What is high-tower granulation technology? High-tower granulation is an advanced compound fertilizer production process. Its core principle is melt spray self-forming. Raw materials such as urea, monoammonium phosphate, and potassium chloride are heated to 110-130℃ in a melting tank to form a highly fluid molten slurry. This slurry is then sprayed downwards from the top of a granulation tower...
My country produces a large amount of crop straw annually. Directly returning it to the field results in slow decomposition and susceptibility to pathogens. Converting it into commercial organic fertilizer is a highly efficient way to utilize its resources. Achieving this conversion hinges on three key technologies: straw softening treatment, application of rapid fermentation agents, and...
Organic fertilizer granules are highly susceptible to cracking, chipping, and even pulverization during the drying and cooling processes due to mechanical collisions and thermal stress. The key to protecting granule integrity lies in rationally setting the drum rotation speed, in conjunction with the air temperature curve and the internal lifting plate structure. This article provides an operable...
NPK 25-10-10 is a high-nitrogen compound fertilizer with a total nutrient content of 45%, significantly higher than phosphorus and potassium. This formula is suitable for use as a base fertilizer or top dressing for gramineous field crops such as corn, wheat, and rice, as well as leafy vegetables. High nitrogen promotes rapid stem and leaf growth, while appropriate amounts of phosphorus and...
On fertilizer production lines, the material produced by granulators does not directly become the finished product. It contains a mixture of fine powder, oversized particles, and qualified particles of varying sizes. The vibrating screen is the key equipment for solving this problem. Through the high-frequency vibration of multiple layers of screens, it precisely separates the material into...
What is Integrated Water and Fertilizer Management? Integrated water and fertilizer management is a modern agricultural technology that dissolves fertilizer in irrigation water and uses drip irrigation, sprinkler irrigation, and other systems to achieve “synchronous and precise supply of water and fertilizer.” It changes the traditional extensive “large-scale water and fertilizer” model, allowing...
Organic fertilizer production operates in a harsh environment characterized by high temperature, high humidity, and highly corrosive gases (ammonia, hydrogen sulfide, organic acids). Without effective protection, the steel structure of the equipment will severely corrode within 1-2 years, leading to problems such as breakage of the compost turner’s main shaft, peeling of the granulator’s inner...
In large-scale livestock farms, centralized straw processing areas, or municipal sludge composting sites, composting operations are often conducted in open, unpaved outdoor environments. In these situations, crawler type compost turners, with their excellent terrain adaptability, high processing efficiency, and economical fuel economy, become the ideal choice for windlass composting. This...
BB fertilizer is made by directly mixing various granular raw materials with different particle sizes and densities. The biggest quality challenge is component segregation. Vibration during transportation and packaging causes large particles to float and small particles to sink, resulting in uneven nutrient distribution within the same bag of fertilizer. Solving this problem requires more than...
In the production of high-concentration NPK compound fertilizer (total nutrients ≥45%), the choice of granulation process directly affects product quality, production costs, and return on investment. Currently, the two main technical routes—roller granulation (double roller extrusion granulator) and drum granulation (rotary drum granulator)—differ significantly in principle, energy consumption...
