In the fermentation workshop or large-scale composting site of an organic fertilizer production line, the windrow compost turning machine acts like a tireless "mixer," rapidly transforming organic waste such as livestock manure and straw into high-quality fertilizer through scientific mechanical operation. Its working principle revolves around three core aspects: power transmission, material turning, and aeration fermentation, combining high efficiency and practicality.
The power system of the windrow compost turning machine is fundamental to its operation. The equipment is equipped with a high-power diesel engine or electric motor, transmitting power to the tracks and turning device through a hydraulic transmission system. The track design allows it to move freely on soft composting sites, with a large ground contact area and low pressure, preventing it from sinking into the material. It also allows for flexible adjustment of the travel speed to adapt to the operational needs of different fermentation stages.
Turning is the core process. The turning drum under the machine is equipped with high-strength spiral blades or teeth. As the equipment moves forward, the drum rotates at high speed, and the blades penetrate deep into the compost material, turning and breaking up the bottom layer of material while simultaneously turning the surface material to the bottom. This process achieves three key benefits: first, it breaks up the compacted material layer, allowing oxygen to fully enter the compost pile and meet the respiratory needs of aerobic microorganisms; second, it ensures uniform temperature across the compost layers, preventing localized overheating or incomplete fermentation; and third, it breaks up clumps formed during fermentation, improving material permeability.
Furthermore, the equipment has auxiliary functions to ensure fermentation quality. Some models are equipped with a spray system that can simultaneously spray microbial agents or adjust moisture during turning, optimizing the fermentation environment. The track's trajectory can be set via an electronic control system, enabling fully automatic turning and reducing manual intervention. After turning, the material forms loose windrows, where microorganisms rapidly decompose organic matter in an aerobic environment. After several turns, the original waste is transformed into well-rotted organic fertilizer.
The windrow compost turning machine simplifies the complex composting process into a highly efficient mechanized operation through a closed-loop operation of "power transmission - mechanical turning - aeration and fermentation." This not only significantly improves fermentation efficiency but also ensures the uniformity of organic fertilizer quality, making it a key piece of equipment for the resource utilization of modern agricultural waste.
