Organic fertilizer supporting production equipment

Organic Fertilizer Supporting Production Equipment. 

I. Product Overview

In modern industrial organic fertilizer production, the key to transforming a wide variety of organic wastes with significantly different physical characteristics—such as poultry manure, cattle manure, swine manure, crop straw, and municipal organic waste—into standardized, marketable, high-quality fertilizers lies in establishing a scientifically designed and fully integrated supporting production equipment system.

Leveraging its extensive expertise in fertilizer engineering, Zhengzhou Yizheng Heavy Machinery Equipment Co., Ltd. provides customers with highly efficient, reliable, and flexible complete supporting equipment solutions tailored to diverse raw material characteristics and production process requirements.

The organic fertilizer supporting production equipment system replaces traditional rigid equipment layouts by integrating core machinery—including crushing equipment, mixing equipment, granulation equipment, drying equipment, and screening equipment—into a modular production system. Since different organic raw materials vary greatly in moisture content, fiber length, viscosity, and hardness, the greatest advantage of this production line lies in its fully customizable configuration capability. Dedicated equipment combinations can be configured for different raw materials, such as poultry manure and cattle manure, allowing the entire production line to operate continuously under optimized process conditions while maximizing raw material utilization, achieving environmentally friendly waste treatment, and creating greater economic value.

II. Working Principle

During operation, each supporting machine within the organic fertilizer production system is closely interconnected through the conveying system. Every unit performs its specific industrial function according to the physical transformation requirements of the material.

1. Raw Material Pre-Treatment and Fine Crushing (Specialized Crushing Equipment)

After fermentation, the raw material enters the crushing section.

For poultry manure organic fertilizer production, high-speed vertical crushers or chain crushers efficiently impact and crush hardened dry poultry manure.

For cattle manure and other materials containing high fiber content and high viscosity, specialized semi-wet material crushers are employed. High-speed wear-resistant blades and rotors generate intensive cutting and tearing forces to process high-moisture, fibrous materials into uniformly fine particles without clogging.

2. Multi-Component Molecular-Level Mixing (Mixing Equipment)

The crushed organic powder, together with additional inorganic nutrients (N, P, K) or beneficial microbial inoculants, enters the mixer.

Driven by high-efficiency twin-shaft mixing paddles or horizontal ribbon agitators, the materials undergo intensive convection, shearing, and cross-mixing within the mixing chamber, producing an exceptionally uniform blend that ensures every fertilizer granule contains a consistent nutrient composition.

3. Core Granule Formation and Particle Shaping (Granulation Equipment)

The uniformly mixed material then enters the granulation stage.

For poultry manure fertilizer production, spherical granulators—such as stirring-tooth combination granulators or integrated rotary drum polishing granulators—are typically used. Under the combined action of high-speed stirring teeth and centrifugal force generated by the rotating drum, the material rapidly forms dense, spherical granules with smooth surfaces.

For cattle manure fertilizer production, specialized dual-roll extrusion granulators may be selected according to the material’s fiber characteristics. These machines utilize mechanical extrusion and shearing principles to produce high-quality granules specifically suited to cattle manure.

4. Dynamic Heat Exchange and Rapid Moisture Removal (Rotary Drying Equipment)

Freshly formed granules contain relatively high moisture and have limited mechanical strength.

The granules are conveyed through the upper feed inlet into the rotary dryer. Inside the dryer, specially designed lifting flights continuously raise and disperse the granules as the drum slowly rotates, creating a uniform material curtain that exchanges heat efficiently with either co-current or counter-current hot air supplied by the hot air furnace.

After drying, the material is discharged through the lower outlet onto the conveyor, where moisture content is reduced to safe storage levels while particle strength is significantly improved.

5. Precision Classification and Closed-Loop Recycling (Screening Equipment)

After drying and cooling, the granules enter the screening section.

The material is conveyed through the upper inlet into the rotary screener, where rotating drum screens with specifically designed mesh openings and inclination angles accurately classify the particles.

Qualified granules proceed directly to the packaging section.

Oversized particles are discharged through the lower outlet and conveyed back to the crushing section for reprocessing.

Undersized particles are returned to the granulation system as seed material, creating a zero-waste closed-loop recycling process throughout the production line.

III. Product Applications

The organic fertilizer supporting production equipment manufactured by Zhengzhou Yizheng Heavy Machinery Equipment Co., Ltd. is widely used in organic waste recycling and modern fertilizer manufacturing industries.

- Poultry Manure Organic Fertilizer Production

Dedicated poultry manure crushers, spherical granulators, and rotary dryers are configured to process nitrogen-rich, easily compacted poultry manure into high-efficiency, premium-quality spherical organic fertilizers.

- Cattle Manure Organic Fertilizer Production

For cattle manure characterized by high fiber content and fluctuating moisture levels, high-shear crushing equipment combined with highly adaptable extrusion granulators effectively overcomes fiber bonding challenges and ensures stable granulation performance.

- High-Value Bio-Organic Fertilizer and Microbial Fertilizer Production

Precision temperature control and corrosion-resistant designs are incorporated into the mixing and granulation processes to maximize the survival rate and biological activity of beneficial microorganisms.

- Municipal Sludge and Organic Waste Treatment Projects

High-capacity conveying systems combined with efficient anti-adhesion and dust collection equipment convert various municipal organic wastes into safe, environmentally friendly soil conditioners.

IV. Product Features

- Flexible Equipment Configuration Based on Raw Material Characteristics

The greatest advantage of this supporting equipment system is its flexible configuration philosophy.

Rather than applying a standardized solution, we carefully analyze each customer’s raw material characteristics—such as the differences between poultry manure and cattle manure—and select the most suitable crushing, granulation, drying, and other processing equipment to maximize production efficiency while avoiding capacity limitations caused by improper equipment selection.

- Highly Coordinated System with Bottleneck-Free Production

The conveying system and all major processing equipment—including crushing, mixing, granulation, drying, and screening units—are precisely matched in capacity and integrated through electrical interlock control.

Balanced material flow between each processing stage eliminates localized material accumulation and idle operation, ensuring exceptionally smooth production with outstanding overall efficiency.

- Industrial-Grade Corrosion and Wear Resistance

Organic fertilizer raw materials are typically characterized by high moisture content and mildly acidic or alkaline corrosive properties.

Critical components—including mixer liners, granulator stirring teeth, dryer lifting flights, and screener frames—are manufactured using thickened wear-resistant, corrosion-resistant materials or lined with ultra-high molecular weight polyethylene (UHMW-PE) anti-adhesion panels, fundamentally eliminating problems such as material buildup, bridging, and premature equipment corrosion.

- Energy Saving, Reduced Consumption, and Environmentally Friendly Production

The airflow passages and thermal structure of the rotary dryer have been scientifically optimized to significantly improve thermal efficiency while substantially reducing fuel consumption.

Combined with enclosed conveying pipelines and cyclone dust collection systems, the entire production process operates with virtually no dust emissions or secondary pollution, enabling customers to meet environmental compliance requirements with ease while establishing high-quality green demonstration fertilizer plants.
