Organic fertilizer manufacturing equipment includes crushers, mixers, granulators, dryers, screening machines, packaging machines, and other equipment. Its production process generally includes raw material processing, fermentation treatment, formula preparation, granulation forming, drying and dehumidification, screening and grading, packaging and storage, and other steps. The specific process flow and equipment selection must be determined according to different types of organic fertilizer and production scale.

II. Working Principle
The operation of organic fertilizer manufacturing equipment follows the core logic of “aerobic degradation stabilization and standardized mechanical granulation.” The working principle of the complete production line can be divided into the following key process modules:
(1) Biological Fermentation and Deodorization Principle (Pretreatment Module)
The process begins in the fermentation area. The trough compost turner or wheel-type compost turner is the core equipment at this stage. Its working principle is to use a high-speed rotating drum to forcibly turn, scatter, and aerate the compost pile. Under sufficient oxygen conditions, aerobic microorganisms rapidly metabolize and decompose organic matter, causing the pile temperature to quickly rise to 55–75°C. This high-temperature process can thoroughly kill pathogenic bacteria, insect eggs, and weed seeds in the material, while accelerating moisture evaporation, transforming disordered waste into stable decomposed base material.
(2) Semi-Wet Material Crushing Principle (Refining Module)
After fermentation, the material may contain lumps and uneven fiber fineness. The semi-wet material crusher adopts a vertical shaft structure and uses high-speed rotating blades inside the machine to strongly impact and shear the material. Its principle is to use the kinetic energy generated by high linear speed to crush organic materials with a moisture content of 25%–50% into fine powder below 3 mm, ensuring excellent microscopic uniformity of the raw material entering the granulation process.
(3) Composite Granulation Principle (Core Forming Module)
This is a technical highlight of Zhengzhou Yizheng Heavy Machinery. The new organic fertilizer granulator integrates two mechanical principles: “stirring tooth extrusion” and “rotary drum rolling.”
- Stirring tooth section: High-speed rotating stirring teeth generate mechanical friction and collision on the material, allowing powdered material to form small nuclei under the action of moisture or binder.
- Rotary drum section: The nuclei continuously roll inside the rotating drum under the combined action of centrifugal force and gravity, adsorbing surrounding powder and wrapping layer by layer, finally forming round, high-strength spherical granules. This “two-in-one” process greatly improves the granulation rate of organic materials.
(4) Heat Exchange Drying and Cooling Principle (Setting Module)
Newly formed granules have relatively high moisture content and are not suitable for long-term storage. The rotary dryer exchanges heat with hot flue gas generated by the hot air furnace. The lifting plates on the inner wall of the drum lift the granules, allowing moisture to evaporate rapidly. The material then enters the cooler, where a large volume of cold air removes residual heat from the granules. Its principle is to use the stress solidification effect generated by rapid cooling to increase granule hardness and prevent condensation inside packaging bags due to temperature differences.
(5) Screening and Return Material Principle (Grading Module)
The rotary screening machine uses rotating screens to separate finished granules from unqualified oversized particles and fine powder. Qualified products enter the packaging scale, while unqualified products are returned to the granulation end through an automatic return conveyor for reprocessing, ensuring zero waste output across the entire production line.
III. Product Applications
The organic fertilizer manufacturing equipment of Zhengzhou Yizheng Heavy Machinery has a very wide range of applications and serves as a key link between waste conversion and modern agriculture:
- Large-scale livestock and poultry waste treatment: Widely used for manure treatment in large pig farms, chicken farms, cattle farms, and sheep farms, converting environmental management into direct economic returns and realizing a circular model of “integration of agriculture and animal husbandry.”
- Resource utilization of agricultural residues: Processes corn straw, wheat bran, rice husks, peanut shells, cottonseed hulls, and other materials. Through crushing and fermentation, carbon elements are returned to the soil, effectively improving the organic matter content of black soil.
- By-products from food and fermentation industries: Processes distiller’s grains, vinegar residue, soy sauce residue, sugar factory filter mud, medicinal residue, and other materials. These raw materials are rich in nitrogen, phosphorus, potassium, and protein components, making them high-quality sources for producing premium bio-organic fertilizer.
- Urban greening and environmental engineering: Carries out harmless composting and granulation of municipal sludge and landscaping waste such as fallen leaves and branches, with the resulting fertilizer used for urban landscape construction and nursery bases.
- Bio-organic fertilizer and formula fertilizer R&D: Used as a carrier for producing microbial fertilizers containing functional strains such as Bacillus subtilis, improving disease resistance and growth promotion effects, and supplying high-quality fruit and vegetable growing areas.
IV. Product Features
As a professional manufacturer in the fertilizer machinery field, Zhengzhou Yizheng Heavy Machinery integrates multiple innovative technologies into equipment R&D. The equipment produced has the following notable features:
First, industrial-grade corrosion-resistant design and long operating life.
The organic fertilizer production environment is characterized by high humidity and high corrosion from ammonia nitrogen and hydrogen sulfide. Yizheng Heavy Machinery uses high-quality manganese steel, stainless steel, or polymer anti-corrosion materials for key contact parts such as fermentation equipment blades, granulator liners, and dryer lifting plates. The machine body surface is treated with heavy-duty anti-corrosion paint, effectively resisting acid and alkali corrosion and ensuring an ultra-long service cycle under harsh working conditions.
