Composting is a fundamental step in organic fertilizer production, transforming agricultural waste and animal manure into stable, nutrient-rich humus. The choice of composting method depends on raw material type, available land, and the desired processing speed. Below are some of the most widely used fertilizer composting methods and the corresponding turning equipment suitable for each.
1. Windrow Composting Method
The windrow composting system is the most common approach for large-scale fertilizer plants. Raw materials such as cow dung, chicken manure, and crop residues are piled into long windrows—usually 1.5 to 2 meters high—and turned regularly to supply oxygen.
For this method, crawler-type compost turners or self-propelled compost machines are widely used. They can move along the windrow, turning and mixing the material while breaking up clumps to ensure even fermentation. These machines are suitable for both open-air and semi-enclosed composting yards.
2. Groove Type Composting System
In facilities with limited space, groove composting (also known as trench composting) is preferred. Materials are placed into fermentation channels with fixed rails. A groove-type compost turner equipped with an automatic control system travels along the rails, turning materials layer by layer.
This method offers better temperature control and is often used in organic fertilizer production lines where consistent compost quality is required. It’s energy-efficient and suitable for continuous, large-scale operation.
3. In-Vessel Composting for Controlled Fermentation
For areas with strict environmental regulations or where odor control is essential, in-vessel composting systems or organic fermentation tanks are used. These sealed reactors maintain optimal temperature, humidity, and oxygen levels, significantly shortening fermentation time.
Although this approach requires a higher investment, it produces stable compost in as little as 7–10 days and eliminates the need for outdoor turning.
4. Hydraulic and Wheel Compost Turners
In modern composting projects, hydraulic compost turners and wheel-type compost machines are introduced for efficiency and automation. Hydraulic systems handle heavier materials and deep windrows, while wheel turners are designed for large fermentation tanks or channels exceeding 1.5 meters in depth.
Their ability to maintain uniform aeration helps reduce energy consumption and improve compost maturity. Feel free to consult YUSHUNXIN!
Conclusion
Choosing the right composting method and turning equipment depends on the scale of production, raw materials, and environmental factors. From simple windrow systems to fully enclosed fermentation reactors, each setup has its own balance between cost, efficiency, and control. A well-matched compost turner not only accelerates decomposition but also ensures stable fertilizer quality for subsequent granulation or liquid processing.
