Fertilizer and water integration is transitioning from an “optional technology” to a standard feature of farmland irrigation. In this process, liquid fertilizers, with their advantages of being ready to use, precise, and easy to transport, are seen by the industry as the next growth driver after solid fertilizers. To truly achieve seamless integration of liquid fertilizers with irrigation...
In the production of compound fertilizers and organic fertilizers, the appearance of the granules directly affects the product’s marketability and the customer’s first impression. Many manufacturers find that granules that appear round and plump after granulation become dull, rough, or even powdery after drying. The problem often lies in two easily overlooked stages: cooling and polishing. This...
What is Bio-organic Fertilizer? Bio-organic fertilizer refers to a new type of fertilizer that combines specific functional microorganisms (such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria, potassium-solubilizing bacteria, and antagonistic bacteria) with well-rotted organic fertilizer carriers, processed in a factory setting. Its essential difference from ordinary organic...
In compound fertilizer production, granule strength directly determines the product’s breakage resistance, transportation losses, and disintegration performance during application. Too low a strength results in easy powdering and clumping after packaging; too high a strength may affect crop absorption. By optimizing five key parameters—rotation speed, binder ratio, temperature fluctuation...
Disc granulators have become the mainstream equipment for small and medium-sized organic fertilizer plants due to their simple structure, controllable granulation, and low investment cost. However, many operators find that the particle size of the same material varies greatly and is difficult to stabilize. In fact, controlling particle size is not mysterious—by mastering three key...
In organic fertilizer production, granulation rate directly determines production capacity and cost. Every 10% increase in granulation rate reduces return material by nearly one-third and overall energy consumption by 15%-20%. However, many manufacturers are hampered by the problem of “more powder, less granules.” In fact, improving granulation rate is not complicated; the key lies in four...
In the landscape of modern precision agriculture, water-soluble fertilizers (WSF) are becoming a focal point for fertilizer manufacturers and large-scale growers due to their superior nutrient utilization and extremely high added value. Compared to traditional compound fertilizers, water-soluble fertilizers are often hailed as “agricultural supplements,” with profit margins per ton typically...
In traditional fertilizer granulation processes, the drying and cooling system is the most energy-intensive, space-consuming, and environmentally demanding part of the entire production line. The emergence of the new twin-roll extrusion granulator, with its “no room temperature drying required” technical feature, is redefining the efficiency limits of small- and medium-scale fertilizer production...
With the development of smart agriculture, slow-release fertilizers have become a core means of improving fertilizer utilization. Coating technology is not just about “dressing” fertilizer, but also a combination of microscopic fluid mechanics and materials science. Evolution of Coating Materials: From Sulfur to Biodegradable Polymers The coating material determines the...
With the increasing demands for fertilizer granule appearance and quality in modern agriculture, older plants often face the dilemma of choosing between disc granulators and drum granulators when expanding or upgrading their facilities. While both fall under the category of agglomeration granulation, they differ significantly in their technical logic, finished product morphology, and energy...
