Written by fertilizer production line on October 10th, 2025. Leave a comment

With increasingly stringent environmental protection policies, environmental retrofitting of organic fertilizer production lines has become an industry imperative, focusing on the treatment of “three wastes” and compliance upgrades.

For waste gas treatment, organic fertilizer production lines must be equipped with sealed fermentation chambers and ammonia collection systems. Biofilter technology is used to control ammonia concentrations generated during the fermentation process to within standards. Some areas also require VOC monitoring equipment to ensure real-time upload of emission data.

For wastewater treatment, production lines must establish a recycling system to sediment and filter wash water and condensate before reusing them for raw material moisture conditioning, achieving zero wastewater discharge.

For solid waste treatment, optimized screening processes are employed to re-crush fermentation residues before mixing them back into fermentation, achieving full solid waste utilization.

Furthermore, the environmental impact assessment process imposes stricter requirements on production line site selection and capacity planning, such as requiring them to be at least 500 meters away from residential areas and designing production capacity to match the regional environmental carrying capacity. Although these transformations increase initial investment (usually the transformation cost of a single production line accounts for about 15%-20% of the total investment), the energy consumption of the organic fertilizer production line can be reduced by 12%-18% after the transformation.

Organic fertilizer production line was used to process chicken manure

Written by fertilizer production line on October 10th, 2025. Leave a comment

Organic fertilizer is favored by agricultural production because of its ability to improve soil structure, increase organic matter content and enhance soil fertility. Among them, chicken manure as a high-quality organic fertilizer raw material, its processing has attracted much attention. This article will explore how to efficiently process organic manure from chicken manure through organic fertilizer production lines and ensure its quality and safety.

1. Raw material preparation and pretreatment

Chicken manure requires strict pretreatment before processing to eliminate pathogens and weed seeds in it. This usually involves composting treatment, which breaks down organic matter through the action of microorganisms while releasing heat to achieve bactericidal and deodorizing effects. The pre-treated chicken manure can enter the organic fertilizer production line for further processing.

2. Drying and sterilization of chicken manure

One of the key steps in an organic fertilizer production line is drying. By using professional drying equipment, such as Rotary Dryer Machine, the moisture content of chicken manure can be effectively reduced, its stability can be increased, and the subsequent granulation process can be facilitated. In addition, the high temperature during the drying process can further sterilize, ensuring the safe use of organic fertilizers.

3. Ingredient mix and nutrition balance

In the organic fertilizer production line, chicken manure is usually mixed with other auxiliary materials such as straw, shells, etc., to adjust the carbon nitrogen ratio and ensure the nutrient balance of organic fertilizer. This step is done through the Bulk Blending Fertilizer Production Line, ensuring that the final product can meet the needs of the different crops.

4. Granulation molding

The mixed raw materials will enter the granulator, such as the Fertilizer Granules Compaction Machine, for molding processing. This step forms the raw material into a uniform granular form that is easy to apply and store. Granulation can not only improve the appearance of organic fertilizer, but also improve its dispersion and absorption rate in the soil.

5. Screening and packaging

The organic fertilizer after granulation needs to be screened by Rotary Screening Machine to ensure uniform particle size and meet product quality standards. The qualified product is then packaged to become the final chicken manure organic fertilizer product.

6. Quality control

In the whole process of organic fertilizer production line, quality control is an indispensable link. By regularly testing the number and activity of microorganisms in organic fertilizers, the effectiveness and safety of the product can be assessed. For example, the application of bio-organic fertilizer can increase the capacity of soil microorganisms to utilize carbon sources, improve microbial nutrient conditions, maintain high microbial activity, and increase soil microbial diversity.

Through the above steps, the organic fertilizer production line can efficiently convert chicken manure into high-quality organic fertilizer products. This processing method not only improves the efficiency of resource utilization, but also helps to improve the quality and safety of agricultural products, and also contributes to the sustainable development of agriculture. With the advancement of technology and the growth of market demand, organic fertilizer production lines will continue to play an important role in modern agricultural production.

How can you use new type organic fertilizer granulators more efficiently and save energy and materials?

Written by fertilizer production line on October 9th, 2025. Leave a comment

Many organic fertilizer plants are concerned about costs. However, when using new type organic fertilizer granulators, paying attention to two small details can significantly save energy and materials.

To save energy, most new type organic fertilizer granulators are equipped with variable-frequency motors. Avoid running them at maximum speed all the time. For example, when initially feeding, use a low speed of 15 rpm. Once the raw materials have stabilized in the granulation chamber, gradually increase the speed to 20-25 rpm. This prevents the motor from exerting sudden force, saving 10%-15% of energy per hour. Additionally, avoid idling the machine. Do not start the machine until the raw materials are ready. The energy wasted in idling for one hour is enough to generate granules for 20 minutes.

To save materials, the key is to reduce waste. New type organic fertilizer granulators have a return device. Instead of discarding the crushed granules, they are directly returned to the granulation chamber through the return port, where they are mixed with new raw materials and granulated again. This can reduce the waste rate from 10% to less than 3%. Also, do not mix impurities such as stones and iron wire into the raw materials. Impurities will wear out machine parts and crush good particles. Use a sieve before feeding each time to avoid a lot of material waste.

When using windrow compost turning machines in different seasons, pay attention to key details

Written by fertilizer production line on September 30th, 2025. Leave a comment

A windrow compost turning machine isn’t a one-size-fits-all model. Adjusting details according to the season will ensure smooth fermentation of your organic fertilizer.

Spring’s high humidity and fluctuating temperatures can easily lead to a musty odor in the compost. When using a compost turner, increase the frequency of turning the compost. Instead of turning every two days, turn every 1.5 days in spring. Loosen the compost to allow moisture to escape, and monitor the temperature. If the temperature is below 50°C, slow the compost turner’s speed to allow for a more thorough turning, allowing microbial activity to raise the temperature.

Summer temperatures are high, and the compost easily overheats (over 70°C kills beneficial bacteria). Reduce the depth of each turning to avoid bringing all the hot material below to the surface. Turn the compost once a day. Sprinkle a thin layer of soil on the surface after each turning to provide shade and reduce temperatures while preventing rapid evaporation.

Autumn is dry, and the pile is prone to dehydration and cracking. Use a windrow compost turning machine with an atomizer, spraying small amounts of water as you turn to maintain a humidity level of 50%-60%. Slow the turning speed to allow the water and raw materials to mix thoroughly and avoid patches of dryness or wetness.

Winter is cold, and the pile struggles to heat up. Reduce turning frequency to once every three days, avoiding frequent turning to disperse heat. When turning, pile the pile higher (1.2-1.5 meters). Try turning the cold material in the center with the windrow compost turning machine, covering the hot material on the outside to help retain heat and ferment.

High-quality Organic Fertilizer Production Linecan adapt to a variety of raw materials, including livestock manure, straw, food industry by-products, etc. The diversity of raw materials directly affects the nutritional value and production cost of organic fertilizers.

Production capacity: The production capacity of the production line should match the scale and needs of the farm. For example, for large-scale farms, you may need to choose a production line that produces hundreds of tons per day, while for small-scale farms, you may need to choose a production line that produces tens of tons per day.

Equipment composition: Organic fertilizer production line usually includes grinding, mixing, granulation, drying, screening and packaging and other links. The equipment performance of each link will affect the quality of the final product. For example, the Disc Granulator is able to produce uniform particles, which helps to improve fertilization efficiency.

Environmental performance: In the production process, the production line should meet the environmental requirements and reduce the impact on the environment. This includes emission reduction, noise control, waste disposal and more.

Degree of automation: modern organic fertilizer production lines are increasingly inclined to automation, which can reduce labor costs and improve production efficiency. Production lines with a high degree of automation can more accurately control various parameters in the production process.

Energy consumption: The energy consumption of the production line is also an important indicator to measure its performance. Energy efficient production lines can reduce production costs while also meeting the requirements of sustainable development.

After-sales service: It is important to choose a production line with good after-sales service. This includes services such as installation, commissioning, maintenance and upgrading of equipment.

Return on investment: Finally, you need to consider the return on investment of the production line. This includes equipment acquisition costs, operating costs and maintenance costs. A high-quality production line should be able to recover the investment cost in a relatively short time.

Through the comprehensive evaluation of the above aspects, the quality and performance of the organic fertilizer production line can be judged, so as to make a reasonable choice.

How to adapt a BB fertilizer blender to different raw material characteristics?

Written by fertilizer production line on September 29th, 2025. Leave a comment

BB fertilizer raw materials come in a variety of forms (granular, powdered, and fiber-containing). BB fertilizer blenders require targeted adjustments to accommodate these different raw material characteristics and avoid mixing problems.

For pure granular raw materials (such as urea and diammonium phosphate granules), which have relatively small density differences but are prone to rolling and stratification, the BB fertilizer blender should be equipped with guide plates within the mixer drum to guide the raw materials into upward and downward circulation and control the feed order. Adding the denser diammonium phosphate first, followed by the lighter urea, can reduce initial stratification. The speed can be appropriately reduced in the later stages of mixing to prevent excessive collisions between particles that could lead to breakage.

If the raw materials contain powdered ingredients (such as potassium chloride powder or trace element powder), a dustproof seal should be installed at the BB fertilizer blender feed port to prevent dust from escaping. Additionally, an atomizing humidifier (control the humidity to ≤15%) should be installed within the mixer drum. A small amount of humidification can enhance adhesion between the powdered raw materials and the granules, preventing dust from becoming suspended.

When the raw materials contain fiber organic fertilizer (such as fermented straw powder), it is necessary to use a paddle with a shearing function to prevent the fibers from entangled and clumping. At the same time, the fiber raw materials should be crushed to less than 3mm in advance to reduce mixing resistance. During the mixing process, the machine can be stopped and observed every 3 minutes. If fiber clumps are found, the paddle angle needs to be adjusted to enhance the shearing and dispersion effect to ensure that the fibers and granular fertilizer are fully integrated.
