The windrow compost turning machine (also known as a crawler type compost turner) is specialized fermentation equipment used in complete organic fertilizer production lines; it is primarily employed for turning and fermenting organic waste materials such as livestock and poultry manure, sludge, distillers' grains, and crop straw. As a type of self-propelled turner utilizing a crawler-based drive system, it is suitable for ground-based windrow fermentation processes. The machine employs a rotating blade shaft to mix, pulverize, aerate, and restack the material, thereby creating an optimal environment for aerobic microbial fermentation.
The operation of the windrow compost turning machine represents a classic aerobic dynamic composting process. Upon startup, a fully hydraulic drive system propels the crawler chassis smoothly, allowing the machine to straddle a pre-stacked, elongated windrow of material. Simultaneously, a rotating turning shaft mounted beneath the frame spins at high speed, lifting the material from the bottom, breaking it up, mixing it, and shifting it laterally.
This process achieves three core objectives:
Adequate oxygen supply: The turning action exposes a large surface area of the material to the air, providing sufficient oxygen for aerobic microorganisms and accelerating the decomposition of organic matter.
Temperature and moisture regulation: Turning facilitates the uniform distribution and dissipation of heat and moisture within the pile, preventing localized overheating or excessive wetness.
Pulverization and mixing: The powerful turning shaft breaks up compacted clumps formed during fermentation while thoroughly mixing microbial inoculants and bulking agents with the primary feedstock.
As the machine passes, the material naturally reforms into a new triangular windrow, seamlessly integrating the processes of turning, aeration, and pile shifting.
Fully hydraulic drive system: Provides hydraulic power for operations such as traveling, turning, and machine lifting/lowering.
Features widened and thickened wear-resistant high-manganese steel tracks, offering a large ground contact area and low ground pressure.
Equipped with alloy steel turning blades to perform integrated material turning, crushing, and mixing.
Excavator-style cabin supporting both manual and remote control operation (remote control range up to 200m).
Allows for the adjustment of the turning drum height to accommodate varying material depths.
Windrow compost turning machines are widely used in various sectors involving the resource utilization of organic waste:
Organic fertilizer plants (fermentation stage)
Large-scale livestock farms (handling chicken, cattle, and pig manure)
Agricultural waste (crop stalks, mushroom residue, traditional Chinese medicine dregs)
Municipal sludge, sugar mill filter mud, distillery grains, etc.
Suitable models are available for both organic fertilizer enterprises and large-scale livestock farms.
The crawler-based drive system exerts low ground pressure, preventing the machine from sinking or slipping on muddy fermentation sites. It eliminates the need for standardized fermentation trenches, thereby saving on civil engineering costs, and is suitable for use in both indoor greenhouses and open-air yards. The hydraulic system allows for drum height adjustment, ensuring uniform turning depth and thorough aeration of the material pile; this accelerates the decomposition of raw materials—such as livestock manure and crop stalks—shortens fermentation time, and minimizes odor generation. Equipped with wear-resistant, detachable turning tines, the machine boasts a low failure rate and facilitates easy daily maintenance and replacement. It offers flexible steering with no operational blind spots and can be operated by a single person. High turning efficiency is complemented by an integrated material-pushing mechanism, which reduces the manual labor required for organizing materials.
Huaqiang Heavy Industry has specialized in organic fertilizer equipment manufacturing for years and operates mature production lines. All crawler compost turners are manufactured in-house using high-quality materials; the load-bearing frame is thickened and reinforced for an extended service life. Models can be customized based on site size and production capacity requirements, making them suitable for small, medium, and large-scale livestock farms and organic fertilizer processing plants. Comprehensive on-site installation, commissioning, and operator training services are provided, alongside prompt after-sales support and a stable supply of spare parts. By purchasing directly from the manufacturer rather than an intermediary, you avoid multiple markups, ensuring a balance of quality and price while securing reliable, long-term, large-scale fermentation production.
