In October 2024, Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. successfully completed the installation and commissioning of a powder fertilizer production line tailored for a Malaysian client, officially entering the large-scale production stage. This production line focuses on the refined processing needs of powder fertilizers, integrating core processes such as raw material feeding, crushing, screening, and conveying. With efficient equipment configuration, compact layout design, and stable product quality, it provides local fertilizer production enterprises with a one-stop powder processing solution, helping to improve agricultural production efficiency and fertilizer utilization.
Production Line Configuration and Core Equipment Analysis
The entire powder fertilizer production line follows a closed-loop design of “raw material pretreatment – refined processing – finished product conveying.” Equipment selection is tailored to the characteristics of powder fertilizer production, the process is smoothly connected, and each unit works synergistically to fully ensure uniform product fineness and purity standards.
Raw Material Feeding and Conveying Unit: Stable Supply as the Foundation The production line starts with a forklift feeding hopper. The hopper features a large-capacity design to accommodate the rapid feeding of bulk raw materials. The feed inlet is equipped with spill-proof baffles and buffer devices to reduce material loss due to airflow and prevent large impurities from entering. Raw materials are smoothly transferred to subsequent processing stages via a 9-meter belt conveyor. The conveyor uses food-grade wear-resistant rubber belts with an anti-slip surface. The operating speed is adjustable via a frequency converter (0.8-1.5 m/s), achieving a conveying efficiency of 6 tons/hour, ensuring a continuous and stable supply of raw materials to meet the full-load operation requirements of the production line.
Core Grinding Unit: Fine Grinding Ensures Perfect Powder
The grinding process utilizes a 1500-type vertical crusher, the core equipment for powder production. It employs a combined “high-speed impact + grading crushing” process, with a rotor speed reaching 3000 r/min. The hammers are made of high-chromium alloy, achieving a hardness of HRC58 or higher after heat treatment, providing exceptional wear resistance. It can crush lumpy raw materials (particle size ≤80mm) into uniform fine powder of 100-200 mesh (0.075-0.15mm), achieving a grinding efficiency of 5 tons/hour. The equipment features a built-in grading screen, which can be flexibly replaced according to customer requirements for powder fineness. It is also equipped with an overload protection device that automatically shuts down the machine when hard impurities are mixed in with the raw materials, preventing equipment damage and ensuring production safety.
The crusher adopts a sealed design, coupled with a negative pressure dust collection interface, effectively reducing dust leakage during grinding, improving the production environment, and meeting local Malaysian environmental standards. The equipment’s operating noise is controlled below 78dB, achieving low-noise and high-efficiency production.
Grading and Screening & Finished Product Conveying Unit: Strict Quality Control and High-Efficiency Output
The crushed material is transferred via a 12-meter belt conveyor to a 2.0×6.0-meter drum screen. This equipment uses a single-layer high-precision screen design, and the screen aperture can be customized according to the fineness requirements of the finished product. Through the uniform rotation of the drum (18 r/min), substandard coarse particles are screened and separated, while qualified fine powder passes through the screen and enters the subsequent conveying stage. The screening efficiency reaches 5.5 tons/hour, and the finished product qualification rate is consistently above 99%. The separated coarse particles can be returned to the crusher for reprocessing via a return device (optional for customers), improving raw material utilization.
Qualified powder is conveyed to the finished product storage or packaging area via an 8-meter belt conveyor. The belt conveyor uses a fully sealed cover design to prevent the powder from absorbing moisture, clumping, or generating dust during transportation, ensuring product purity and a clean production environment. The production line can be flexibly integrated with finished product silos, automatic packaging machines, and other downstream equipment according to customer needs, achieving fully automated operation from raw material processing to finished product delivery.
Core Advantages and Adaptability of the Production Line:
Outstanding Refined Processing Capabilities: The precise combination of a 1500-type vertical crusher and a high-precision drum screen ensures uniform powder fineness and no impurities, meeting the application requirements of different crops for powdered fertilizers, resulting in faster fertilizer dissolution and higher absorption efficiency.
Compact Layout and Strong Adaptability: The production line adopts a modular and compact design, requiring only 400 square meters of space, saving 25% compared to traditional powder production lines, and is suitable for the limited space conditions in Malaysian factories; the equipment can flexibly adapt to the processing of various materials such as organic fertilizers, compound fertilizers, and micronutrient fertilizers, offering extremely high versatility.
High Efficiency, Energy Saving, and Environmental Protection: Core equipment uses energy-saving motors, reducing energy consumption by 12% compared to conventional equipment with the same capacity; the fully sealed design and dust removal system effectively control dust pollution, achieving green production.
Looking ahead, the company will continue to focus on the production needs of different regions, optimize equipment performance and process solutions, and provide global customers with more targeted powder fertilizer production line solutions to contribute to the high-quality development of the agricultural industry.
Complementary Technologies for a Complete Product Portfolio
This powder fertilizer production line represents a specialized segment of the modern fertilizer processing machine industry. It expertly addresses the market need for fine, highly soluble fertilizer powders. This successful project illustrates how specialized solutions fit into a broader ecosystem of fertilizer production machine technologies.
While this line is designed for powder, many producers also require granulated products for different applications. This is where other specialized equipment comes into play. The npk fertilizer manufacturing process, for instance, often requires fertilizer granules compaction via a roller press granulator production line using a fertilizer compactor. Alternatively, for a wet granulation approach, a rotary drum granulator (or drum granulator) is used. Similarly, an organic fertilizer disc granulation production line or a flat die pelleting machine might be chosen to shape organic compost into granules. Each of these systems—powder processing, dry compaction, or wet granulation—serves a distinct market niche and product specification, demonstrating the diversity of equipment available within the npk manufacturing process and organic fertilizer production.
Thus, a manufacturer’s complete offering is built by integrating multiple, targeted production lines, enabling them to supply both the powder and granular fertilizers that modern agriculture demands.
