/ton.

　　Sales price: The market price of granular organic fertilizers varies by category, ranging from approximately 750-1000 yuan/ton, with higher prices for organic-inorganic compound fertilizers and bio organic fertilizers.

　　Profit and return: Calculated at an annual output of 50000 tons and an average price of 850 yuan/ton, the annual output value can reach 42.5 million yuan. Deducting costs, the annual gross profit is considerable. Under good operating conditions, the static investment payback period is approximately 3-4 years.

　　3. Key to successful operation

　　Raw material guarantee: Establish a stable raw material collection and storage system with surrounding breeding farms and planting bases.

　　Process control: It is particularly important to master core process parameters such as fermentation maturity, granulation moisture, and drying temperature.

　　Market development: Focusing on the characteristics of granular fertilizers, we will focus on developing customers with high requirements for fertilizer quality, such as operating areas and cooperatives.

　　Policy utilization: Actively apply for relevant subsidies for projects such as the resource utilization of livestock and poultry manure and the comprehensive utilization of straw.
