I. Product Overview
With the growing awareness of environmental protection and the rapid development of green agriculture, the resource utilization of organic wastes such as livestock and poultry manure, crop straw, and municipal solid waste has become an important direction in the industrialization of modern agriculture. As a professional provider of fertilizer equipment and engineering solutions, Zhengzhou Yizheng Heavy Machinery Equipment Co., Ltd. has developed a high-efficiency organic fertilizer processing equipment system specifically designed to meet the requirements of large-scale, continuous, and automated production.
Organic fertilizer processing is a highly systematic project covering a complete series of processes, including raw material screening, raw material pretreatment, proportioning, crushing, mixing, granulation, screening, drying, cooling, and automatic packaging. Since different customers have different raw material characteristics, production processes, and production capacities, such as annual outputs ranging from 10,000 to 200,000 tons, the organic fertilizer processing equipment provided by Zhengzhou Yizheng offers a high degree of configuration flexibility and modular combination capability. The equipment adopts industrial-grade corrosion-resistant and wear-resistant designs, while critical components are manufactured from high-quality stainless steel or equipped with specialized anti-sticking liners. It can effectively withstand demanding operating environments characterized by high moisture and mildly acidic or alkaline conditions, making it an ideal choice for fertilizer manufacturers seeking to establish high-quality, environmentally friendly demonstration plants.
II. Working Principle
During the organic fertilizer processing procedure, specialized equipment in each process stage works in close coordination and performs its irreplaceable function based on scientific physical and mechanical transformation principles:
- Raw Material Pretreatment and Precision Crushing (Crusher)
Fermented organic raw materials often contain large agglomerates and coarse fibers. The crusher is mainly used to apply intensive impact, shearing, and size-reduction forces to large particles and block materials, converting them into uniformly sized fine powder that is easier to process in subsequent stages. This prevents equipment blockage and improves the efficiency of downstream processing.
- Multi-Component Homogenization and Proportioning (Mixer)
Various organic base materials, inorganic nutrients, and functional microbial agents are weighed according to the predetermined formulation and then fed into the mixer. The mixer is mainly used to thoroughly blend raw materials of different compositions. Driven by twin-shaft paddles or horizontal screw agitators, the materials undergo intensive convection and shearing, allowing multiple components to achieve a molecular-level uniform state within a very short period and ensuring consistent nutrient content in the finished fertilizer.
- Core Granule Formation (Granulator)
The granulator is used to convert the uniformly mixed raw materials into granules. Inside advanced granulation equipment, such as a stirring-tooth combination granulator or rotary drum granulator, the material is subjected to the combined action of high-speed mechanical force and centrifugal force generated by the rotating drum. Fine powder particles aggregate into spherical granules under the effect of surface tension, significantly increasing product density and making the fertilizer easier to store and transport.
- Dynamic Heat Exchange and Structural Hardening (Dryer and Cooler)
Freshly granulated particles contain relatively high moisture and have low structural strength. The material is conveyed through the upper feed inlet at the front of the dryer and enters the dryer. As the dryer drum rotates, the lifting plates raise and disperse the granules, allowing them to exchange heat with the hot air. After drying, the material is discharged through the lower outlet at the rear end onto the conveyor belt, achieving rapid moisture removal.
The granules then enter the cooler through the upper feed inlet at the front. Cold air is introduced to provide forced cooling. After cooling, the material is discharged through the lower outlet at the rear end onto the conveyor belt. The dryer and cooler are used to dry and cool the granules, allowing them to harden rapidly and return to ambient temperature for subsequent packaging and storage.
- Precision Classification and Finished Product Packaging (Screening Machine and Packaging Machine)
The screening machine is used to classify granules and remove impurities. The material is conveyed through the upper feed inlet into the screening machine. Screens with specific aperture sizes accurately separate qualified granules, oversized material, which is discharged through the lower outlet and returned to the crushing section, and undersized particles, which are returned to the granulation section, ensuring consistent finished product specifications.
Finally, qualified granules enter the automatic packaging machine for precise static weighing and bag sealing, completing the commercial packaging process.
III. Product Applications
The organic fertilizer processing equipment manufactured by Zhengzhou Yizheng Heavy Machinery Equipment Co., Ltd. offers broad material adaptability and is widely used in the following industrial processing applications:
- Resource Utilization of Livestock and Poultry Farming Waste
Suitable for the deep processing of waste from large-scale poultry and livestock farms, including chicken manure, cattle manure, pig manure, and sheep manure, converting harmful manure into high-value commercial organic granular fertilizer.
- Comprehensive Utilization of Agricultural Waste
Used to process agricultural residues rich in coarse fibers, such as crop straw, peanut shells, and rice husks. After fermentation and crushing, these materials are converted into soil conditioners and organic fertilizers.
- Production of Bio-Organic Fertilizer and Compound Fertilizer
Inorganic nutrients or biological microbial agents can be precisely added during the mixing and granulation stages to produce high-value specialized functional organic fertilizers.
- Treatment of Municipal Sludge and Urban Organic Waste
Applied in environmental protection projects for the harmless treatment, volume reduction, and resource recovery of sorted municipal solid waste and sewage sludge.
IV. Product Features
- Customized Configuration and Flexible Matching of Production Capacity
The equipment system overcomes the limitations of fixed production lines. Equipment can be flexibly selected and combined according to the customer’s specific production process, raw material characteristics, and available plant space, providing an optimized layout solution.
- Industrial-Grade Corrosion and Wear Resistance for Long Service Life
To address the high moisture content, mildly acidic or alkaline properties, and corrosive gases associated with organic fertilizer raw materials, material-contact components such as mixer liners, granulator stirring teeth, and dryer lifting plates are manufactured from thickened wear-resistant materials or treated with specialized corrosion-resistant coatings. This significantly reduces failure rates and extends equipment service life.
- Closed-Loop Production with High Capacity and Low Material Loss
Non-conforming granules separated during the screening stage can be automatically returned through the conveying system to the corresponding crushing or granulation section for reprocessing. This creates a closed-loop production system with virtually no material waste, maximizing material utilization and hourly production capacity.
- Excellent Granule Quality and High Physical Strength
Through the coordinated operation of granulation, drying, and cooling equipment, the produced fertilizer granules achieve a high granulation rate, rounded appearance, and excellent hardness. This effectively resolves the problems of moisture absorption, caking, and particle breakage during fertilizer transportation and storage.
Organic fertilizer processing equipment generally includes crushers, mixers, granulators, screening machines, dryers, and coolers. The specific selection of processing equipment and operating procedures varies according to different organic fertilizer production processes and production capacities.
