The chain compost turner represents a significant advancement in modern composting technology, addressing efficiency bottlenecks in processing large-scale organic waste through its unique design.
Working Principle and Advantages
The chain compost turner represents a significant advancement in organic processing equipment, adopting a continuous conveying composting design that enables uninterrupted fermentation operations. This versatile compost fertilizer machine offers superior operational flexibility compared to traditional trough-type systems, operating without the constraints of fixed fermentation tanks.
As one of the essential equipments required for biofertilizer production, this machine efficiently performs windrow fermentation in open areas, making it particularly suitable for large-scale operations. When integrated with other fertilizer production machine components such as the double roller press granulator and disc granulation production line, it creates a comprehensive system capable of handling the complete npk fertilizer production process.
While the large wheel compost turning machine serves similar purposes for certain applications, the chain compost turner stands out for its efficiency in large-scale organic fertilizer production bases and organic waste treatment centers, providing a robust solution for modern agricultural needs.
This equipment significantly enhances production efficiency while reducing operational costs in organic fertilizer manufacturing facilities.
Main technical advantages include:
- Large processing capacity, single machine daily processing capacity up to 500-2000 cubic meters
- Turning depth up to 1.5-2 meters, ensuring thorough fermentation of deep materials
- High degree of automation, reducing labor costs
- Adaptable to various complex terrains and working environments
Raw Material Processing Capability
Livestock and Poultry Manure
Includes high-density organic materials such as chicken manure, pig manure, cow manure, and sheep manure. The powerful turning of the chain compost turner can break up the compacted state of manure. Through ventilation and temperature increase during the turning process, it effectively kills pathogens, parasite eggs, and weed seeds in the manure, while reducing the emission of harmful gases such as ammonia and eliminating manure odor.
Crop Straw
Such crude fiber materials as corn straw, wheat straw, rice straw, etc. The chain compost turner’s teeth can tear and stir bundled or segmented straw, making it evenly mixed with other organic materials, accelerating the degradation and composting of the straw, and converting it into organic matter and humus in organic fertilizer.
Industrial Organic Waste
These materials include wine lees, vinegar lees, furfural residue, Chinese medicine residue, and slaughterhouse waste. These materials have high moisture content and are easily corrupted. The chain compost turner can reduce the moisture content of the materials through continuous turning, promote the growth of beneficial microorganisms, and achieve harmless treatment and resource utilization of waste residues.
Municipal Organic Waste
Such as kitchen waste, landscaping waste (dead branches and leaves, weeds, etc.). The chain compost turner can centrally process these scattered wastes, converting them into high-quality organic fertilizer raw materials through physical crushing and biological fermentation during the turning process, thereby reducing the amount of urban waste landfilled.
Sludge Treatment
Includes sludge from municipal sewage treatment plants and industrial wastewater treatment plants. After strict testing for heavy metal content and ensuring compliance, the chain compost turner reduces the sludge’s moisture content (from approximately 80% to below 60%) by turning it, stabilizing its properties and eliminating odor and pathogens, making it a safe organic fertilizer raw material.
Technical Parameter Comparison
| Parameter Type | Traditional Trough Turner | Chain Compost Turner |
| Operation Method | Fixed trough operation | Open windrow operation |
| Processing Capacity | 100-500 m³/day | 500-2000 m³/day |
| Investment Cost | Higher (fermentation trough required) | Lower (no infrastructure needed) |
| Application Scope | Small to medium scale production | Large-scale industrial production |
Environmental and Economic Benefits
The promotion and application of chain compost turners not only solve the problem of organic waste treatment but also create significant economic and environmental benefits. By converting waste into organic fertilizers, it achieves resource recycling, reduces the use of chemical fertilizers, improves soil structure, and provides high-quality organic fertilizer sources for agricultural production.
