How to adapt a BB fertilizer blender to different raw material characteristics?

BB fertilizer raw materials come in a variety of forms (granular, powdered, and fiber-containing). BB fertilizer blenders require targeted adjustments to accommodate these different raw material characteristics and avoid mixing problems.

For pure granular raw materials (such as urea and diammonium phosphate granules), which have relatively small density differences but are prone to rolling and stratification, the BB fertilizer blender should be equipped with guide plates within the mixer drum to guide the raw materials into upward and downward circulation and control the feed order. Adding the denser diammonium phosphate first, followed by the lighter urea, can reduce initial stratification. The speed can be appropriately reduced in the later stages of mixing to prevent excessive collisions between particles that could lead to breakage.

If the raw materials contain powdered ingredients (such as potassium chloride powder or trace element powder), a dustproof seal should be installed at the BB fertilizer blender feed port to prevent dust from escaping. Additionally, an atomizing humidifier (control the humidity to ≤15%) should be installed within the mixer drum. A small amount of humidification can enhance adhesion between the powdered raw materials and the granules, preventing dust from becoming suspended.

When the raw materials contain fiber organic fertilizer (such as fermented straw powder), it is necessary to use a paddle with a shearing function to prevent the fibers from entangled and clumping. At the same time, the fiber raw materials should be crushed to less than 3mm in advance to reduce mixing resistance. During the mixing process, the machine can be stopped and observed every 3 minutes. If fiber clumps are found, the paddle angle needs to be adjusted to enhance the shearing and dispersion effect to ensure that the fibers and granular fertilizer are fully integrated.

Controlling pellet strength in ring die granulators: Key to fertilizer transportation and storage

Pellet strength is a core performance indicator for fertilizer products. Ring die granulators require multi-step control to ensure pellets can withstand the pressure of transportation and stacking, minimizing breakage and loss.

First, consider the raw material ratio. If the organic matter content in production is too high (over 60%), binders such as clay and bentonite should be added (control the amount to 3%-5%) to increase the viscosity of the raw materials and lay the foundation for pellet strength.

If the proportion of inorganic fertilizer is high, the moisture content of the raw materials should be controlled between 14% and 16% to avoid pellet brittleness caused by too low a moisture content and easy sticking to the ring die granulator due to too high a moisture content.

Selecting the ring die granulator compression ratio is also crucial. The compression ratio (the ratio of the ring die aperture to the effective thickness) should be adjusted according to the fertilizer type. For organic fertilizers with high fiber content, a low compression ratio of 1:8-1:10 is recommended to prevent pellets from being too hard and easily broken. For compound fertilizers, a high compression ratio of 1:12-1:15 is recommended to enhance pellet density. During production, regular spot checks can be performed using a pellet strength tester. If the strength is insufficient, the steam supply to the conditioner can be temporarily increased (by 10%-15%).

In addition, the gap between the roller and the ring die should be controlled within a range of 0.1-0.3mm. A gap too large will cause the raw material to slip, resulting in insufficient pellet density; a gap too small will increase wear and affect pellet consistency. By synergistically controlling these three factors, the compressive strength of fertilizer pellets can be stabilized at above 20N, meeting transportation and storage requirements.

Malaysia Oil palm special compound fertilizer: the secret of increasing production

Malaysia, a tropical country in Southeast Asia, is famous for its rich palm oil resources. Oil palm trees thrive here, producing fruits that not only bring prosperity to the local economy, but also become an important pillar of Malaysian agriculture. The innovative application of special compound fertilizer for oil palm has brought revolutionary changes to the production improvement of this green gold.
 

NPK Fertilizer Production Line: A filling station where oil palm grows

 
In Malaysia, the NPK Fertilizer Production Line is playing its big role. This line can formulate a specific proportion of NPK compound fertilizer according to the needs of oil palm trees at different growth stages. Nitrogen fertilizer promotes leafy growth, phosphate fertilizer enhances root development, and potassium fertilizer enhances fruit quality. The synergistic effects of the three provide comprehensive nutrient support for the growth of oil palm.

Organic Fertilizer Production Line: Guardians of soil health

 
The application of Organic Fertilizer Production Line in Malaysia not only improves the quality of oil palm, but also contributes to the long-term health of the soil. By converting organic waste into organic fertilizer, these production lines promote microbial activity in the soil and improve soil structure, allowing oil palm trees to grow in a healthier environment.

Fertilizer Granules Compaction Machine: The key to improving fertilizer efficiency

 
In the process of Fertilizer production, the use of Fertilizer Granules Compaction Machine greatly improves the utilization efficiency of fertilizer. This type of granulator makes fertilizer raw materials into pellets through high pressure extrusion, which is not only convenient for fertilization operation, but also reduces the loss of fertilizer and improves the utilization rate of fertilizer.

Fertilizer drying and cooling machine: the guardian to ensure the quality of fertilizer

 
Rotary Dryer machines and Rotary Cooler machines play an important role in fertilizer production. They ensure that the quality of the fertilizer will not be affected by excessive humidity during the production process, and also ensure the stability and durability of the fertilizer. This is crucial for the production of oil palm special compound fertilizers as they need to remain stable in Malaysia’s humid climate.
 
Through the application of these advanced fertilizer production technologies and equipment, Malaysia’s oil palm industry is achieving a double improvement in yield and quality. This is not only a victory for agricultural technology, but also a strong demonstration of environmentally friendly farming practices. With the continuous optimization and popularization of these technologies, the sweet flavor of Malaysian oil palm will be more mellow and the yield will be higher.
