Organic fertilizer manufacturing equipment includes: material processing equipment (such as crushers, mixers, batching scales, etc.), fermentation equipment (such as compost turners, composting machines, fermentation tanks, etc.), granulation equipment (such as granulators, dryers, coolers, screening machines, etc.), and packaging equipment (such as packaging machines, sealing machines, coding machines, etc.). These machines help improve production efficiency and product quality throughout the organic fertilizer manufacturing process. At the same time, different types of organic fertilizers and production requirements determine the selection of different equipment configurations.
I. Supporting Equipment for Organic Fertilizer Manufacturing
In a complete modern organic fertilizer production line, in addition to core equipment such as fermentation systems, crushers, granulators, and dryers, a high-performance supporting equipment system serves as the “arterial network” and “quality assurance system” that maintains continuous, automated, and environmentally friendly operation throughout the production line.
Zhengzhou Yizheng Heavy Machinery Equipment Co., Ltd. provides a complete range of high-performance supporting equipment specifically designed for modern fertilizer engineering, including dynamic batching machines, buffer bins, coating machines, conveyors, packaging machines, polishing machines, batching hoppers, solid-liquid separators, and more.
Since organic fertilizer raw materials are derived from a wide range of sources, such as livestock manure, crop straw, and municipal waste, they generally exhibit challenging physical characteristics, including high moisture content, strong corrosiveness, high adhesion, and excessive dust generation. Conventional auxiliary equipment often experiences technical problems under such harsh conditions, including belt slippage, pipeline blockage, inaccurate metering, and structural corrosion.
The supporting equipment system developed by Zhengzhou Yizheng Heavy Machinery incorporates comprehensive industrial-grade optimization featuring anti-corrosion, anti-adhesion, and dust-proof designs. All material-contact surfaces are specially treated with high-quality corrosion-resistant stainless steel (such as SUS304) or polymer anti-stick liners according to process requirements. The entire supporting equipment system operates in close coordination with the main production line and achieves integrated digital control through a PLC-based central control system, providing a solid foundation for fertilizer manufacturers pursuing large-scale production and stable fertilizer quality.
II. Working Principle
Each core supporting device operates efficiently in different sections of the organic fertilizer production line according to its unique industrial operating principles:
As a critical raw material pretreatment device, the solid-liquid separator utilizes screw extrusion or vibrating screening principles. A powerful screw shaft continuously pushes high-moisture livestock manure forward while a high-density stainless steel screen efficiently separates free water from solid fibers, reducing the moisture content of solid materials to the optimal fermentation range of 50%–60%.
2. Batching Hoppers and Dynamic Batching Machines
Batching hoppers are used to store various nitrogen, phosphorus, potassium, and trace element materials.
Dynamic batching machines employ a combination of continuous variable-frequency feeding and static/dynamic precision weighing sensors. As materials pass over the weighing bridge on the conveyor belt, weight and speed signals are transmitted in real time to the PLC controller, which automatically adjusts feeding rates to achieve highly accurate multi-material formulation ratios.
3. Conveyors and Buffer Bins
Conveyors (belt conveyors or bucket elevators) utilize friction between the drive pulley and conveyor belt or the mechanical lifting force of buckets to achieve seamless material transportation between process sections.
Buffer bins are installed before critical process sections such as granulation or packaging. Through gravity settling and internal anti-bridging mechanisms, they regulate material flow, compensate for speed mismatches between process stages, and prevent production interruptions caused by material blockages.
Newly formed fertilizer granules are conveyed into the polishing machine.
The equipment consists of two or more polishing discs rotating at high speed in the same direction. Under the combined effects of centrifugal force, friction, and gravity, granules are continuously rolled and polished, transforming irregular or elongated particles into smooth, spherical, and uniformly dense premium-quality fertilizer granules.
Operating on the principle of rotary drum coating, fertilizer granules form a uniform rolling material curtain inside the rotating drum.
Anti-caking agents, brightening agents, or microbial additives are evenly sprayed onto the particle surface through high-pressure nozzles, forming a dense protective layer that effectively prevents moisture absorption and caking while enhancing product appearance.
The packaging machine adopts static cumulative weighing and dual-speed feeding technology.
Once the target weight is reached, the bag-clamping cylinder secures the bag opening, the discharge gate opens, and the fertilizer is released into the packaging bag. The filled bag is then transferred via conveyor to the automatic sewing and sealing system for final packaging and finished product output.
III. Product Applications
The supporting equipment manufactured by Zhengzhou Yizheng Heavy Machinery Equipment Co., Ltd. offers excellent adaptability and is widely used in the following applications:
-Large-Scale Organic Fertilizer Production Lines
Used to transform fermented bulk materials into standardized, commercial bagged granular fertilizers while enabling fully automated material handling throughout the production process.
-Organic-Inorganic Compound Fertilizer and High-Concentration Compound Fertilizer Production
The combination of dynamic batching machines and batching hoppers ensures precise formulation control, preventing nutrient imbalance in fertilizer products.
-Livestock Farm Environmental Protection and Waste Treatment Centers
Solid-liquid separators can be directly connected to manure collection systems to perform manure dewatering. The separated solids are used for composting, while the liquid portion is directed to biogas systems or wastewater treatment facilities.
-High-Value Bio-Fertilizer and Controlled-Release Fertilizer Production
Polishing machines enhance the commercial appearance of fertilizer granules, while coating machines accurately apply functional coatings to extend nutrient release duration in soil.
IV. Product Features
High-Precision Metering and Accurate Formula Control
Both dynamic batching machines and packaging machines are equipped with imported high-precision weighing sensors and variable-frequency control systems. Weighing accuracy is maintained within 0.2%.
The system features automatic zero tracking and automatic drop compensation functions, ensuring that the nutrient content of every fertilizer batch fully complies with national industry standards.
Industrial-Grade Corrosion and Anti-Adhesion Design
To withstand the high-moisture and mildly acidic or alkaline environment of organic fertilizer production, all material-contact surfaces inside batching hoppers, buffer bins, and coating machines are manufactured from corrosion-resistant stainless steel or lined with ultra-high molecular weight polyethylene (UHMW-PE) anti-stick panels.
This effectively eliminates common industry problems such as chemical corrosion, material adhesion, and bridging.
Improved Granule Appearance and Higher Commercial Value
The polishing machine utilizes a unique process layout and achieves a granulation polishing rate exceeding 98% while generating virtually no dust.
The coating machine produces a uniform coating layer that significantly improves granule compressive strength and moisture resistance while creating a more attractive and consistent product appearance, substantially enhancing market competitiveness.
Enclosed Environmental Protection Design and Low Failure Rate
Conveyors and transfer chutes are designed with integrated sealed dust-proof covers and work in conjunction with the production line’s dust collection and ventilation system to eliminate dust leakage within the workshop.
Key transmission components such as gears and bearings are equipped with reinforced sealing and dust-proof protection, significantly extending maintenance intervals and overall equipment service life.
