In the composting process, the odor of chicken manure has always been a difficult problem to deal with. Traditional fermentation is not only inefficient, but also causes secondary pollution to the environment. To solve this problem, our company has proposed a new composting fermentation method. Adding fermentation agents to chicken manure and using windrow composting can effectively improve composting efficiency and organic fertilizer quality. Next, I will introduce this chicken manure composting solution to you in detail.   Chicken Manure Composting Process 1. Choose chicken manure material Choose fresh chicken manure and spread it on the cement floor or plastic film. If it is a long-term pile of chicken manure, it is recommended to add some fresh chicken manure, because the chicken manure will ferment naturally after being piled for a long time, but the decomposition is not complete, and this kind of old chicken manure is not easy to heat up. 2. Add ingredients such as a fermentation agent Add fermentation agent: It is recommended that the high-temperature fermentation agent newly produced by our company be added for fermentation. This type of decomposition agent heats up quickly, ferments completely and thoroughly, and has less odor during the fermentation process. Generally, 500 grams of fermentation agent can ferment 1-2 tons of chicken manure. Add straw: Sawdust, wheat, corn, straw, and other straw can be added to chicken manure, and the general length is 1-2 cm. If an organic fertilizer fermentation agent is used for fermentation, the proportion of straw added can be 10%-20%. The main purpose of adding straw is to make the material loose and breathable so that microorganisms can multiply in large numbers and fermentation can proceed better. 3. Add water in moderation: Chicken manure is generally dry. The moisture content of fermented chicken manure is required to be 55%. The criterion is that the chicken manure does not drip when picked up, but water marks can be seen between the fingers. 4. Stacking and fermentation in strips Pile the mixed chicken manure into 1-2 meters (proper stacking in winter is conducive to temperature increase), with a width of 1.5-3 meters, and the length is determined according to the amount of material. Key point 1: No need to cover! In order to prevent water loss, air entry, and temperature increase. Therefore, the composting location should be high, with smooth drainage to avoid rainwater soaking. Pay attention to rain protection in the rainy season, or cover it appropriately when it rains, and remove the film after the rain. It can be covered appropriately in winter. The covering film is dark in color and has good heat absorption, which helps to keep warm. After the temperature rises, the covering needs to be removed. Key point 2: Turn the pile! After the chicken manure is heated, it can effectively kill bacteria, parasite eggs, grass seeds, etc. in the chicken manure. When the temperature in the chicken manure pile reaches 55 degrees, it needs to be turned over and then piled into the original strips. After turning the chicken manure several times, when the internal temperature of the chicken manure does not reach 50 degrees, the fermentation is basically completed. At this time, the chicken manure can be covered and set aside.   Gofine provides efficient composting solutions and sells a variety of composting equipment: Crawler compost turner Chain plate compost turner Wheel compost turner Horizontal fermenter Strand compost turner Tractor-driven compost turner, etc.   If you are interested in our equipment, please feel free to contact me.

What Is a Rotary Drum Granulator? The Rotary Drum Granulator is a key piece of equipment in the compound fertilizer production process, and it is especially popular in NPK fertilizer plants. It is designed for wet granulation, using liquid binders (such as water, steam, or acid solutions) to agglomerate powdery materials into uniform spherical granules.   As a leading fertilizer equipment manufacturer, GOFINE Machine offers high-performance rotary granulators that help clients achieve high output, stable granulation, and excellent product quality.   Working Principle of Rotary Drum Granulator The rotary drum granulation machine works by rotating a slightly inclined cylindrical drum. When the raw materials are fed into the drum: The drum rotates continuously. Powdery materials roll along the inner wall. Liquid binders (steam or water) are sprayed to form adhesive layers. The particles collide, stick, and grow into granules. Granules are discharged from the outlet after reaching the desired size. This wet granulation process provides high granulation efficiency and is especially suitable for large-scale continuous production.   Key Features of Our Rotary Drum Granulator Large capacity: 5–30 tons per hour (customizable) High granulation rate: Up to 90% Uniform granule size: Spherical or oval-shaped (2–6 mm) Corrosion-resistant materials: Carbon steel with anti-corrosion coating or stainless steel Long service life: Precision welding and durable seals Low dust & noise: Eco-friendly design   Applications of Rotary Drum Granulator Rotary drum granulators are widely used in the production of: NPK Compound Fertilizer Urea, ammonium phosphate, potassium chloride, etc. Organic-Inorganic Compound Fertilizer Blends of composted manure and chemical nutrients Bulk Blended Fertilizer (BB Fertilizer) Optional coating after granulation Chemical Granulation For salt, detergent powder, and other industries Suitable Raw Materials Urea Ammonium sulfate Ammonium chloride Ammonium phosphate (MAP, DAP) Potassium sulfate Potassium chloride Organic compost powder Humic acid / Amino acid mixtures   Advantages Compared to Other Granulators Higher production capacity than disc or roller granulators Better suited for continuous NPK fertilizer production More uniform granule shape and size Stronger granules with better moisture resistance Integrated with drying and cooling for streamlined process     Rotary Drum Granulation Process Flow We provide complete fertilizer production line solutions with the rotary drum granulator as the core equipment. The typical process includes: Raw Material Crushing and Mixing—Batching System (Auto/Manual)—Rotary Drum Granulation—Drying (Rotary Dryer)—Cooling (Rotary Cooler)—Screening Machine—Coating (Optional)—Packing Machine This integrated system ensures continuous and automated production with low labor cost and high operational efficiency.   Ready to launch or scale your fertilizer granulation production?

Adding a certain proportion of accelerators during the granulation process of fertilizers can help the raw material powder and particles to agglomerate, improve granulation efficiency, increase the yield rate, and improve the physical properties of particles (strength, surface morphology, anti-disintegration, etc.). In wet granulation, such as drum granulation and stirring granulation, by adding granulation liquid such as water, to the raw material powder particles, the surface of the powder particles is moistened, and solid-liquid cross-linking is formed to agglomerate into particles. On the other hand, in dry granulation, such as briquetting granulation and extrusion granulation, since granulation is completed by the force between molecules, there is no need to add granulation accelerators.     Types of granulation accelerators Granulation accelerators for fertilizers should have the following functions: A certain degree of adhesion High surface tension High solid cross-linking strength after drying. Low cost No harm to crops when mixed with fertilizers Biodegradability of synthetic organic materials   Selection of granulation accelerator Most chemical fertilizers are water-soluble salts. During the granulation process, liquid bridges are formed between powder and particles through dissolution and precipitation in water or granulation liquid, which becomes the driving force for particle agglomeration. Phosphoric acid fertilizers such as monoammonium phosphate (MAP), superphosphate, and triple superphosphate have high solution viscosity. Especially when the pH value is close to neutral, their surface tension and viscosity are further increased, and the adhesion is increased. Granulation accelerators form liquid cross-links between powder particles during the granulation process. The crystal bridges formed after drying have high solid cross-linking strength, which plays a role in promoting granulation. If the proportion of ammonium phosphate (MAP), superphosphate, and triple superphosphate in the fertilizer formula is above 20%, high-strength particles can be granulated with water alone without adding granulation accelerators. In contrast, ammonium sulfate, urea and potassium raw materials such as potassium chloride and potassium sulfate in nitrogen raw materials have relatively small surface tension even in saturated solutions, low solution viscosity and low bonding particle strength. Therefore, in the fertilizer granulation using them as raw materials, adding granulation promoter is effective to improve granulation efficiency and particle physical properties. In particular, urea has low apparent density, large powder porosity and small repose angle, making it difficult to mix evenly with other raw materials. The viscosity and surface tension of saturated solutions are also low, making it difficult to form dense particles. When the proportion of urea in the raw materials exceeds 25%, it is recommended to use granulation promoter. The appropriate granulation promoter is selected by comprehensive consideration of the type of raw materials, mixing ratio and granulation method.   Commonly used granulators: Rotary granulator Using rotary granulation, water or granulation promoter is sprayed in mist during the production process, and the material rotates and rolls along the inside of the granulation container. The particles collide with one another and combine to become larger, and finally grow to the required size. Extrusion granulator During the extrusion granulation process, granulation accelerator and water are added to the raw materials and mixed for granulation. Bentonite and konjac flour are preferably used as granulation accelerators to reduce costs and ensure fertilizer nutrients. Gypsum, sodium humate, waste molasses or lignin sulfonate can also be used as needed. Stirring granulator It adopts the working mode of granulation while stirring. Add granulation liquid, mix and stir through the stirring teeth, and gradually form compact spherical particles.   As the demand for efficient and environmentally friendly fertilizers increases, the research and development of granulation accelerators will continue to develop in the direction of multifunctionality and efficiency. At the same time, we also produce a variety of products such as biological fermentation bacteria and rapid heating composting machines. These products not only improve the production efficiency of fertilizers, but also improve soil quality and promote plant growth.    

How to improve the quality and fermentation speed of composting is the problem you are facing now. Gofine Machine has proposed a new solution for faster and higher-quality composting in organic fertilizer production. Combining microbial fermentation agents with our organic compost turner, this composting treatment method better shortens the composting time, enhances biological activity, and ensures a more efficient and environmentally friendly fertilizer production process.   Why use microbial preparations with a composter? Using microbial fermentation strains (such as Bacillus, Actinomycetes or photosynthetic bacteria) in composting speeds up the decomposition of organic matter and improves the nutritional content of the final product. When used in conjunction with our high-performance compost turners, these microorganisms thrive in a well-ventilated, well-mixed environment, resulting in: Faster compost maturity (15-20 days vs. 30-60 days) Higher cellulose and lignin decomposition rates Deodorizing effects and improved sanitation Increased humus and microbial counts in the compost Better suppression of soil pests and diseases Featured equipment: organic compost turner Gofine offers a full range of composting machinery compatible with microbial inoculants: Through compost turner Suitable for large-scale fermentation in compost troughs Automatic track movement, precise turning Suitable for livestock manure, agricultural waste, and kitchen waste Crawler-type drivable compost turner Suitable for open-air or indoor composting, flexible driving, and no site restrictions Equipped with a microbial fermentation agent throwing device Very suitable for farms and urban solid waste Film covering and turning system Integrates film covering and turning Improve production efficiency Suitable for composting plants with large sites and high output   Gofine sells a variety of organic compost turning equipment and provides you with the best solution.

Whether organic fertilizer can completely replace chemical fertilizer is a complex issue. According to the research of the Chinese Academy of Agricultural Sciences, organic fertilizer cannot completely replace chemical fertilizer, but in some cases, the combination of the two can achieve better results.   Comparison between organic fertilizer and chemical fertilizer 1. Nutrient composition: Organic fertilizer has a wide variety of nutrients and can provide a variety of nutrients required for plant growth, but its nitrogen supply capacity is usually lower than that of chemical fertilizer. Chemical fertilizer provides higher concentrations of nutrients such as nitrogen, phosphorus, and potassium, which can quickly meet the needs of crops. 2. Environmental impact: The use of organic fertilizer has less impact on the environment, can improve soil structure, increase soil organic matter content, and reduce soil acidification and other problems. Excessive use of chemical fertilizers may lead to environmental problems such as soil acidification and water pollution. 3. Yield effect: Studies have shown that when organic fertilizer is used alone, the effect of increasing grain production is weak. For example, it takes 12 to 15 years for winter wheat to reach the same level of increase in production as chemical fertilizer, while it takes 3 to 5 years for corn. However, when organic fertilizer and chemical fertilizer are applied in a 50% ratio, equivalent or higher grain yields can be obtained while reducing environmental impact by more than 30%.     Organic fertilizer mixed with fertilizer granules There are many advantages to mixing organic fertilizer and chemical fertilizer, including: 1. Complementary effect: Organic fertilizer can improve soil structure and increase the organic matter content of soil, while chemical fertilizer provides high concentration of nutrients, which can quickly meet the growth needs of plants. 2. Reduce the side effects of chemical fertilizer: The addition of organic fertilizer can reduce the negative impact of chemical fertilizer on soil, such as salinization and soil compaction. 3. Promote microbial activity: The microorganisms in organic fertilizer can promote nutrient circulation in soil and help plants absorb nutrients better.   Organic fertilizer granulator Organic fertilizer granulator, also known as organic fertilizer pellet machine, is specially used to process fermented organic materials (such as livestock and poultry manure, crop residues, etc.) into pellets. Its main features include: No need for drying and crushing: The equipment can directly granulate the fermented raw materials, saving the drying and crushing steps, thereby reducing production costs and energy consumption. High-efficiency granulation: Commonly used organic fertilizer granulators include extrusion granulators, disc granulators and drum granulators, which can produce spherical or columnar pellets with a high granulation rate [1]. Environmental protection: The use of organic fertilizer granulators helps reduce the discharge of agricultural waste and promote the recycling of resources.   Fertilizer granulator machine Fertilizer granulator is mainly used to process fertilizer raw materials (such as nitrogen fertilizer, phosphate fertilizer, potash fertilizer, etc.) into granules. Its features include: Efficient production: Fertilizer granulator can quickly convert raw materials into granules, suitable for large-scale production to meet market demand. Multiple granulation methods: Fertilizer granulator usually adopts wet or dry granulation process, which can be adjusted according to different raw materials and product requirements. Particle uniformity: The equipment can ensure that the produced granules are uniform and easy to apply and store.   Blended fertilizer (BB fertilizer) granulator Blended fertilizer granulator is a highly efficient equipment specially used for producing organic fertilizer, chemical fertilizer and blended fertilizer. It adopts forward and reverse operation and special inner spiral mechanism to ensure uniform mixing and granulation of materials. It has the advantages of compact structure and small footprint, and is suitable for production lines of various sizes. The equipment has high production capacity, simple operation and is suitable for processing a variety of fertilizer granules.     Feel free to contact me! I will customize the best granulation solution for you. Looking forward to our cooperation!
