In fertilizer granulation production, a key parameter directly determines the efficiency and energy consumption of the production line—the recycled material ratio. Understanding and optimizing it is one of the core means of reducing operating costs. Definition and Calculation Formula of Recycled Material Ratio The recycled material ratio refers to the ratio of the amount of material (including...
The essence of organic fertilizer fermentation is the decomposition of organic matter by aerobic microorganisms. The C/N ratio, moisture content, and oxygen supply are the three most critical physicochemical parameters, interconnected and indispensable. Mastering their optimal ranges, mechanical intervention methods, and sensory judgment techniques is fundamental to producing high-quality organic...
In organic fertilizer production, high-moisture materials (35%-45% moisture content) have always been a major challenge in granulation. Traditional extrusion or disc granulation requires moisture content below 30%, otherwise the granules are loose, easily stick to the walls, and drying energy consumption increases dramatically. In recent years, new organic fertilizer granulators based on...
NPK 20-10-15 is a high-nitrogen, medium-phosphorus, and medium-potassium compound fertilizer formula, with a total nutrient content of 45%. This formula has a significantly higher nitrogen content than phosphorus and potassium, making it particularly suitable for leafy vegetables, corn, rice, and other crops with high nitrogen requirements. Due to its high nitrogen content and urea as the...
In the competitive organic fertilizer market, granule appearance often determines the first impression. Smooth, rounded granules not only look better and are easier to spread, but also reduce powdering during transport. The rounding machine is the core equipment for achieving this “beautifying” effect. This article analyzes how to produce pearl-like fertilizer granules from three...
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...
