In fertilizer production, moisture management is a critical variable determining line configuration. Although mixing and granulation are involved in all cases, NPK blended fertilizers, conventional organic fertilizers, and bio-organic fertilizers have vastly different moisture requirements, which directly dictate equipment selection and process flow. NPK Blended Fertilizer Production...

The selling price of fertilizer granules depends not only on their N-P-K content but also on their visual appeal. Factors such as sphericity, surface smoothness, and particle size uniformity directly influence the purchasing decisions of distributors and the application experience of end-users. Surprisingly, these visual characteristics are often determined not by the main granulation unit...

What is the Moisture Content of Compound Fertilizer Granulation Feed? The moisture content of compound fertilizer granulation feed is not a fixed value, but depends on the granulation process used. For extrusion granulation (dry granulation), it is recommended to control the feed moisture content between 2% and 4%, which is the optimal range to ensure granule quality and stable equipment...

How to solve dust pollution in fertilizer production? Dust in fertilizer production mainly occurs during raw material crushing, batching and mixing, drying and cooling, and finished product screening. This dust not only causes material loss but also deteriorates the workshop environment, threatens the occupational health of employees, and, if emitted directly without treatment, will face...

Low pelletizing rate in disc granulators? Check These 5 Parameters First Low pelletizing rate in disc granulators is one of the most common problems encountered in production. When the pelletizing rate drops significantly (e.g., below 70%), don’t rush to suspect equipment malfunction. First, systematically check the following 5 key parameters: tilt angle, rotation speed, water spray, feed rate...

What is the suitable moisture content for organic fertilizer granulation raw materials? The recommended moisture content for organic fertilizer granulation raw materials is between 25% and 35%. Among these, 28%–32% is considered the “golden range,” representing the range where most materials achieve the best pelletizing effect and the highest granule quality. Why is 25%–35% the optimal range...

Why is a Disc Granulator the Preferred Choice for Small-to-Medium-Scale Production Lines with Limited Budgets? For small-to-medium-scale fertilizer production lines with limited budgets, the disc granulator is the preferred choice because it precisely meets the three essential needs of SMEs: low investment threshold, low operating costs, and simple operation and maintenance. Compared to other...

While the pricing of fertilizer granules appears to be based on N-P-K content, there is actually a hidden metric at play: particle size distribution. For granular fertilizers with the same nominal size range (e.g., 2–4 mm), products with a narrow particle size distribution perform exceptionally well during blending, mechanical sowing, and storage, allowing them to sell for 10–15% more;...

While the focus of fertilizer production lines often centers on granulators and packaging machines, the stable operation of the entire line is frequently determined by the “upstream processes” of fermentation turning and ingredient proportioning. Although these steps do not affect the appearance of the final product, they directly determine whether the material decomposes evenly and whether...

Fertilizer processing involves three sets of seemingly contradictory technical parameters: the more uniform the mixture, the more prone the granules are to breakage; the closer the particle sizes, the lower the formulation flexibility; and the more thorough the drying process, the higher the mortality rate of beneficial bacteria. The NPK Blending Fertilizer Production Line, the organic fertilizer...
