In BB fertilizer (blended fertilizer) production, the BB fertilizer mixer is a key piece of equipment that determines product quality. Its core function is to evenly blend multiple raw materials of varying density and particle size into a nutrient-consistent fertilizer, directly impacting subsequent fertilization effectiveness.
In terms of equipment structure, mainstream BB fertilizer mixers mostly adopt a closed-cylinder design with an internal mixing assembly. The cylinder is typically positioned horizontally, with the mixing assembly driven by a motor. Some BB fertilizer mixers also feature forward and reverse rotation to reduce residual material in the cylinder. The feed inlet is typically located at the top of the cylinder, and the discharge outlet at the bottom. Some models feature an observation window for easily monitoring the mixing status.
During operation, raw materials such as urea, monoammonium phosphate, and potassium chloride are introduced into the mixing cylinder according to the formulated ratio. The rotating mixing assembly propels the raw materials: the screw conveys the raw materials from both ends toward the center, the paddles shear and stir the raw materials, and the guide plates facilitate convection, ensuring full contact between raw materials with density differences of 30%-50%. The entire process does not require the addition of adhesives, and mechanical force is used to achieve “small particles filling gaps and large particles colliding with each other”, ultimately achieving a uniform mixing effect.
Chain crushers are not limited to organic fertilizer production; they also play a vital role in a variety of industries, including chemicals, building materials, and mining. They are truly versatile tools for material crushing in various industries, their flexible adaptability enabling them to deliver outstanding performance in diverse production scenarios.
In the chemical industry, they can pre-process and crush various medium-hardness industrial raw materials (such as sulfur lumps and soda ash agglomerates), providing uniformly sized materials for subsequent chemical reactions or processing steps. This prevents incomplete reactions caused by uneven raw material size and improves the quality and stability of chemical products.
In the building materials sector, chain crushers offer efficient crushing of materials such as limestone and shale. They can adjust the output particle size to meet the diverse particle size requirements of building materials production, such as cement and bricks.
In the mining industry, their high adaptability is particularly evident when dealing with ores of varying hardness, allowing crushing parameters to be adjusted based on the ore’s characteristics to ensure optimal crushing results.
In addition, this chain crusher can also be used in scenarios such as agricultural fertilizer crushing. With its wide applicability, it has become an important equipment in the material crushing process of various industries.
Many fertilizer companies switch product categories based on market demand. However, if the compatibility of the fertilizer granulator machine with the fertilizer type is neglected, problems such as reduced granule quality and frequent equipment failures can occur.
For organic fertilizers (including straw and fermented manure), the key requirement is “adaptability to the fiber raw material and avoid entanglement and machine blockage.” Flat die granulators or rotary drum granulators are preferred. The vertical extrusion design of the flat die cuts long fibers, and the trapezoidal, non-slip rollers reduce fiber entanglement. Rotary drum granulators use rolling to form the granules, and the lifting plate evenly lifts the fiber material to avoid localized accumulation.
For compound fertilizers (containing phosphate rock and potassium chloride), the key requirements are “high granule hardness and transport resistance.” The high compression ratio of the ring die granulator allows hard mineral raw materials to be extruded with a compressive strength of over 15N, meeting the requirements of long-distance transportation.
For biofertilizers (containing functional microbial agents), the key principle is “low-temperature granulation to protect the activity of the agents.” A flat die granulator (chamber temperature ≤ 40°C) or a disc granulator (rolling, no high-temperature extrusion) can prevent inactivation of microbial agents.
For slow-release fertilizers (including coating materials), “smooth granules suitable for subsequent coating” are required. The rolling forming method of a rotary drum granulator produces smooth, uniformly sized granules, which prevent the coating from detaching during coating.
How to Achieve Efficient Granulation Through Hydraulic Technology? Explore the Unique Advantages of High-Pressure Granulation
Technological Breakthrough in High-Pressure Granulation
In today’s granulation technology field, the hydraulic double roller granulator has become essential equipment across numerous industries due to its unique working principle and exceptional performance. This innovative fertilizer roller press machine utilizes hydraulic systems to drive counter-rotating pressure rollers, applying extreme pressure to materials, causing plastic deformation and bonding to achieve highly efficient compaction granulation.
The double roller press granulator serves as a versatile NPK fertilizer granulator for chemical production and equally functions as an effective organic fertilizer granulator for biological materials. Unlike the tumbling action of a rotary drum granulator that forms spheres through agitation, this press technology creates granules through direct compression. Within a complete NPK production line, the roller press system provides distinct advantages for specific material formulations, offering an alternative granulation method that complements other equipment for comprehensive production flexibility.

Technological Innovation and Process Advantages
The core technical advantage of hydraulic roller granulators lies in their unique hydraulic drive system and precision control technology. Compared with traditional granulation equipment, hydraulic systems can provide more stable and precise pressure control, ensuring each particle has consistent density and strength. This high-pressure granulation method requires no binder additives, relying entirely on the material’s own plastic deformation to achieve particle formation, ensuring product purity while reducing production costs.
More importantly, while improving production efficiency, hydraulic roller granulators also feature excellent energy utilization efficiency. Their modular design makes equipment maintenance more convenient, while the intelligent control system significantly reduces operational difficulty. From fertilizers to chemical products, from metallurgical raw materials to food additives, this innovative granulation equipment is providing more efficient and reliable granulation solutions for various industries.
The core of aerobic fermentation of organic fertilizers lies in uniform oxygen supply and temperature-controlled composting. The site adaptability of compost turning equipment directly determines fermentation efficiency and production flexibility. Windrow compost turning machines, with their trackless mobility and all-terrain adaptability, are a perfect fit for the diverse fermentation scenarios in the fertilizer industry.
From a structural perspective, the core advantage of windrow compost turning machines lies in the synergy between their crawler chassis and flexible turning mechanism. Their wide rubber tracks provide a large contact area and low ground pressure, preventing the vehicle from getting stuck even in muddy composting areas or gravel surfaces after rain, eliminating the need for pre-leveling. The chassis’ steering system supports 360° steering, making it easy to navigate obstacles such as raw material piles and equipment around the fermentation area.
In terms of the turning mechanism, most windrow compost turning machines are equipped with double-auger or blade-type turning components, capable of turning compost up to 1.2-2 meters deep and covering compost piles up to 3-5 meters wide. During operation, the equipment slowly moves along the fermentation pile. The turning components throw the bottom material upward and disperse it to the sides, creating a “rolling up and down, mixing side to side” effect. This not only provides sufficient oxygen for aerobic bacteria but also quickly dissipates the heat generated by fermentation.
For fertilizer companies, the value of a windrow compost turning machine lies not only in its flexibility but also in its ability to accommodate multiple fermentation batches. For example, the same site can simultaneously process both a “fresh feed pile” and a “mature compost pile,” allowing the equipment to flexibly switch between different piles, resulting in fermentation efficiency improvements of over 30% compared to track-type compost turners.
As the fertilizer industry upgrades toward “precision and functionalization,” demand for functional fertilizers such as slow-release fertilizers, biofertilizers, and trace element compound fertilizers has surged. The production of these fertilizers places special demands on granulators, balancing functional retention and granule formation.
For slow-release fertilizer production, fertilizer granulators must meet the dual requirements of “granule formation” and subsequent coating. For example, when producing sulfur-coated slow-release fertilizers, the granulation process requires producing base granules with a smooth surface and uniform hardness. The “rolling forming” feature of a rotary drum granulator is perfectly suited for this purpose. By controlling the drum speed (8-12 rpm) and the amount of binder used, the granules are naturally rounded and smooth. Some granulators also feature a “pre-cooling section” at the discharge port to reduce the granule temperature to below 30°C, paving the way for subsequent coating and preventing the coating material from melting and becoming ineffective due to high temperatures.
For compound fertilizers containing trace elements, fertilizer granulators must address the issue of uneven trace element distribution. These fertilizers contain low concentrations of trace elements such as zinc, boron, and iron. Inhomogeneous mixing can lead to nutrient deficiencies in some granules. In this case, the low-speed extrusion design of a flat die granulator is optimal. After thoroughly mixing the trace elements with the base raw materials in a twin-shaft premixer, the low-speed rollers slowly extrude the granules into shape, minimizing material separation and ensuring a trace element content variation of ≤0.1% per granule, thus preventing functional deficiencies.
For biofertilizers, the granulator’s low-temperature performance is crucial. Flat die and disc granulators utilize a low-friction, no-high-temperature extrusion design to maintain a temperature within the granulation chamber below 40°C, ensuring the survival rate of the microbial inoculant.
For manufacturing companies, equipment performance and cost control are crucial. Disc granulators excel in both areas, making them a powerful tool for enhancing competitiveness.
First, they offer exceptional energy efficiency. Compared to traditional granulation equipment, they consume less energy. Long-term use can save companies significant energy costs and effectively reduce production and operating costs. Second, disc granulators offer high production efficiency and enable continuous production. Depending on production needs, hourly output can range from several tons to tens of tons, meeting the production needs of companies of all sizes and helping them quickly complete production tasks.
Disc granulators offer even greater advantages in granulation quality. They produce highly uniform, strong, and resistant granules, ensuring high product quality for fertilizers, mineral powders, and chemical raw materials. Furthermore, they are easy to operate, requiring minimal training for operators to master their operation. This reduces production risks associated with complex operations. Maintenance is also relatively simple, further reducing management costs.
Standing at the crossroads of fertilizer production, many agricultural entrepreneurs face this critical decision: Should they invest in an organic fertilizer production line or choose an NPK compound fertilizer production line? This choice not only affects the initial investment but also shapes the company’s future market positioning and development direction.
Understanding the Fundamental Differences
Organic fertilizer production lines focus on transforming biomass materials into nutrient-rich fertilizers through natural processes including fermentation, crushing, and granulation. In contrast, NPK fertilizer production lines represent precision engineering at its finest, dedicated to manufacturing compound fertilizers with exact nutritional specifications through sophisticated NPK fertilizer manufacturing process technology.
The heart of NPK manufacturing begins with precise formulation using advanced fertilizer mixer machine and NPK blending machine equipment. These systems ensure homogeneous distribution of nutrients before the material enters the granulation phase. The core NPK production process employs specialized granulation technology, where the NPK fertilizer granulator machine – whether disc granulator, ring die granulator, or other NPK granulation machine variants – transforms powdered blends into uniform granules through advanced fertilizer granulation principles.
For specific applications, NPK bulk blending machine systems provide flexible formulation capabilities, while the disc granulator machine utilizes centrifugal force to create spherical granules ideal for precise application. The complete NPK fertilizer production lineintegrates multiple NPK fertilizer machine units, each optimized for specific stages of the manufacturing of NPK fertilizer.
