2025-09-30 by organic fertilizer production line

As an important part of agricultural production, its environmental protection measures are of great significance to reduce environmental pollution and improve resource utilization. Here are some effective environmental measures:

Dust control: In the process of mixing, crushing, granulation, etc., dust is collected by sealing equipment and air Collector, and treated by equipment such as Cyclone Dust Collector, bag dust collector or scrubber to reduce dust emission.

Waste Gas treatment: The gas from Gas/Oil Hot Air Stove in the production line needs to be dedusted and desulphurized. Cyclone Dust Collector and water film dedusting technology are adopted to ensure that the exhaust gas meets the emission standards.

Wastewater management: Domestic sewage and production wastewater should be pre-treated through septic tanks, etc., and then appropriate treatment technologies, such as biochemical treatment, physicochemical treatment, etc. should be selected according to the nature of the wastewater to achieve recycling of wastewater or discharge up to standard.

Solid waste treatment: For the solid waste generated in the production process, such as waste packaging bags, dust, etc., should be classified and collected and treated. Recyclable solid waste should be disposed of by the material recovery department, and non-recyclable solid waste should be disposed of safely, such as used as agricultural fertilizer.

Noise control: Through the selection of low noise equipment, plant sound insulation, key parts of the rubber pad and other measures to reduce the noise pollution in the production process.

Odor control: Organic fertilizer may produce odor during the drying process, and the generation and diffusion of odor can be reduced by strengthening ventilation and adopting biological filtration.

Resource recycling: Promote the use of by-products and waste in the Organic Fertilizer Production Line, such as using the hot blast furnace slag generated in the drying process as agricultural fertilizer to realize the recycling of resources.

Enhance environmental awareness: strengthen environmental education and training of employees, improve environmental awareness, and ensure the effective implementation of environmental protection measures.

Environmental monitoring and emergency plan: Regularly monitor the environment around the production line to ensure that pollutant emissions meet standards. At the same time, formulate emergency plans for environmental emergencies and improve the ability to respond to environmental accidents.

Through the implementation of the above environmental protection measures, Organic Fertilizer Production Line can not only effectively reduce the impact on the environment, but also improve the efficiency of resource utilization and promote the sustainabl

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

2025-09-30 by organic fertilizer production line

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.

When choosing an organic fertilizer production line, how to judge its quality and performance?

2025-09-29 by organic fertilizer production line

Organic fertilizer production line is an indispensable facility in modern agricultural production, which directly affects the yield and quality of organic fertilizer. Selecting the right organic fertilizer production line requires comprehensive evaluation from multiple perspectives.

Raw material adaptability: We must first consider the adaptability of the production line to raw materials. 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?

2025-09-29 by organic fertilizer production line

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.

Controlling pellet strength in ring die granulators: Key to fertilizer transportation and storage

2025-09-28 by organic fertilizer production line

Pellet strength is a core performance indicator for fertilizer products. Ring die granulators require multi-step control to ensure pellets can withstand the pressure of transportation and stacking, minimizing breakage and loss.

First, consider the raw material ratio. If the organic matter content in production is too high (over 60%), binders such as clay and bentonite should be added (control the amount to 3%-5%) to increase the viscosity of the raw materials and lay the foundation for pellet strength.

If the proportion of inorganic fertilizer is high, the moisture content of the raw materials should be controlled between 14% and 16% to avoid pellet brittleness caused by too low a moisture content and easy sticking to the ring die granulator due to too high a moisture content.

Selecting the ring die granulator compression ratio is also crucial. The compression ratio (the ratio of the ring die aperture to the effective thickness) should be adjusted according to the fertilizer type. For organic fertilizers with high fiber content, a low compression ratio of 1:8-1:10 is recommended to prevent pellets from being too hard and easily broken. For compound fertilizers, a high compression ratio of 1:12-1:15 is recommended to enhance pellet density. During production, regular spot checks can be performed using a pellet strength tester. If the strength is insufficient, the steam supply to the conditioner can be temporarily increased (by 10%-15%).

In addition, the gap between the roller and the ring die should be controlled within a range of 0.1-0.3mm. A gap too large will cause the raw material to slip, resulting in insufficient pellet density; a gap too small will increase wear and affect pellet consistency. By synergistically controlling these three factors, the compressive strength of fertilizer pellets can be stabilized at above 20N, meeting transportation and storage requirements.
