In agricultural production, BB fertilizer (blended fertilizer) and compound fertilizer are commonly used multi-nutrient fertilizers by farmers. However, they differ significantly in production processes, nutrient characteristics, and application scenarios. Choosing the right fertilizer is a key prerequisite for improving crop yield and quality. From a production process perspective, BB fertilizer production line s can be described as "simple mixing." They use large-particle urea, diammonium phosphate, and other single-element fertilizers or compound fertilizers as raw materials, completing physical mixing through mechanical stirring. There are no chemical reactions or granulation steps. The production equipment is simple, the cost is low, and the nutrient ratio can be adjusted at any time. In contrast, NPK compound fertilizer production line s involve a complex "chemical synthesis" process. The raw materials must first be crushed, and then re-granulated using an NPK...

In the NPK fertilizer production process , equipment failures can easily lead to reduced production capacity, substandard product quality, and even increased maintenance costs. The following provides precise troubleshooting solutions for three common faults: inaccurate ingredient mixing, poor granulation, and poor drying effect, helping to ensure efficient production operation. Inaccurate ingredient mixing is the core fault affecting fertilizer quality, manifested as a deviation of the nitrogen, phosphorus, and potassium ratio from the set value, with an error exceeding ±1%. The main causes include: raw material residue adhering to the weighing sensor, drift in the variable frequency speed control system parameters, and uneven feeding due to blockage at the hopper discharge port. To resolve this, first stop the machine and clean the sensor, then recalibrate it using calibration weights; check the variable frequency controller parameters and verify and correct them against the set ratio...

The selection of fertilizer production machine directly determines production efficiency, product quality, and operating costs. It's crucial to avoid the pitfalls of "blindly pursuing high-end" or "overly ambitious" approaches and instead build a scientific decision-making system based on actual needs. First, accurately identify core production requirements. The type of fertilizer must be clearly defined. Organic fertilizer production lines should prioritize the stability of fermentation turners and semi-wet material crushers; compound fertilizer production lines should focus on the accuracy of batching scales and the granulation effect of granulators; and bio-fertilizer equipment must ensure the temperature and humidity control performance of the fermentation tanks. Simultaneously, consider the scale of production capacity: small farms can choose mobile turners and manual packaging machines, offering low investment costs and high flexibility; medium-sized fert...

The continuous and stable operation of the NPK fertilizer production line is crucial for ensuring production capacity. Failures such as material jamming in the mixer, abnormal vibration in the granulator, and uncontrolled temperature in the dryer, if not handled properly, can easily lead to production interruptions, equipment damage, or even safety accidents, directly affecting the smooth progress of the NPK fertilizer production process . Scientific emergency handling should follow the principle of "stopping losses first, then investigating, and quickly repairing," balancing efficiency and safety. The core of equipment failure emergency handling is categorized and targeted measures. The mixer, as a key piece of equipment for raw material proportioning, often experiences material agglomeration and jamming. In this case, the machine must be stopped and the power disconnected immediately. Directly clearing the agglomerate by hand is strictly prohibited. The location of the jam...

NPK fertilizer formulation is not simply a mixture of nitrogen, phosphorus, and potassium. It's a scientific optimization process based on crop growth needs, soil fertility, and raw material characteristics. The core objective is to achieve nutrient supply and demand balance and improve fertilizer utilization. This principle is also the core technology behind NPK fertilizer production line s' customized production. Its formulation principle can be explained from three core dimensions: The nutrient requirements of crops are the core basis for formulation. Different crops have significantly different requirements for the ratio of nitrogen, phosphorus, and potassium: grain crops require high nitrogen to ensure photosynthesis and grain fullness, so the formulation is often "high nitrogen, medium phosphorus, and low potassium"; vegetable crops have a short growing season and concentrated nutrient requirements, requiring a balanced supply of nitrogen, phosphorus, and potass...

NPK compound fertilizers, due to their balanced nutrients and wide applicability, have become a core fertilizer in agricultural production. However, caking has long plagued the industry—caking results in poor flowability, inconvenient application, and reduced product value. Fertilizer caking is essentially caused by the dissolution and recrystallization of granule surfaces, forming "crystal bridges," or by granule adhesion due to moisture absorption and compression. Therefore, a comprehensive anti-caking system needs to be established at every stage of the NPK fertilizer production line . Raw material pretreatment is the foundation of anti-caking. In NPK production, the moisture content of hygroscopic raw materials such as urea and ammonium chloride must be strictly controlled. Before storage, the moisture content should be reduced to below 0.5%, and prolonged exposure to high humidity environments should be avoided. The formulation ratio needs to be optimized in the batching...
