Composting in an Organic Fertilizer Production Line

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

In an organic fertilizer production line, composting is a core step in achieving both harmlessness and resource utilization of organic waste. Through microbial decomposition, raw materials like livestock manure and straw are transformed into nutrient-rich, mature materials, laying the foundation for subsequent processing.

The first step in composting is raw material preparation, requiring precise control of the key indicator, the carbon-to-nitrogen ratio. Among commonly used raw materials, straw and mushroom residue are high-carbon, while livestock manure is high-nitrogen. These materials should be mixed in a ratio of 25:1-30:1. For example, a mixture of 60% cow manure and 40% pulverized straw can meet microbial activity while minimizing nitrogen loss. Furthermore, the moisture content of the raw materials should be adjusted to 50%-60%. The material should be held firmly in the hand, with water between the fingers but not dripping. If it is too dry, water should be applied; if it is too wet, add dry straw or sawdust.

The composting process requires scientifically controlled environmental conditions. Windrow and trough composting are two common methods used in production lines. Windrow composting involves piling raw materials into long windrows 2-3 meters wide and 1.2-1.5 meters high. Windrow compost is turned every 2-3 days by a windrow compost turning machine to ensure adequate oxygenation within the windrow. Trough composting, on the other hand, takes place in sealed fermentation tanks, equipped with automated turning equipment to precisely control temperature and oxygen levels, making it suitable for large-scale production. During composting, the temperature must be maintained at 55-65°C, which kills insect eggs and pathogens and facilitates microbial decomposition of organic matter. If the temperature is too low, high-nitrogen raw materials should be added; if it is too high, turning should be used to reduce the temperature.

Determining the maturity of compost is crucial to ensuring the quality of subsequent products. Generally, after 20-30 days, the compost is mature when its color turns dark brown, it no longer has a manure odor but instead has a light earthy smell, and it is loose and free of noticeable lumps. At this time, the organic matter content of the composted material is greatly increased, and it is rich in nutrients such as amino acids and humic acid. It can not only provide nutrients for crops, but also improve soil structure. It is an indispensable “nutrient conversion station” in the organic fertilizer production line.

The impact of material moisture on flat die granulators in organic fertilizer production

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

In organic fertilizer production, flat die granulators are highly favored for their strong adaptability and low investment cost. However, the moisture content of the material directly determines the success and efficiency of granulation—it can be considered the “lifeline” of the process.

1.Excessively Low Moisture: Results in Failure to Form Pellets and Reduced Output

When the material is too dry (usually with a moisture content below 20%), its viscosity significantly decreases. Under the pressure of the rollers, the powdered material cannot bind effectively, leading to loose, poorly formed pellets or granules with very low strength that break easily.

2.Excessively High Moisture: Causes Blockage and Sticking, Halting Production

If the material is too wet (usually with a moisture content above 40%), it becomes too soft and overly sticky. During compression, the material adheres to the rollers and the flat die mold, forming a thick layer of paste that causes serious clogging.

3.Ideal Moisture Range

Generally, the ideal moisture content for materials processed by a flat die granulator falls within the range of 25%–35%. Within this range, the material exhibits optimal plasticity and viscosity. Therefore, to achieve the best performance of the flat die granulator, it is essential to accurately monitor and pre-treat the moisture content of the incoming material. This can be done by adding dry auxiliary materials (such as straw powder or rice husk powder) or returned material to reduce moisture, or by adding water or slurry to adjust overly dry material.

In summary, precise control of material moisture is key to unlocking the full potential of flat die granulators.
