BB fertilizer (blended fertilizer), due to its flexible formulation and balanced nutrients, can accurately meet the needs of different crops and soils, making it an important choice for modern agricultural fertilization. Establishing an efficient and compliant BB fertilizer production line requires coordinating various aspects, including preliminary planning, equipment configuration, process design, and quality control, to ensure stable production and high-quality products.

Preliminary preparation is fundamental. First, market research and formula positioning must be completed.  Based on local major crops and soil fertility data, a core formula system should be determined to provide direction for subsequent production. Simultaneously, environmental impact assessments and production licenses must be obtained.  Site selection should prioritize areas with convenient transportation, close to raw material sources or sales markets. The site must also meet ventilation, moisture-proof, and anti-seepage requirements, and have sufficient space for raw material storage, production operations, and finished product stacking.
Equipment selection and rational layout are crucial. Core equipment includes an automatic batching system, mixer, screening machine, packaging machine, and dust removal equipment. The automatic batching system should be a high-precision model to ensure accurate nutrient ratios; the mixer should preferably be a BB fertilizer blender to ensure uniform mixing; and the accompanying dust removal equipment can effectively control dust pollution. The layout should follow the process flow of "batching—mixing—screening—packaging—finished product warehousing," reducing material transfer losses and improving production efficiency.
Process control and quality assurance are indispensable. A ​​strict raw material inspection system must be established in the production process to prevent unqualified raw materials from entering the warehouse; the automatic control system should accurately control the amount of each component during batching, and nutrient content should be sampled and tested after mixing; screening and impurity removal should be performed before finished product packaging to ensure uniform particle size. At the same time, a production log should be established to record information such as raw material consumption, production batches, and test results, enabling quality traceability.
In addition, professional operators should be employed, and equipment maintenance and production technology training should be provided to ensure the smooth operation of the production line. Through scientific planning and meticulous management, an efficient BB fertilizer production line that meets the needs of modern agriculture can be established.
