The Secrets of Bio-Organic Fertilizer Production Lines

by organic fertilizer production line

The bio-organic fertilizer production line is the core vehicle for transforming agricultural waste into high-quality fertilizer. Its production process requires scientific proportioning and precise processing to ensure the fertilizer is both nutritious and active.

The first step in production is raw material pretreatment. Workers transport raw materials such as livestock and poultry manure, straw, and mushroom residue to the workshop, where they are sorted to remove impurities. A crusher then pulverizes the straw and other coarse fiber materials to 2-5 mm. An automatic batching system then automatically mixes the various raw materials according to the optimal carbon-nitrogen ratio of 30:1 and adds composting agents, laying the foundation for subsequent fermentation.

The second step is the high-temperature aerobic fermentation stage. The mixed raw materials are fed into a fermentation tank or vat, where the fermentation system continuously controls temperature, humidity, and oxygen content. The temperature initially rises to above 55°C to kill insect eggs and pathogens; in the middle, it is maintained at 60-70°C to promote microbial decomposition of organic matter; and in the later stages, the temperature gradually decreases to form stable humus. The entire process takes approximately 7-15 days, during which time a compost turning machine turns the fertilizer every 2-3 days to ensure even fermentation.

After fermentation is complete, the material enters the advanced processing stage. A drum screener separates the uncomposted coarse material (which returns to the fermentation stage). Qualified material is then fed into a granulator (such as a rotary drum granulator or a new type organic fertilizer granulator). Depending on market demand, it can be produced in various forms, such as granules or powders. The granular fertilizer needs to go through a drum fertilizer dryer to reduce the moisture content to below 15%, and then pass through a drum cooler to cool it to room temperature to prevent clumping.

Finally, the finished product is processed and tested. After cooling, the fertilizer is coated with a probiotic agent in a film coating machine to improve its effectiveness and stability. It is then weighed and packaged. Quality inspection departments will sample and test the fertilizer for indicators such as organic matter content and effective viable bacterial count. Only products that meet national standards are labeled and shipped to farmland, providing green energy for crop growth.

Screening in an Organic Fertilizer Production Line

by organic fertilizer production line

In the entire organic fertilizer production process, the screening process acts as a sophisticated “quality filter,” directly determining the particle uniformity and impurity content of the final product. It is the core link between fermentation and finished product packaging. Neglecting meticulous control of the screening process can lead to reduced product quality due to residual impurities or uneven particle size, even with the most advanced fermentation processes, impacting market competitiveness.

Currently, mainstream organic fertilizer production lines mostly utilize a combination of “vibration screening + drum screening.” The vibrating screener machine‘s high-frequency vibrations quickly separate large impurities (such as uncomposted straw and gravel) from the material. The screen’s aperture can be flexibly adjusted to product requirements, typically selecting a 10-20 mesh size to meet common organic fertilizer standards. The drum screener machine, on the other hand, uses a slowly rotating cylindrical screen drum to perform a secondary classification of fine particles, effectively removing powdery materials and ensuring a final particle size deviation within ±2mm. The synergistic operation of these two devices can increase material screening efficiency to over 95%, significantly reducing the risk of blockage in the subsequent packaging process.

Operational control during the screening process is equally critical. Screen wear must be regularly inspected, and if mesh deformation exceeds 5%, it must be replaced promptly to avoid missed screens. Furthermore, equipment parameters must be dynamically adjusted based on the moisture content of the material. If the moisture content of the fermented material exceeds 30%, the vibration frequency or drum speed must be appropriately reduced to prevent the material from sticking to the screen and affecting screening efficiency. By establishing a management system that includes “two-hourly screen inspections and real-time moisture content monitoring,” one organic fertilizer manufacturer increased its product qualification rate from 88% to 99.2%, reducing annual reject losses by over 120 tons.

As the organic fertilizer industry’s demand for product quality increases, screening technology is evolving towards intelligent technology. Some advanced production lines have incorporated IoT monitoring systems, using sensors to collect real-time data such as screening output and impurity separation rate, enabling unmanned, precise screening. This technological innovation not only reduces labor costs but also further ensures the stability of screening accuracy, laying a solid foundation for organic fertilizer products to enter the high-end market.

Common Problems and Solutions for Disc Granulators in Organic Fertilizer Production Lines

by organic fertilizer production line

Disc granulators are widely used in organic fertilizer production lines due to their advantages, such as uniform granulation and low cost. However, in actual operation, they are susceptible to various factors, leading to various problems that affect production efficiency and product quality.

Improper control of raw material moisture is a primary challenge. If the moisture content is too high, the raw material will easily clump on the inner wall of the disc, forming large, adhered masses. This not only prevents proper granulation but also increases the difficulty of equipment cleaning. If the moisture content is too low, the raw material will have poor flowability, making it difficult to agglomerate into granules, resulting in loose and easily broken granules. To address this issue, precise control of the raw material moisture content using a moisture meter before granulation is required. Typically, the moisture content is maintained at a stable level of 25%-35%. If the moisture content is not within this range, it should be adjusted promptly using a dryer or humidifier.

Improper disc inclination and rotation speed can also cause problems. If the inclination angle is too large, the raw materials will stay in the disc too short, causing the particles to be discharged before they have time to fully round, resulting in irregularly shaped finished particles. If the inclination angle is too small, the raw materials will pile up, easily causing “sticking” and affecting normal equipment operation. Excessive rotational speed will subject the raw materials to excessive centrifugal force, preventing effective agglomeration. Too slow rotational speed will significantly reduce granulation efficiency. Generally, the disc inclination angle should be adjusted to 35°-45° and the rotational speed to 15-20 rpm, depending on the raw material characteristics. These parameters should be gradually optimized through trial production.

In addition, uneven mixing of raw materials can also affect granulation performance. If the organic raw materials and auxiliary materials are not fully mixed, nutrient imbalances in certain areas can lead to poor granulation quality and uneven particle size. This requires the use of high-efficiency mixing equipment before granulation to ensure that the raw materials are mixed uniformly to a level above 90%. Regular inspection of the mixing blades of the mixing equipment should also be performed to prevent blade wear that may reduce mixing efficiency.

In response to these common problems, a complete inspection mechanism needs to be established during production, and the operating status of the equipment and raw material indicators should be checked regularly, and the process parameters should be adjusted in time to ensure the stable operation of the disc granulator and improve the quality of the finished organic fertilizer.
