In the crucial step of organic fertilizer production line—raw material fermentation—a windrow compost turner acts as an efficient “turning craftsman.” Its flexible crawler design allows it to easily maneuver between fermentation tanks or compost piles, making it a key piece of equipment for improving organic fertilizer quality. It can turn organic materials like livestock and poultry manure, straw, and mushroom residue. By turning the compost, it breaks up clumps, allowing air to fully enter the compost, providing ample oxygen for microbial activity and accelerating the decomposition of organic matter. This reduces the fermentation cycle from the traditional 30 days to 15-20 days, significantly improving production efficiency.
The advantages of this fertilizer equipment go far beyond efficient compost turning. Its tracks are made of high-strength, wear-resistant material and have a large ground contact area, allowing it to travel smoothly on muddy fermentation sites without compacting the raw material pile and damaging the internal breathable structure. The compost turning teeth are designed in a spiral shape, which not only allows the compost to be turned to a depth of 1.2-2 meters, but also allows the bottom layer of raw materials to be fully mixed with the surface layer of raw materials, ensuring uniform temperature in all parts of the pile (maintained at the optimal fermentation temperature of 55-65°C), effectively killing insect eggs and pathogens in the raw materials, and reducing the risk of subsequent application of organic fertilizers. At the same time, some crawler compost turners are also equipped with a spray system that can accurately add water according to the humidity of the raw materials during turning, making the fermentation process more controllable.
The crawler compost turner is also highly adaptable, flexibly adapting to applications ranging from fixed fermentation tanks in small and medium-sized organic fertilizer plants to open-air compost piles on large farms. It is also easy to operate, with forward, reverse, and compost turning movements controlled by a remote control. This allows a single person to complete the operation, reducing labor costs. With it, organic fertilizer production not only achieves “rapid fermentation and efficient sterilization,” but also ensures uniform nutrient distribution, laying a good foundation for subsequent granulation and screening.
