NPK fertilizer production lines are crucial for compound fertilizer production. As a key piece of equipment, BB fertilizer mixers, when integrated with the production line, significantly improve overall production efficiency and product quality. NPK fertilizer production involves processes such as raw material crushing, mixing, granulation, and drying. The mixing stage directly impacts the nutrient balance of the final product, and BB fertilizer mixers are a perfect fit for this requirement.
In the production line, raw materials processed by the fertilizer crusher are delivered to the BB fertilizer mixer via a fertilizer conveyor. Upon startup, the drive system drives the mixing shaft and blades, evenly mixing nitrogen, phosphorus, and potassium, laying a solid foundation for the subsequent granulation process.

While the new type two in one organic fertilizer granulator simplifies the organic fertilizer production process with its integrated design, it has more specific requirements regarding the adaptability of the processed materials.
Precise control of material particle size is crucial. Raw materials entering the new type two in one organic fertilizer granulator must undergo crushing and screening to ensure uniform particle size controlled within the 1-3 mm range. Large impurities or incompletely crushed lumps in the material will not only clog the equipment’s feed channel and die holes but may also accelerate the wear of internal components, affecting granulation continuity. Excessively fine powdery materials are prone to generating dust and will result in insufficient granule strength after molding.
Material moisture control is critical. The suitable material moisture content is 20%-30%, which needs to be fine-tuned based on the raw material composition. Excessive moisture content causes the material to easily clump together inside the machine, leading to a decrease in granulation rate and potentially causing die blockage. Insufficient moisture content results in a lack of viscosity, making it difficult to form through extrusion or granulation processes, and even if formed, it is prone to breakage.
The material composition ratio must be scientific. The carbon-to-nitrogen ratio of the raw materials should be maintained at 25-30:1. Avoid imbalances in the proportion of single high-nitrogen raw materials (such as poultry and livestock manure) or high-carbon raw materials (such as straw), otherwise the stability of the fertilizer effect after pelleting will be affected. At the same time, the proportion of fiber components in the material should not be too high. Excessive fiber can easily entangle equipment parts, requiring pretreatment to decompose some coarse fibers. If the raw material lacks viscosity, a suitable amount of natural binder can be added to improve the pelleting effect.
Furthermore, the material must be fully decomposed. Undecomposed raw materials may undergo secondary fermentation after granulation in the new type two in one organic fertilizer granulator, causing the pellets to expand and break, and potentially leading to seedling burn during fertilization.
In modern organic fertilizer production lines, the half-wet material crusher, as a crucial piece of equipment, demonstrates unique raw material processing capabilities.

It can directly process organic materials with a moisture content of 25%-50%, including livestock and poultry manure, filter mud, and straw. This characteristic not only simplifies the process flow but also significantly reduces the energy consumption cost of the entire organic fertilizer production line.
In practical applications, the half-wet material crusher forms a good synergistic effect with other organic fertilizer production equipment. The materials processed by it meet the requirements of subsequent processes in terms of particle size uniformity and moisture content, creating favorable conditions for the stable operation of the organic fertilizer granulator. Uniform raw material particle size not only improves granulation quality but also ensures the consistency of nutrients in the final product.
It is worth mentioning that this crushing equipment exhibits broad raw material adaptability in organic fertilizer production lines. Whether it’s highly viscous livestock and poultry manure or straw-like materials with high fiber content, ideal pulverization results can be achieved by adjusting the equipment parameters. This flexibility makes it an indispensable key piece of equipment in modern organic fertilizer production lines.
Modern fertilizer production is a highly systematic process involving a complete industrial chain from raw material processing to finished product packaging. Fertilizer production equipment can be divided into five key systems according to the technological process, each playing an indispensable role.
Raw Material Pretreatment System
Raw material pretreatment is the first process in fertilizer production. Crushers are responsible for breaking down bulk raw materials such as potash ore and straw to suitable particle sizes below 8 millimeters. Mixers uniformly blend raw materials including nitrogen, phosphorus, and potassium according to precise formulas, ensuring balanced nutrient distribution. Screening machines remove impurities through vibration screening and precision filtration, providing clean raw materials for subsequent processes.
Core Reaction and Fermentation System
Depending on the fertilizer type, core reaction equipment has distinct characteristics. Organic fertilizer production mainly relies on fermentation turners and maturation tanks, converting organic materials into stable humus through aerobic fermentation processes. Chemical fertilizer production uses equipment such as dissolution tanks, flotation machines, and crystallizers to achieve raw material purification and transformation. Chelation tanks effectively prevent precipitation of medium and trace elements, ensuring fertilizer quality.
Granulation and Forming System
Granulation is a core step in fertilizer production. Extrusion granulators form granules through high-pressure extrusion and are suitable for materials such as organic fertilizers and potassium chloride. Disc granulators utilize centrifugal force to precisely control particle size within the 2-4 mm range. Spray granulators produce water-soluble fertilizers through atomization and drying processes, while coating granulators can precisely control the coating of slow-release fertilizers. Drum granulators, with their large-scale production capacity, are the preferred equipment for NPK compound fertilizer production.
Post-treatment and Packaging System
After granulation, the fertilizer requires meticulous post-processing. A secondary screening machine ensures uniform particle size, while anti-caking equipment uses a special coating agent to prevent clumping during storage. Environmental protection equipment, including dust removal and wastewater treatment systems, ensures the production process meets environmental requirements. The final packaging process utilizes automated equipment for accurate metering and efficient packaging.
Modern fertilizer production lines achieve efficient and environmentally friendly large-scale production through the coordinated operation of various systems. Taking a typical NPK compound fertilizer production line as an example, the entire process from raw material pretreatment to finished product packaging can reach a daily output of 500 tons. The products fully comply with national quality standards, providing a reliable fertilizer guarantee for global agricultural production.
