Equipment Overview
The windrow compost turner is a material fermentation processing device that utilizes a crawler walking mechanism, primarily used in organic fertilizer production to turn and stir various organic materials, creating a suitable fermentation environment. Its core operating principle is: the crawler structure enables flexible movement of the equipment across complex sites, while the turning teeth or spiral blades on the mechanical arm turn the accumulated material, allowing it to fully contact the air, regulating temperature and humidity, and accelerating microbial decomposition and maturation.
Technical Advantages
Thanks to its crawler-type walking design, this equipment can adapt to muddy and uneven fermentation sites. Compared with wheeled compost turners, it has stronger terrain adaptability and is widely used in strip-type fermentation operations in large-scale organic fertilizer production bases, farms, and municipal organic waste treatment sites.
Strong Terrain Adaptability
The crawler-type walking design reduces ground pressure, allowing free movement on muddy, soft, and complex sites with slopes ≤15° without laying special tracks. Suitable for open-air windrow fermentation, site utilization rate is more than 30% higher than trough-type compost turners.
Wide Turning Range
The hydraulic arm can flexibly adjust the turning height and width, handling stacks 1-2.5 meters high and 2-6 meters wide. A single device can turn 50-150 tons of materials per hour, with operating efficiency 1.5-2 times that of single-screw compost turners.
High Mixing Uniformity
The turning teeth flip material upward from the bottom, combined with lateral pushing during equipment movement, achieving a material turning rate over 95%, avoiding local compaction or uneven fermentation. Material temperature distribution deviation ≤3℃ ensures good composting consistency.
High Operational Flexibility
Equipped with hydraulic control system and flexible steering mechanism, enabling spot steering and small-radius turns, flexibly shuttling between windrows. Particularly suitable for alternating operations of multiple windrow rows, reducing equipment idle time.
Applicable Raw Material Range
The windrow compost turner has wide adaptability to various organic materials and can efficiently process the following raw materials:
Livestock and Poultry Manure
Including high-density organic materials such as chicken manure, pig manure, cow manure, and sheep manure. Powerful turning capability can break up compacted manure state, effectively eliminating pathogens, parasite eggs, and weed seeds through ventilation and temperature increase during turning process.
Crop Straw
Such as corn straw, wheat straw, rice straw and other crude fiber materials. The turning components can tear and mix bundled or segmented straw, making it evenly mixed with livestock manure and other materials, accelerating straw degradation and composting.
Industrial Organic Waste
Including distiller’s grains, vinegar residue, furfural residue, Chinese medicine residue, and slaughterhouse waste. These materials have high moisture content and are prone to decay. Continuous turning can reduce material moisture content and promote beneficial microorganism growth.
Municipal Organic Waste
Such as kitchen waste, landscaping waste (dead branches, leaves, weeds, etc.). These scattered wastes can be centrally processed in open sites, converted into high-quality organic fertilizer raw materials through physical crushing and biological fermentation during turning process.
Sludge
Including sludge from municipal sewage treatment plants and industrial wastewater treatment plants. After strict testing for heavy metal content compliance, turning can reduce sludge moisture content from approximately 80% to below 60%, stabilizing its properties and eliminating odors and pathogens.
Application Value
The windrow compost turner has become an indispensable asset in organic waste management, demonstrating exceptional performance advantages in modern agricultural practices. As a specialized fertilizer production machine, it significantly enhances composting efficiency while substantially reducing operational costs.
Within comprehensive organic fertilizer production line configurations, various turner types serve specific functions. The large wheel compost turner offers superior stability and mixing capability for large-scale operations, while the chain compost turner provides precise aeration and material breakdown for more sensitive composting processes. These specialized machines form the core equipments required for biofertilizer production, working synergistically to transform organic waste into valuable agricultural resources.
Integrated into complete bio organic fertilizer production line systems, the compost fertilizer machine and windrow machine collectively establish reliable technical support for harmless treatment and resource utilization of organic waste. Each fertilizer making machine contributes uniquely to the production cycle, ensuring optimal composting conditions and consistent output quality.
This comprehensive approach to organic waste management through advanced composting technology serves as fundamental equipment for promoting circular agriculture and sustainable development, bridging the gap between waste management and agricultural productivity while supporting environmental conservation efforts.
